Abstract

Electrical switchgear for fitment to installation circuit breakers. Known switchgears have one or more contact points on which a switch mechanism acts, the switch mechanism interacting with an adjacent circuit breaker. Differential operation of the contact points is thus not possible. To operate the switch poles 35, 45, a switch mechanism 36, 46 is provided in each case, which switch mechanisms are independent of one another and in each case have a coupling element which engages with the adjacent circuit breaker. In this case, each switch mechanism 36, 46 operates a switch pole 35, 45 which in each case is designed as a two-way switch. The arrangement permits the optional connection of the switch poles as opening or closing contacts and allows them to be operated differentially.

Description

Die Erfindung betrifft ein elektrisches Schaltgerät zum Anbau an Installations-Selbstschalter, insbesondere Leitungsschutzschalter, mit Kontaktstellen für wenigstens zwei potentialfreie Schalterpole, die von einer Betätigungseinrichtung beaufschlagt sind, welche mit einem oder mehreren Kupplungsgliedern zusammenarbeitet, welche die Flachseiten der in Schmalbauweise ausgebildeten Gehäuse des Schaltgeräts und gegebenenfalls eines angrenzenden Selbstschalters durchgreifen, wobei sie dessen Schaltstellung über die Betätigungseinrichtung auf die Schalterpole übertragen können.The invention relates to an electrical switchgear for mounting on automatic circuit breakers, in particular circuit breakers, with contact points for at least two potential-free switch poles, which are acted upon by an actuating device which cooperates with one or more coupling members which cover the flat sides of the housing of the switchgear and which have a narrow construction if necessary, reach through an adjacent circuit breaker, where they can transmit its switch position to the switch poles via the actuating device.

In elektrischen Niederspannungsschaltanlagen, deren Stromkreise durch Leitungsschutzschalter und ggf. durch Fehlerstromschutzschalter abgesichert sind, besteht häufig der Bedarf, gleichzeitig mit der durch Ansprechen infolge Überstrom oder Kurzschlußstrom bzw. Fehlerstrom erfolgten Auslösung der Sicherungsselbstschalter und der damit einhergehenden Unterbrechung der Hauptstromkreise sogenannte Hilfsstromkreise zu schalten, d. h. ein- oder auszuschalten.In electrical low-voltage switchgear, the circuits of which are protected by miniature circuit breakers and, if applicable, by residual current circuit breakers, there is often a need to trigger the safety circuit breakers and the circuit breaker by tripping as a result of overcurrent or short-circuit current or fault current associated interruption of the main circuits to switch so-called auxiliary circuits, ie to switch them on or off.

Für diesen Zweck sind Hilfsschalter vorgesehen, welche neben den in Zählerplätzen installierten Selbstschaltern zur Absicherung der Hauptstromkreise zusätzlich angeordnet werden. Hierbei bietet sich an, die Hilfsschalter an einen fest installierten Selbstschalter anzubauen und mechanisch mit dessen Auslöser zu koppeln, so daß im Auslösefall sowohl der Selbstschalter als auch der daran angebaute Hilfsschalter gleichzeitig betätigt werden.Auxiliary switches are provided for this purpose, which are arranged in addition to the self-switches installed in meter stations to protect the main circuits. It is advisable to attach the auxiliary switch to a permanently installed self-switch and to couple it mechanically to its release, so that in the event of a trip both the self-switch and the auxiliary switch attached to it are operated simultaneously.

Ein derartiges Hilfsschalter-Anbauteil für Leitungsschutzschalter ist aus dem deutschen Gebrauchsmuster DE-GM 74 26 189 bekannt geworden, das in einem vom Leitungsschutzschalter getrennten Raum Hilfskontakte aufweist, die von einer Betätigungseinrichtung beaufschlagt sind, die mit dem angrenzenden Selbstschalter in Eingriff steht. Das Hilfsschalter-Anbauteil weist mehrere übereinander angeordnete Kontaktstellen auf, die von nebeneinander liegenden Festkontaktstücken gebildet sind, welche jeweils mittels einer Kontaktbrücke verbindbar sind.Such an auxiliary switch attachment for circuit breakers has become known from German utility model DE-GM 74 26 189, which has auxiliary contacts in a space separated from the circuit breaker, which are acted upon by an actuating device which engages with the adjacent circuit breaker. The auxiliary switch attachment has a plurality of contact points arranged one above the other, which are formed by fixed contact pieces lying next to one another, each of which can be connected by means of a contact bridge.

Die Kontaktbrücken sind an einem als Schieber ausgebildeten Kontaktbrückenträger befestigt, der über einen Schwenkhebel von einem Betätigungsglied des benachbarten Selbstschalters verschiebbar ist. Bei Änderung der Schaltstellung des Selbstschalters ändert sich gleichzeitig über dieses Betätigungsglied auch die Stellung des Kontaktbrückenträgers und damit die Schaltstellung im Hilfsschalter-Anbauteil.The contact bridges are fastened to a contact bridge carrier designed as a slide, which can be displaced by an actuating element of the adjacent circuit breaker via a swivel lever. When changing the switch position of the circuit breaker, the position of the contact bridge support and thus the switch position in the auxiliary switch add-on part also change via this actuator.

Durch Umbau der Kontaktbrücke auf dem Kontaktbrückenträger ist es möglich, die Kontaktstelle des Hilfsschalters wahlweise je nach Bedarf als Öffner oder als Schließer einzusetzen.By converting the contact bridge on the contact bridge support, it is possible to use the contact point of the auxiliary switch as an opener or a closer as required.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, ein Schaltgerät der eingangs genannten Art hinsichtlich seiner Handhabung, Funktionssicherheit und Verwendungsbreite zu verbessern. Dabei soll der Schalter kompakt gestaltet und einfach handhabbar sein.Based on this prior art, it is an object of the invention to improve a switching device of the type mentioned in terms of its handling, functional reliability and range of use. The switch should be compact and easy to use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Betätigungseinrichtung aus zwei voneinander unabhängigen Schaltwerken gebildet ist, die jeweils ein Kupplungsglied besitzen, das gegebenenfalls mit dem angrenzenden Selbstschalter im Eingriff steht, daß jedes Schaltwerk wenigstens einen Schalterpol beaufschlagt, daß jeder Schalterpol als Wechselschalter ausgebildet ist und daß die Betätigungseinrichtung einen ersten Schaltgriff und einen zweiten Schaltgriff aufweist.This object is achieved in that the actuating device is formed from two mutually independent switching mechanisms, each having a coupling member, which may be in engagement with the adjacent self-switch, that each switching mechanism acts on at least one switch pole, that each switch pole is designed as a changeover switch and that the actuating device has a first control handle and a second control handle.

In einer bevorzugten Ausgestaltung der Erfindung kann vorgesehen sein, daß ein erster Schalterpol als Signalschalter zur Anzeige der Einschaltstellung oder der infolge Störfall, d. h. Kurzschluß- oder Überstrom, verursachten Ausschaltstellung des Selbstschalters dient, während der wenigstens zweite Schalterpol zum Ein- und Ausschalten von sonstigen Hilfsstromkreisen dient.In a preferred embodiment of the invention it can be provided that a first switch pole as a signal switch for indicating the switch-on position or the result of a malfunction, ie. H. Short-circuit or overcurrent, caused switch-off position of the self-switch is used, while the at least second switch pole is used to switch other auxiliary circuits on and off.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, das Schaltwerk des ersten Schalterpols, der als Signalpol eingesetzt wird, mit einer Prüfeinrichtung zur Kontrolle der einwandfreien Funktion des Schaltwerks auszustatten.An advantageous embodiment of the invention provides for the switching mechanism of the first switch pole, which is used as a signal pole, to be equipped with a test device Check that the rear derailleur is working properly.

Insbesondere kann aber diese Prüfeinrichtung auch zur Kontrolle eines mit diesem Schalterpol geschalteten Signalstromkreises dienen. Es ist dabei auch an die Möglichkeit gedacht, daß bei erfolgter Auslösung des angrenzenden Selbstschalters das in diesem Fall vorgesehene Signal wegen eines Fehlers im Signalstromkreis unterbleibt. Auch um solche Fehlerquellen ohne Unterbrechung des Hauptstromkreises ausfindig machen zu können, ist die Prüfeinrichtung vorgesehen.In particular, however, this test device can also be used to control a signal circuit connected with this switch pole. It is also contemplated that if the adjacent circuit breaker is triggered, the signal provided in this case will not appear due to an error in the signal circuit. The test facility is also provided in order to be able to locate such sources of error without interrupting the main circuit.

Diese Prüfeinrichtung ist gebildet aus einer federbelasteten längsverschieblichen Prüftaste mit stirnseitiger Tastfläche und einer an ihrer entgegengesetzten Stirnseite schrag angeformten Gleitfläche, welche mit einem Auslösehebel des Schaltwerks für den Signalschalter zusammenwirkt.This test device is formed from a spring-loaded, longitudinally displaceable test button with a key surface on the end face and a sliding surface formed obliquely on its opposite end face, which cooperates with a release lever of the switching mechanism for the signal switch.

Bei Betätigung der Prüfeinrichtung d. h. beim Niederdrücken der Prüftaste, beaufschlagt ihre Gleitfläche eine Schieberplatte mit einer Auslösenase, die ihrerseits den Auslösehebel des Schaltwerks aus seiner Ruhelage bewegt und damit zur Entklinkung des Schaltwerks führt, woraufhin der zugehörige Schalterpol in Ausschaltstellung gelangt. Gleichzeitig mit der Bewegung der Schieberplatte beaufschlagt ein daran befestigter oder einstückig angeformter Mitnehmerzapfen einen am zugehörigen Schaltgriff hierzu vorgesehenen, mit einer Rastnase versehenen Mitnehmer und verschiebt diesen so, daß der Schaltgriff in die "Aus"-Stellung gelangt.When the test device is actuated, ie when the test button is depressed, its sliding surface acts on a slide plate with a release lug, which in turn moves the release lever of the rear derailleur from its rest position and thus leads to the release of the rear derailleur, whereupon the associated switch pole comes into the off position. Simultaneously with the movement of the slide plate, an attached or integrally formed driver pin acts on a driver provided on the associated control handle, provided with a detent and moves it so that the control handle comes to the "off" position.

Wie bereits erwähnt, ist gemäß der Erfindung vorgesehen, daß die Schaltwerke für die Schalterpole unabhängig voneinander durch den angrenzenden Selbstschalter beaufschlagt werden.As already mentioned, it is provided according to the invention that the switching mechanisms for the switch poles are acted upon independently of one another by the adjacent self-switch.

Der Signalschalter, der insbesondere zur Anzeige von Fehlerzuständen im Hauptstromkreis des Selbstschalters - Kurzschluß- oder Überstrom - dient, ist hierzu über das seinem Schaltwerk zugeordnete Kupplungsglied mit einem Auslöseorgan des Selbstschalters verbunden. Dieses Auslöseorgan seinerseits arbeitet sowohl mit dem magnetischen als auch mit dem thermischen Auslöser des Selbstschalters zusammen und überträgt so dessen Bewegung unmittelbar auf das Kupplungsglied, welche das Schaltwerk des Signalschalters betätigt.The signal switch, which is used in particular to indicate error states in the main circuit of the circuit breaker - short circuit or overcurrent - is connected to a triggering element of the circuit breaker via the coupling element assigned to its switching mechanism. This release element in turn works with both the magnetic and the thermal release of the circuit breaker and thus transmits its movement directly to the coupling member, which actuates the switching mechanism of the signal switch.

Das Schaltwerk des wenigstens zweiten Schalterpoles, der vorzugsweise als Hilfsschalter zur Ein- und Ausschaltung sonstiger Hilfsstromkreise dient, steht über das ihm zugeordnete Kupplungsglied im Eingriff mit dem beweglichen Kontaktstück des Selbstschalters.The switching mechanism of the at least second switch pole, which is preferably used as an auxiliary switch for switching on and off other auxiliary circuits, is in engagement with the movable contact piece of the circuit breaker via the coupling member assigned to it.

Bei den bekannten Selbstschaltern, auf die die Erfindung Bezug nimmt, ist das bewegliche Kontaktstück mechanisch mit dem Handbetätigungsorgan des Selbstschalters gekoppelt und kann demzufolge von diesem manuell betätigt werden. Dementsprechend wird bei jeder manuellen Betätigung des Handbetätigungsorgans des Selbstschalters, die sich auf das bewegliche Kontaktstück überträgt, gleichzeitig der als Hilfsschalter vorgesehene wenigstens zweite Schalterpol des angebauten elektrischen Schalters betätigt.In the known automatic switches to which the invention relates, the movable contact piece is mechanically coupled to the manual operating element of the automatic switch and can therefore be operated manually by the latter. Accordingly, with each manual actuation of the manual control element of the automatic switch, which is transferred to the movable contact piece, the at least second switch pole of the attached electrical switch, which is provided as an auxiliary switch, is simultaneously actuated.

Auch der elektrische Schalter besitzt gemäß der Erfindung ein Schaltbetätigungsorgan, das auf der Gehäusevorderseite herausgeführt ist und formschlüssig mit dem Selbstschalter-Handbetätigungsorgan verbunden zum manuellen Einschalten des angebauten Hilfs- und Signalschalters dient.According to the invention, the electrical switch also has a switching actuating element which is led out on the front side of the housing and is connected in a form-fitting manner to the self-switching manual actuating element for manually switching on the attached auxiliary and signal switch.

Dabei ist das Schaltwerk des ersten Schalterpols, der als Signalschalter dient, in vorteilhafter Weise so gestaltet, daß der Signalpol wohl eingeschaltet werden kann, jedoch nicht durch manuelle Betätigung des Handbetätigungsorgans des Selbstschalters in Ausschaltstellung gebracht werden kann.The switching mechanism of the first switch pole, which serves as a signal switch, is advantageously designed in such a way that the signal pole can be switched on, but cannot be brought into the switched-off position by manual actuation of the manual control element of the self-switch.

Dies hat zur Folge, daß der Signalschalter, nach seiner Einschaltung nur durch Betätigung der Prüftaste oder durch einen tatsächlich auftretenden Kurzschluß- oder Uberstrom in Ausschaltstellung gelangt, unabhängig davon, ob der angrenzende Selbstschalter manuell in Ausschaltstellung gebracht wurde, wobei sich jedoch die Ausschaltung des Signalkontakts mittels der Prüfeinrichtung nicht überträgt auf den angrenzenden Selbstschalter.The result of this is that the signal switch, after being switched on, only comes into the switched-off position by pressing the test button or by a short-circuit or overcurrent that actually occurs, regardless of whether the adjacent self-switch was brought into the switched-off position manually, but the signal contact is switched off by means of the test facility not transferred to the adjacent self-switch.

Gemäß einer weiteren besonderen Ausgestaltung der Erfindung ist der elektrische Schalter mit einem Handbetätigungsorgan versehen, welches als visuelle Schaltstellungsanzeige dient.According to a further special embodiment of the invention, the electrical switch is provided with a manual actuating element which serves as a visual switch position indicator.

Hierbei ist das Betätigungsorgan aus zwei Schaltgriffen, die um eine gemeinsame Drehachse schwenkbar angeordnet sind, gebildet. Der erste Schaltgriff, der zur Unterscheidung eine andere Farbe aufweist als der zweite Schaltgriff, ist mit dem Schaltwerk des Signalpols verbunden. Der zweite der beiden Schaltgriffe ist zum formschlüssigen Eingriff in das Handbetätigungsorgan des angrenzenden Selbstschalters vorbereitet und dient zum gleichzeitigen Einschalten der Schaltgeräte. Darüber hinaus besitzt er einen Mitnehmer, der dazu dient, das Schaltwerk des Signalpols in Einschaltstellung zu bringen.Here, the actuating member is formed from two control handles which are arranged pivotably about a common axis of rotation. The first control handle, which has a different color than the second control handle to distinguish it, is connected to the switching mechanism of the signal pole. The second of the two control handles is for prepared form-fitting intervention in the manual control element of the adjacent self-switch and serves to switch on the switching devices at the same time. In addition, it has a driver that serves to bring the signal pole switch mechanism into the ON position.

Wie zuvor bereits erwähnt, kann das Schaltwerk des Signalschalters gemeinsam mit dem angrenzenden Selbstschalter oder allein manuell eingeschaltet werden; eine manuelle Auschaltung des Signalpols ist jedoch nicht möglich. Dies ist auch nicht möglich mit dem unmittelbar mit dem Schaltwerk des Signalpols in Eingriff stehenden Schaltgriff, da die im Schaltwerk vorgesehene Verklinkung nur durch Betätigung der Prüftaste bzw. durch Akti-vierung des thermischen oder Magnetauslösers des Selbstschalters auslösbar ist. Beides führt jeweils zu einer Lageveränderung des Kupplungsgliedes und damit zu einer Auslösung des Schaltwerks des Signalschalters.As already mentioned above, the switching mechanism of the signal switch can be switched on manually together with the adjacent self-switch or alone; however, manual deactivation of the signal pole is not possible. This is also not possible with the control handle that is directly engaged with the switching mechanism of the signal pole, since the latch provided in the switching mechanism can only be triggered by actuating the test button or by activating the thermal or magnetic release of the circuit breaker. Both lead to a change in position of the coupling member and thus to a triggering of the switching mechanism of the signal switch.

In einer bevorzugten Ausgestaltung der Erfindung ist der elektrische Anbauschalter in einem doppelschaligen Gehäuse untergebracht, welches aus spiegelbildlich geformten Halbschalen besteht. Die Teilungsebene des Schaltergehäuses, dessen Dicke der halben Modulbreite der üblichen Selbstschalter entspricht, verläuft bei halber Dikke parallel zur Flachseite des Schaltergehäuses und teilt dieses in zwei gleich dicke Hälften, welche die Einzelteile des Schalters einschließlich der Anschlußklemmen aufnehmen.In a preferred embodiment of the invention, the electrical add-on switch is accommodated in a double-shell housing which consists of half-shells formed in mirror image. The division level of the switch housing, the thickness of which corresponds to half the module width of the usual self-switches, runs at half the thickness parallel to the flat side of the switch housing and divides it into two halves of equal thickness, which accommodate the individual parts of the switch including the connecting terminals.

Auf diese Weise ist es möglich, die üblicherweise mit Klemmschrauben versehenen Anschlußklemmen, die in vorgeformte Ausnehmungen der Gehäuseschalen eingesetzt sind, verdrehungssicher auch gegen hohe Drehmomente beim Festklemmen der elektrischen Anschlußleiter ohne weitere Maßnahmen, z. B. Verkleben, zu installieren.In this way, it is possible to use the connecting terminals, which are usually provided with clamping screws and are inserted into pre-formed recesses in the housing shells, torsion-proof even against high torques when clamping the electrical connection conductors without further measures, e.g. B. Glue to install.

Ein weiterer Vorteil der Erfindung ist darin zu sehen, daß die Kontaktstellen für die Schalterpole, Signalschalter und Hilfsschalter, jeweils als Wechselschalter ausgebildet sind, so daß ohne zusätzlichen Aufwand ein wahlweiser Einsatz als Schließer oder Öffner gewährleistet ist.Another advantage of the invention can be seen in the fact that the contact points for the switch poles, signal switches and auxiliary switches are each designed as changeover switches, so that an optional use as NO or NC contact is ensured without additional effort.

Die Anschlußbelegung für die Kontaktstellen ist in bekannter Weise jeweils an den den Schalterpolen zugewandten oberen und unteren Stirnseiten vorgesehen, wobei jede Anschlußklemme mit ihren Klemmschrauben versenkt angeordnet nur mit Werkzeug erreichbar ist.The pin assignment for the contact points is provided in a known manner on the upper and lower end faces facing the switch poles, with each connecting terminal recessed with its clamping screws being accessible only with tools.

Zur Verbindung der Gehäuseschalen sind bei deren Herstellung wechselweise angeformte Haken und entsprechende Ausnehmungen vorgesehen, die ineinandergreifen.To connect the housing shells, alternately molded hooks and corresponding recesses are provided, which interlock.

Der Anbau des elektrischen Schalters an einen Selbstschalter ist jederzeit, d. h. auch nachträglich durch den Kunden, möglich, sofern die vorgesehenen Selbstschalter hierfür vorbereitet sind.The electrical switch can be attached to a circuit breaker at any time, i. H. also possible retrospectively by the customer, provided that the provided automatic switches are prepared for this.

Nach einer besonderen Ausgestaltung der Erfindung ist das Schaltgerät am Selbstschalter mittels Klammern befestigt, die die Schmalseiten der beiden Gehäuse jeweils umfassen und in Ausnehmungen auf den Flachseiten formschlüssig einrasten.According to a special embodiment of the invention, the switching device is fastened to the self-switch by means of clamps which each encompass the narrow sides of the two housings and engage in a form-fitting manner in recesses on the flat sides.

Nach einer anderen Ausgestaltung sind stiftförmige Verbindungselemente, z. B. Schrauben oder Nieten, zur Befestigung vorgesehen, die die Gehäuse durchdringen.According to another embodiment, pin-shaped connecting elements, for. B. screws or rivets, provided for attachment, which penetrate the housing.

Diese und weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.These and further advantageous refinements of the invention are specified in the subclaims.

Anhand der Zeichnung, die ein Ausführungsbeispiel der Erfindung wiedergibt, sollen die Erfindung, vorteilhafte Ausgestaltungen und weitere Vorteile der Erfindung näher erläutert und beschrieben werden.The invention, advantageous refinements and further advantages of the invention are to be explained and described in more detail with reference to the drawing, which represents an exemplary embodiment of the invention.

In Figur 1 ist eine Anordnung von elektrischen Selbstschaltern 10 und einem erfindungsgemäßen elektrischen Schaltgerät 12 dargestellt, die auf einer Tragschiene 14 befestigt sind.FIG. 1 shows an arrangement of electrical circuit breakers 10 and an electrical switching device 12 according to the invention, which are fastened on a mounting rail 14.

Die elektrischen Selbstschalter 10 sind in bekannter Weise mit nicht näher dargestellten Auslöseorganen -  thermischen und Magnetauslösern - versehen zur selbsttätigen Auslösung der zuvor eingeschalteten Selbstschalter 10. Das zwischen zwei elektrischen Selbstschaltern 10 angeordnete erfindungsgemäße Schaltgerät 12 besitzt, wie nachstehend noch ausführlich erläutert werden soll, keinen Selbstauslöser, sondern ist mit Hilfe von in dieser Darstellung nicht erkennbaren Kupplungsgliedern 16 an einen der angrenzenden Selbstschalter 10 angekoppelt.The electrical self-switches 10 are provided in a known manner with triggering elements (thermal and magnetic triggers), which are not shown in detail, for the automatic triggering of the previously switched on self-switches 10. The switching device 12 according to the invention arranged between two electrical self-switches 10 has, as will be explained in detail below, no self-trigger , but is coupled to one of the adjacent self-switches 10 with the aid of coupling members 16 which cannot be seen in this illustration.

Wie dieser Darstellung ferner zu entnehmen ist, folgt die Kontur des Gehäuses des erfindungsgemäßen Schaltgerätes 12 der Formgebung der Selbstschalter 10, d. h., das Schaltgerät 12 bildet mit den daneben aufgereihten Selbstschaltern 10 einen einheitlichen Schalterblock.As can also be seen from this illustration, the contour of the housing of the switching device 12 according to the invention follows the shape of the self-switches 10, i. that is, the switching device 12 forms a uniform switch block with the self-switches 10 lined up next to it.

Ferner ist in Figur 1 gezeigt, daß das Schaltgerät 12 ein aus zwei Schaltgriffen 20, 21 gebildetes Betätigungsorgan aufweist, welches mit den Schaltknebeln 22 der benachbarten Selbstschalter 10, 11 fluchtet.It is also shown in FIG. 1 that the switching device 12 has an actuating member formed from two switching handles 20, 21, which is aligned with the switching knobs 22 of the adjacent automatic switches 10, 11.

Ferner besitzt das Schaltgerät 12 beiderseits des Betätigungsorgans 20, 21 je drei nebeneinander angeordnete Klemmschrauben 24, welche zu in dieser Darstellung nicht gezeigten Schraubklemmen 25 gehören, die über an den schmalen Stirnseiten des Schaltgeräts 12 übereinander angeordnete Zugangsöffnungen 26 erreichbar sind.Furthermore, the switching device 12 has on both sides of the actuator 20, 21 three juxtaposed clamping screws 24, which belong to screw terminals 25, not shown in this illustration, which are connected to the Narrow end faces of the switching device 12 access openings 26 arranged one above the other can be reached.

Dagegen ist bei den Selbstschaltern 10 an jeder der beiden schmalen Stirnseiten jeweils nur ein elektrischer Anschluß 28 vorgesehen, der über Zugangsöffnungen 29 erreichbar ist. Die Selbstschalter 10 sind in bekannter Weise mit einer Nut 30 versehen, die eine fest angeformte Rastnase sowie einen beweglichen Rastschieber aufweist, mit denen die Selbstschalter 10 auf der als Hutprofilschiene ausgebildeten Tragschiene 14 aufgeschnappt sind.In contrast, in the case of the automatic switches 10, only one electrical connection 28 is provided on each of the two narrow end faces, which can be reached via access openings 29. The self-switches 10 are provided in a known manner with a groove 30 which has a firmly formed locking lug and a movable locking slide with which the self-switches 10 are snapped onto the mounting rail 14 which is designed as a top-hat rail.

In Figur 2 ist das Schaltgerät 12 einzeln in Schrägansicht dargestellt, wobei insbesondere die vorher nicht erkennbaren Kupplungsglieder 16, 18 gezeigt sind, sowie die an der Schalterrückseite eingeformte Nut 31, welche die Tragschiene 14 aufnimmt.In Figure 2, the switching device 12 is shown individually in an oblique view, in particular the previously unrecognizable coupling members 16, 18 are shown, as well as the groove 31 formed on the rear of the switch, which receives the mounting rail 14.

Im Gegensatz zu den Selbstschaltern 10 weist die Nut 31 weder eine fest angeformte Rastnase noch einen beweglichen Rastschieber auf, da nur die Befestigung am angrenzenden Selbstschalter 11 in Halteöffnungen 34 vorgesehen ist.In contrast to the self-switches 10, the groove 31 has neither a firmly formed locking lug nor a movable locking slide, since only the attachment to the adjacent self-switch 11 is provided in holding openings 34.

Die Kupplungsglieder 16, 18, welche im Abstand zueinander eine Flachseite 32 des Schaltgeräts 12 durchdringen, sind in gekrümmt verlaufenden Spalten 17, 19 - ähnlich einer Schaltkulisse - in der Seitenwand 32 des Schaltgerätes 12 geführt.The coupling members 16, 18, which penetrate a flat side 32 of the switching device 12 at a distance from one another, are guided in curved columns 17, 19 - similar to a switching link - in the side wall 32 of the switching device 12.

Zur Befestigung an dem Selbstschalter 11, wie in Figur 1 gezeigt, dienen die Halteöffnungen 34, welche zur Aufnahme von nicht näher gezeigten Halteelementen dienen, die kraft- und/oder formschlüssig mit dem Selbstschalter 11 verbunden sind.For fastening to the self-switch 11, as shown in FIG. 1, the holding openings 34, which serve to hold holding elements (not shown in more detail), which are non-positively and / or positively connected to the automatic switch 11.

Figur 3 zeigt den Längsschnitt durch das Schaltgerät 12. In dieser Darstellung ist erkennbar, daß das Schaltgerät 12 zwei Schalterpole 35, 45, die jeweils von einem zugeordneten Schaltwerk 36, 46 beaufschlagt sind, aufweist. Jeder der Schalterpole ist als Wechselschalter ausgebildet und besitzt jeweils drei Anschlußklemmen 25 zum Anschluß der elektrischen Zu- und Abgangsleitungen. Die der Rückseite mit der Nut 31 nächstliegenden Anschlußklemmen 25 dienen als Zugangsklemmen 37, 47, während die darüberliegenden Anschlußklemmen 25 als Abgangsklemmen 38, 39, 48, 49 vorgesehen sind.Figure 3 shows the longitudinal section through the switching device 12. In this illustration it can be seen that the switching device 12 has two switch poles 35, 45, each of which is acted upon by an associated switching mechanism 36, 46. Each of the switch poles is designed as a changeover switch and has three connection terminals 25 for connecting the electrical supply and output lines. The terminals 25 closest to the rear with the groove 31 serve as access terminals 37, 47, while the terminals 25 above are provided as outgoing terminals 38, 39, 48, 49.

Die Zugangsklemmen 37, 47 sind jeweils über ein flexibles Leiterstück 50, 51 mit einem beweglichen Kontakt 52, 53 verbunden.The access terminals 37, 47 are each connected to a movable contact 52, 53 via a flexible conductor piece 50, 51.

Jeder der beweglichen Kontakte 52, 53 ist aus einem Drehhebel 54, 55 sowie einem daran angeformten Kontaktarm 56, 57 mit Kontaktstück zusammengesetzt.Each of the movable contacts 52, 53 is composed of a rotary lever 54, 55 and a contact arm 56, 57 formed thereon with a contact piece.

Die Kontaktarme 56, 57 schwenken infolge Beaufschlagung durch die Schaltwerke 36, 46 von einem festen Kontaktstück 60, 61 zu einem gegenüberliegenden festen Kontaktstück 62, 63.The contact arms 56, 57 pivot due to the action of the switching mechanisms 36, 46 from a fixed contact piece 60, 61 to an opposite fixed contact piece 62, 63.

Für die Verbindung mit den Schaltwerken 36, 46 dienen Stellarme 58, 59, die an die Drehhebel 54, 55 angreifen. Als elektrische Isolierung zwischen den beweglichen Kontakten 52, 53 ist eine Zwischenwand 42 vorgesehen, welche oberhalb der Nut 31 an die Rückwand des Schaltergehäuses 40 angeformt ist.Actuating arms 58, 59, which engage the rotary levers 54, 55, are used for the connection to the switching mechanisms 36, 46. An intermediate wall 42 is provided as electrical insulation between the movable contacts 52, 53 and is formed above the groove 31 on the rear wall of the switch housing 40.

Der in Figur 3 rechts von der Zwischenwand 42 angeordnete Schalterpol 35 ist gemäß der Erfindung als Signalschalter vorgesehen und wird im bestimmungsgemäßen Betrieb über das Kupplungsglied 18, welches an das Schaltwerk 36 gekoppelt ist, vom angrenzenden Selbstschalter 11 betätigt, wenn dessen thermischer oder magnetischer Auslöser angesprochen hat.The switch pole 35 arranged in FIG. 3 to the right of the intermediate wall 42 is provided according to the invention as a signal switch and is actuated by the adjacent self-switch 11 when the thermal or magnetic trigger is activated, via the coupling member 18, which is coupled to the switching mechanism 36 Has.

Eine manuelle Betätigung des beweglichen Kontakts des Signalschalterpols 35 ist gemäß der Erfindung nur durch Betätigung einer Prüfeinrichtung 44 möglich. Die Prüfeinrichtung 44 ist aus einem federbelasteten Taster mit Tastfläche gebildet, der neben dem Betätigungsorgan 20, 21 angeordnet ist und, wie in Figur 3 zu erkennen, eine schräg angestellte Gleitfläche 64 besitzt, welche einen Auslösestift 66 beaufschlagt, dessen Lageveränderung zur Betätigung des beweglichen Kontakts 52 durch das Schaltwerk 36 führt.According to the invention, manual actuation of the movable contact of the signal switch pole 35 is only possible by actuating a test device 44. The test device 44 is formed from a spring-loaded button with a tactile surface, which is arranged next to the actuating member 20, 21 and, as can be seen in FIG. 3, has an obliquely positioned sliding surface 64 which acts on a release pin 66, the change in position thereof for actuating the movable contact 52 leads through the switching mechanism 36.

Die in Figur 3 dargestellte Schalterstellung ist mit Rücksicht auf die Stellung des Betätigungsorgans 21 als Ausschaltstellung definiert, da bei dieser Stellung des Handschaltknebels 22 der Selbstschalter 10, 11 deren Kontakte geöffnet sind.The switch position shown in FIG. 3 is defined with regard to the position of the actuating member 21 as the switch-off position, since in this position of the manual control knob 22 the self-switch 10, 11 whose contacts are open.

Der links von der Zwischenwand 42 angeordnete Schalterpol 45 dient als Hilfsschalter zur Ein- bzw. Ausschaltung von Hilfsstromkreisen im Falle von über- oder kurzschlußstrombedingter Auslösung des Selbstschalters.The switch pole 45 arranged to the left of the intermediate wall 42 serves as an auxiliary switch for switching on or off auxiliary circuits in the event of the circuit breaker being triggered by overcurrent or short-circuit current.

Das Schaltwerk 46 besteht aus zwei Hebelarmen 72, 74, die miteinander unter einem bestimmten Winkel starr verbunden sind und um einen Drehpunkt 70 schwenken, wenn das Kupplungsglied 16, welches mit dem beweglichen Kontakt des angrenzenden Selbstschalters 11 im Eingriff steht, bewegt wird. Hierbei vollzieht der Doppelhebel 72, 74 eine Schwenkbewegung, durch welche der Kontaktarm 57 des beweglichen Kontakts 53 zum anderen Festkontakt 63 geschwenkt wird.The rear derailleur 46 consists of two lever arms 72, 74 which are rigidly connected to one another at a certain angle and pivot about a pivot point 70 when the coupling member 16, which is in engagement with the movable contact of the adjacent circuit breaker 11, is moved. Here, the double lever 72, 74 executes a pivoting movement, by means of which the contact arm 57 of the movable contact 53 is pivoted to the other fixed contact 63.

Die Anschlußklemmen 25 sind durch tunnelähnliche Ausnehmungen 24 für Betätigungswerkzeuge, z. B. Schraubendreher, zugänglich sowie über Zuführungsöffnungen 26 für den Anschluß elektrischer Leitungen.The terminals 25 are through tunnel-like recesses 24 for actuating tools, for. B. screwdriver, accessible and through feed openings 26 for connecting electrical lines.

Ferner ist gemäß der Erfindung vorgesehen, daß das zweigeteilte Betätigungsorgan gleichzeitig als Schaltstellungsanzeige für den Signalschalterpol 35 dient. Dabei ist vorgesehen, daß der erste Schaltgriff 20, der in Figur 3 vom zweiten Schaltgriff 21 verdeckt ist und direkt mit dem Schaltwerk 36 des Signalschalterpols verbunden ist, die jeweilige Schaltstellung des beweglichen Kontakts 52 des Signalschalterpols 35 angibt. Hierdurch ist ermöglicht, den Signalschalterpol 35 nach dessen Ausschaltung manuell wieder einzuschalten.It is further provided according to the invention that the two-part actuator serves simultaneously as a switch position indicator for the signal switch pole 35. It is provided that the first switching handle 20, which is covered by the second switching handle 21 in FIG. 3 and is connected directly to the switching mechanism 36 of the signal switch pole, indicates the respective switching position of the movable contact 52 of the signal switch pole 35. This enables the signal switch pole 35 to be switched on again manually after it has been switched off.

Ein am Schaltwerk 36 vorgesehener Betätigungsstift 67 arbeitet dabei mit einem am zweiten Schaltgriff 21 angeordneten, nicht näher gezeigten Mitnehmer zusammen. Damit ist es möglich, bei ausgelöstem Schaltwerk 36 dieses in seine Einschaltstellung zurückzuführen.An actuating pin 67 provided on the switching mechanism 36 cooperates with a driver, not shown, arranged on the second switching handle 21. It is thus possible, when the switching mechanism 36 is triggered, to return it to its switched-on position.

Figur 4 gibt das in Figur 2 gezeigte und vorstehend erläuterte Schaltgerät 12 in der Schaltstellung "Ein" im Längsschnitt wieder.FIG. 4 shows the switching device 12 shown in FIG. 2 and explained above in the switching position "on" in a longitudinal section.

Hinsichtlich der Einzelheiten des Schaltgeräts 12, die in Figur erkennbar sind, wird auf die Erlauterungen zu Figur 3 Bezug genommen, da sie mit den dort erläuterten Einzelheiten übereinstimmen und sich lediglich in der Schaltstellung unterscheiden. Die unterschiedliche Schaltstellung ist zunächst einfach erkennbar im Vergleich mit Figur 3.With regard to the details of the switching device 12, which can be seen in the figure, reference is made to the explanations relating to FIG. 3, since they correspond to the details explained there and differ only in the switching position. The different switching position is initially easy to see in comparison with FIG. 3.

Die Kontaktarme 56, 57 der beweglichen Kontakte 52, 53 sind jeweils zum anderen Festkontakt 62, 63 verschwenkt. Ferner zeigt sich die andere Schaltstellung auch an der Stellung des zweiten Schaltgriffs 21, der gegenüber der in Figur 3 gezeigten Ausschaltstellung nach rechts geschwenkt ist.The contact arms 56, 57 of the movable contacts 52, 53 are each pivoted to the other fixed contact 62, 63. Furthermore, the other switch position is also shown by the position of the second switch handle 21, which is pivoted to the right in relation to the switch-off position shown in FIG. 3.

Figur 5 zeigt das Schaltgerät 12 gemäß Figur 2 in der Schaltstellung "Freiauslösung" im Längsschnitt.Figure 5 shows the switching device 12 according to Figure 2 in the switching position "free trip" in longitudinal section.

Bezüglich der Stellung der Kontaktarme 56, 57 der beweglichen Kontakte 52, 53 besteht bei dieser Schaltstellung kein Unterschied gegenüber der Schaltstellung "Aus", die in Figur 3 dargestellt ist. Jedoch ist aus Figur 5 zu erkennen, daß der zweite Schaltgriff 21 sich in der Stellung befindet, die der Einschaltstellung entspricht. Möglich wird dies dadurch, daß ein Klinkenhebel 76, der sich normalerweise in einer Verklinkungsstelle 77 an einem federbeaufschlagten Auslösehebel 78 abstützt, durch Verschieben einer S-förmigen Schieberplatte 80 ausgelöst wird und dabei den Kontaktarm 56 in Ausschaltstellung bringt.With regard to the position of the contact arms 56, 57 of the movable contacts 52, 53, there is no difference in this switching position from the switching position “off”, which is shown in FIG. 3. However, it can be seen from Figure 5 that the second control handle 21 is in the position which corresponds to the switch-on position. This is made possible by the fact that a pawl lever 76, which is normally supported in a latching point 77 on a spring-loaded release lever 78, is triggered by moving an S-shaped slide plate 80 and thereby brings the contact arm 56 into the switched-off position.

Diese Verschiebung der Schieberplatte 80, die zur Auslösung des Klinkenhebels 76 führt, wird vom Kupplungsglied 18 von dem angrenzenden Selbstschalter 11 auf das Schaltwerk 36 übertragen. In gleicher Weise überträgt das Kupplungsglied 16 die Kontaktbewegung vom Selbstschalter 11 auf das Schaltwerk 46. Unter Freiauslösung ist hierbei zu verstehen, daß die Einschaltung erfolgen soll, obwohl im Zeitpunkt des Einschaltens ein Uber-oder Kurzschlußstrom vorliegt, aufgrund dessen der thermische oder Magnetauslöser anspricht.This displacement of the slide plate 80, which leads to the triggering of the pawl lever 76, is caused by the coupling member 18 from the adjacent automatic switch 11 to the Transmitter 36 transmitted. In the same way, the coupling member 16 transmits the contact movement from the self-switch 11 to the switching mechanism 46. Free tripping is to be understood here to mean that the switch-on should take place even though there is an overcurrent or short-circuit current at the time of switching on, due to which the thermal or magnetic release responds.

Figur 7 zeigt die Seitenansicht des zweiten Schaltgriffs 21, der einen Körper 90 aus Isolierstoff besitzt, an welchem ein Vorsprung 92 angeformt ist zur formschlüssigen Verbindung mit dem Schaltgriff 22 des angrenzenden Selbstschalters 11. Im Inneren des zweiten Schaltgriffs 21 ist ein länglicher Hohlraum 91 vorgesehen, der als Führung für den bereits erwähnten Mitnehmer 94 dient. Der Mitnehmer 94 ist ein Blechstanzteil, das vorzugsweise wegen der geringen Kosten aus Stahlblech ggf. aber auch aus Kupfer- oder Aluminiumlegierung gefertigt ist, und hat im Längsschnitt die Form einer Kreisscheibe mit angeformten Stiel. Der Stiel dient als Führung im Hohlraum 91, während die Kreisscheibe mehrere Funktionen erfüllt. Zunächst ist die Kreisscheibe mit einer zentrischen Ausnehmung 99 zur Aufnahme der Schwenkachse 96 für den zweiten Schaltgriff 21 versehen. Die Ausnehmung 99 hat ovale Form und erlaubt so exzentrische Verlagerungen der Kreisscheibe. Dies ermöglicht ein Zurückgleiten des Mitnehmers 94 in den Hohlraum 91, der ferner eine Druckfeder 98 aufnimmt zur Baufschlagung des Mitnehmers. Eine am äußeren Umfang der Kreisscheibe des Mitnehmers 94 angeformte Rastnase 95 nimmt bei einer Schwenkbewegung des Schaltgriffs in Richtung Einschaltstellung die Drehachse 81 des Stellhebls 75 mit und bringt so das Schaltwerk 36 und den damit verbundenen Schaltgriff 20 des Signalschalterpols 35 in Einschaltstellung.FIG. 7 shows the side view of the second control handle 21, which has a body 90 made of insulating material, on which a projection 92 is formed for the positive connection with the control handle 22 of the adjacent automatic switch 11. An elongated cavity 91 is provided inside the second control handle 21, which serves as a guide for the already mentioned driver 94. The driver 94 is a sheet metal stamped part, which is preferably made of sheet steel, but possibly also of copper or aluminum alloy, because of the low cost, and has a longitudinal section in the form of a circular disc with a molded handle. The stem serves as a guide in the cavity 91, while the circular disk fulfills several functions. First, the circular disk is provided with a central recess 99 for receiving the pivot axis 96 for the second control handle 21. The recess 99 has an oval shape and thus allows eccentric displacements of the circular disk. This enables the driver 94 to slide back into the cavity 91, which also receives a compression spring 98 for loading the driver. A molded on the outer circumference of the circular disk of the driver 94 catch 95 takes the axis of rotation 81 of the actuating lever 75 with a pivoting movement of the control handle in the direction of the switch position and thus brings the switching mechanism 36 and the associated switch handle 20 of the signal switch pole 35 into the switch-on position.

In Figur 8 ist ein Längsschnitt durch den zweiten Schaltgriff 21 gemäß Figur 7 entlang der Schnittlinie VII-VII gezeigt, wobei erkennbar ist, daß der Mitnehmer 94 mittels zweier umgebogener Laschen 97 im Gehäusekörper 90 des Schaltgriffs 21 gehalten ist. Ebenso ist die Anordnung der Druckfeder 98 gezeigt, welche den Mitnehmer in Längsrichtung des Hohlraums 91, d. h. radial zur Schwenkachse 96 des zweiten Schaltgriffs 21 beaufschlagt. Für die Längsbeweglichkeit des Mitnehmers 94 sind ferner zwei Längsspalten 93 vorgesehen, die zur Aufnahme der Laschen 97 dienen.FIG. 8 shows a longitudinal section through the second control handle 21 according to FIG. 7 along the section line VII-VII, it being evident that the driver 94 is held in the housing body 90 of the control handle 21 by means of two bent tabs 97. The arrangement of the compression spring 98 is also shown, which the driver in the longitudinal direction of the cavity 91, i. H. acted radially to the pivot axis 96 of the second control handle 21. For the longitudinal mobility of the driver 94, two longitudinal gaps 93 are also provided, which serve to receive the tabs 97.

Im folgenden sollen der Aufbau und die Wirkungsweise der beiden Schaltwerke 36, 46 erläutert werden.The structure and mode of operation of the two switching mechanisms 36, 46 will be explained below.

Das Schaltwerk 46 für den Hilfsschalterpol 45 besitzt das Kupplungsglied 16, den Schwenkarm 72, der das Kupplungsglied 16 an einem Ende aufnimmt, und den Übertragungshebel 74, der am anderen Ende des Schwenkarms 72, der hier an einem Gehäusezapfen 70 schwenkbar gelagert ist, unter einem Winkel starr anschließt.The switching mechanism 46 for the auxiliary switch pole 45 has the coupling member 16, the swivel arm 72, which receives the coupling member 16 at one end, and the transmission lever 74, which is pivotally mounted on the other end of the swivel arm 72, which is pivotably mounted here on a housing pin 70, under one Angle rigidly connects.

Die Schwenkbewegung des Kupplungsgliedes 16, welche es beim Zusammenwirken mit dem angrenzenden Selbstschalter 11 bei dessen Auslösung ausführt, überträgt sich auf den Ubertragungshebel 74 entsprechend, wobei die Lageveränderung seines freien Endes, an dem die Verbindungsstange 59 angelenkt ist, die mit dem beweglichen Kontakt 53 verbunden ist, zu einer Schaltstellungsänderung des Hilfsschalterpols 53 führt.The pivoting movement of the coupling member 16, which it carries out when interacting with the adjacent automatic switch 11 when it is triggered, is correspondingly transmitted to the transmission lever 74, the change in position of its free end, to which the connecting rod 59 is articulated, which is connected to the movable contact 53 is, leads to a switching position change of the auxiliary switch pole 53.

Der Aufbau und die Wirkungsweise des Schaltwerks 36 ist im Vergleich zum Schaltwerk 46 umfangreicher. Daher soll anhand der in Figur 6 dargestellten Prinzipskizze hierauf näher eingegangen werden.The structure and mode of operation of the switching mechanism 36 is more extensive than that of the switching mechanism 46. Therefore, the principle sketch shown in FIG. 6 will be used to explain this in more detail.

Zentrales Schaltwerkselement des Schaltwerks 36 ist die bereits erwähnte Schieberplatte 80, welche durch ein Langloch 82 und einen auf der Gegenseite an die Schieberplatte 80 angeformten, in dieser Ansicht verdeckten und daher gestrichelt gezeichneten Führungszapfen 84 auf einer Kreisbahn um den Drehpunkt des zweiten Schaltgriffs 21 verschiebbar geführt ist. Das Langloch 82 umgreift einen Gehäusezapfen 71, während der Führungszapfen 84 in einem hier nicht gezeigten Gehäusespalt geführt, der beispielsweise durch zwei parallele Gehäusestege gebildet wird.The central switching mechanism element of the switching mechanism 36 is the slide plate 80 already mentioned, which is displaceably guided on a circular path around the pivot point of the second control handle 21 through an elongated hole 82 and a guide pin 84 formed on the opposite side of the slide plate 80 and concealed in this view and therefore drawn in dashed lines is. The elongated hole 82 surrounds a housing pin 71, while the guide pin 84 is guided in a housing gap, not shown here, which is formed, for example, by two parallel housing webs.

Ein weiterer Führungszapfen 86, der das Kupplungsglied 18 trägt, gleitet in einer kreisbogenförmigen Aussparung im Gehäusedeckel und verhindert so ein Verkanten der Schieberplatte 80, deren S-förmige Außenkontur dem gekrümmten Verschiebeweg in etwa entspricht.Another guide pin 86, which carries the coupling member 18, slides in an arcuate recess in the housing cover and thus prevents the slide plate 80 from tilting, the S-shaped outer contour of which roughly corresponds to the curved displacement path.

Abgesehen von der Schaltstellung "Freiauslösung" bildet die Verklinkungsstelle 77 gleichzeitig einen Drehpunkt für den Klinkenhebel 76, der über einen Stellhebel 75 mit dem zweiten Schaltgriff 21 verbunden ist. Die in Figur 6 gezeigte Schaltstellung entspricht der Einschaltstellung.Apart from the switch position "free release", the latching point 77 simultaneously forms a fulcrum for the latch lever 76, which is connected to the second switching handle 21 via an adjusting lever 75. The switch position shown in FIG. 6 corresponds to the switch-on position.

Mit Ausnahme der Freiauslösung schwenkt der Klinkenhebel 76 wegen der Beaufschlagung durch den Stellhebel 75 um die Verklinkungsstelle 77.With the exception of the free release, the pawl lever 76 pivots about the latching point 77 due to the action of the actuating lever 75.

Bei in Ausschaltstellung befindlichem Schaltgriff 21 befindet sich dessen Anlenkpunkt 81 für den Stellhebel 75 in größerem Abstand zum Klinkenhebel 76 als in Einschaltstellung. Aufgrund der starren Kopplung durch den Stellhebel 75 wird der Klinkenhebel 76 entsprechend nachgezogen und schwenkt um die Verklinkungsstelle 77. Dabei wird über den Übertragungshebel 58 der hier nicht gezeigte, bewegliche Signalkontakt 52, dessen Schwenkhebel 54, wie in Figur 3 gezeigt, in gleicher Weise wie beim Hilfskontakt 53 jeweils um einen Gehäusezapfen 41 gelagert ist, betätigt.When the shift handle 21 is in the switched-off position, its articulation point 81 for the actuating lever 75 is at a greater distance from the latch lever 76 than in the switched-on position. Due to the rigid coupling by the actuating lever 75, the pawl lever 76 is correspondingly retracted and pivots about the latching point 77. The movable signal contact 52, not shown here, whose pivoting lever 54, as shown in FIG at the auxiliary contact 53 is mounted around a housing pin 41, operated.

Bei Betätigung der Prüfeinrichtung 44, bei der die Schrägkante 64 den Auslösezapfen 66 beaufschlagt, wird die Schieberplatte 80 entsprechend nach rechts verschoben und drückt mit ihrer Auslösenase 83 gegen den Auslösehebel 78, wodurch die Verklinkungsstelle 77 den Klinkelhebel 76 freigibt. Hierbei dient der Anlenkpunkt 79 am Klinkenhebel 76 als fliegende Lagerung für den Stellhebel 75, um welchen der Stützarm 76 im Uhrzeigersinn verschwenkt und dabei über den Ubertragungshebel 58 ebenfalls den Signalkontakt 52 betätigt.When the test device 44 is actuated, in which the oblique edge 64 acts on the release pin 66, the slide plate 80 is correspondingly shifted to the right and presses with its release lug 83 against the release lever 78, as a result of which the latching point 77 releases the latch lever 76. Here, the articulation point 79 on the pawl lever 76 serves as a floating bearing for the actuating lever 75, about which the support arm 76 pivots clockwise and also actuates the signal contact 52 via the transmission lever 58.

Gleichzeitig mit der Verschiebung der Schieberplatte 80 wird mittels eines daran angeformten Mitnehmerzapfens 67, der im zweiten Schaltgriff 21 angeordnete Mitnehmer 94 beaufschlagt. Dabei drückt der Mitnehmerzapfen 67 gegen den Mitnehmer 94, wodurch dieser in den als Längsführung, vorgesehenen Hohlraum 91 im zweiten Schaltgriff zurückgleitet, so daß die an dem Mitnehmer 94 angeformte Rastnase 95 nicht zum Eingriff kommt und der zweite Schaltgriff 21 nach dem Entklinkungsvorgang in die Ausschaltstellung zurückgeht.Simultaneously with the displacement of the slide plate 80, the driver 94 arranged in the second control handle 21 is acted on by means of a driver pin 67 formed thereon. The driver pin 67 presses against the driver 94, whereby this slides back into the cavity 91 provided as a longitudinal guide in the second control handle, so that the locking lug 95 formed on the driver 94 does not come into engagement and the second control handle 21 after the unlatching process into the switched-off position goes back.

Der gleiche Vorgang findet bei der sogenannten Freiauslösung statt, wobei das Kupplungsglied 18 für die seitliche Verschiebung der Schiebeplatte 80 sorgt.The same process takes place in the so-called free release, the coupling member 18 providing for the lateral displacement of the sliding plate 80.

Die Drehachse des Anlenkpunktes 79 ist hierbei in einer kreisbogenförmigen Nut im Gehäuseunterteil geführt und legt hierdurch den Bewegungsablauf für den Klinkenhebel 76 und den daran anschließenden Ubertragungshebel 58 fest.The axis of rotation of the articulation point 79 is in this case guided in an arc-shaped groove in the lower housing part and thereby defines the sequence of movements for the pawl lever 76 and the adjoining transmission lever 58.
