Electrical switching device, in particular time switching device

The present invention relates to an electrical switching device, in particular a timer, with a housing composed of at least two parts, in which the puncture and / or movement group pen including a switch device with at least one switching element are installed, the at least comprise a subassembly housed in a housing part.

Electrical switching devices, such as. Time switches, and above all staircase time switches, have so far mainly been equipped with larger housings, which, depending on their use for switch panel installation or surface mounting, were either designed completely differently or equipped with different assembly parts, e.g. _e at the foot end. In the course of the development, whereby such devices are to be installed in the smallest possible housing of the form similar to the modern circuit breakers in the narrow design according to a standardized divider for panel mounting, the housings have become steadily smaller, so that an obvious construction is ever narrower There were limits.

This initially gave rise to the problem that either an optimal assignment of the subgroups in such a switching device and a possibly necessary adjustment is impossible or an appropriate one Division of the housing, which would be desirable with regard to the accessibility of the subgroups, not achieved can be. However, with the development of the market towards the smaller housings in standardized divider sizes especially the functional division into an essentially hood-shaped and another part gained great importance, the type of assembly aids provided is also very important.

To a group of electrical switching devices The ones that have already been mentioned belong to those that are perhaps best representative of the relationships Timers ^ L. Among these, the staircase time switches are of particular importance in the practical engineering of electrical installation won. These staircase time switches usually consist of an electromagnetically driven

709829/0427 " ³ "

NEN armature and a thereby actuated escapement, which is brought into a working position, from which it returned to the rest position after an adjustable time.The time-dependent circuit to be switched is thus closed with the activation and excitation of the electromagnetic armature system or indirectly engages the switch means or the Hemmwerk is coupled correspondingly to said switch means _o Because of the installation regulations such Zeitsehaltgeräte are installed in a substantially fully enclosed housing, which necessarily consist of two parts or more parts, eg. a hood-shaped housing part with a removable cover, usually in the so-called shell construction, and the walls of which are penetrated by the electrical connection parts to which the outer circuit parts, such as network, consumers, key switches, indicator lights or the like. be connected.

As üemmwerke (pneumatic-mechanical) devices have proved as well as electronic circuits in practice to be good at the both purely mechanical IN QUESTION time switching equipment, pneumatic, although from the standpoint of costs so far, the pneumatic Hemmwerk ^ ^ost Advantages has. As a purely mechanical escapement mechanisms are known, which, similar to clockworks, preloaded by.die electromagnet armature group, ie. be pulled up, the running time is adjustable, after which a rocker arm movement causes the jerky switch-off

In both the pneumatic and the purely mechanical escapement mechanism, the switch device is in this way by means of a lever with tilting properties or

- 4 -709829/0427

Similar elements of the mechanics are coupled with the mechanically moving parts in such a way that the predetermined time Duty cycle is ended by a switching process that is as abrupt as possible; the switching element for the time-dependent switching of the consumer circuit is either from the escapement or from the electromagnet armature group actuated.

Electronic escapements usually consist of a circuit arrangement with an RC element and cold cathode tube, which also causes the circuit toggle, and then work for example. with an alternating voltage Heiais with two working positions or another bistable Relay together. Recently there have also been purely electronic circuits whose switch-on time has passed an adjustable counter circuit is preselected and a simple high-voltage relay can be used. In addition to the electronic escapement mechanisms, there are also devices based on the Birnetall principle, possibly with several strips arranged one behind the other, the deflections of which add up, must be taken into account.

With all time switches of the relevant type known to date and available on the market are the individual components in the housing, e.g. with screws, individually mounted or simply inserted without special position securing, which is why a considerable working time is necessary for the production and the relevant Workers must have specialist knowledge, as they each have to do the exact adjustment and adjustment must pay attention to during assembly, if the operational reliability is not to be endangered. These coining gain a downright vital importance if that Time switch housed in a relatively small housing, such as. - as already mentioned - in a form similar to the modern circuit breakers in the

709829/0427

Narrow construction according to a standardized divider for panel mounting (e.g., with a width of 17.5 mm) should be designed.

The present invention is therefore based on the object of designing the individual components of the time or other electrical switching device so that they are forcibly assigned to one another when they are introduced into the housing and tolerances of the individual geometric dimensions are either automatically, ie. can balance without special measures, or at least not interfere with the function of Z _e itschaltgeräts. An important detail is that the abovementioned jerky lever movement or other jerky switching will be set and maintained with sufficient timing. In connection with the new type of construction, the assembly is supposed to be simplified accordingly and both by this and by additional individual marks, ie. through simplifications or additions to the components themselves, manufacturing costs can be saved.

Within the scope of the above-described, more general problem on which the invention is based, it is also that the switch device or the interacting with it or the associated individual components of the electrical or time switching device are to be designed in such a way that they are self-contained by the introduction in the housing, insofar as it is practically feasible, are forcibly adjusted, as set out above more general case the larger components. Here naturally have the same conditions as the automatic compensation of tolerances, the jerky lever or switching process also in this narrower case the same meaning

The problem on which the present invention is based finally includes that at a division of the housing into a substantially hood-shaped rope and one substantially as a foot part Serving part of the latter is to be designed so that it is in connection with the hood-shaped part brings about a support and fit assignment of built-in parts and thus also the fulfills a more general task or supports the effect of the improvements already mentioned. In addition for this purpose, the foot section is intended for both panel mounting as well as for surface mounting of the electrical or time switch device.

In the most general sense, the task described above is one of the type described at the beginning belonging electrical switching device solved in that a subgroup housed in a housing part to these with regard to their space requirements Determining dimensions adapted so that they are at most approximately smaller by the wall thickness of the housing are as the corresponding dimensions of the housing and / or can be positively inserted into this housing part is.

The basic idea of the invention is that the compulsory assignment of the assemblies of the electrical switching device either by structural union of subgroups - as in the case of the practical matching dimensions - and / or brought about by form-fitting pluggability in other components shall be. For this new technical teaching of the invention there are basically several ways that are separated, ie. independently or in combination:

In practice, the basic concept of the invention described in this way can be supplemented appropriately by that in an electrical switching device under discussion here, its function and / or movement groups have a Electromagnet-armature group and an escapement of mechanical and / or electronic design, an associated thereby

"actuated switch device with at least one switching element, possibly in a switch block for include the time-dependent circuit to be switched, as well as electrical connection parts, the spatially adapted Subgroup by the electromagnet armature group and / or the switch device and / or the connecting parts formed and the spatial adaptation by the subgroup and / or the housing part assigned in one piece molded spacers and / or shaped pieces are brought about.

In a further embodiment, a function and / or movement group, eg. the cylinder-piston group, assembled so that it is a fixed part of the housing, e.g. the cylinder in this way, and a functional part movably guided therein, for example. containing the piston and the housing-fixed component with a housing part, ZB is _0, cohesively united integrally to the upper part structurally. In this case, it is also advantageous if the one-piece structural union is brought about by the fact that the parts in question are at least partially identical and several functions as ^ parts of the functional groups and / or bearing elements for parts of the movement group and / or holding elements and / or as ^ Serve housing parts. In particular, this applies when a function and / or movement group comprises a movably guided function part _e is formed wegungsgruppe by a bearing in a bearing piece levers a B, wherein at least part than this as a bearing element and / or bearing piece Part of the housing and / or serves as a fitting for other components.

The invention already conveys in the above-described basic form, including with

- 9 709829/0427

some of the features described with regard to the Purpose of your object compared to the state of the art - apart from the ones already solved by this Task achieved advantages - the leaps and bounds of technical progress, that a compulsory assignment and adjustment takes place automatically and thus design and production paths are opened up that previously required the cost-effective installation of assemblies of the electrical Circuit technology and the associated electrical engineering nik in a relatively small housing with prescribed maximum dimensions, among other things. because of the minimum size of individual Sealed independently as a unit of components was.

So it is through the basic invention thought achievable technical progress in a time switch whose inhibitor is of pneumatic design and consists of a cylinder-piston group with air cushion, sealing valve and adjustable air outlet and / or whose electromagnet armature group contains a plunger armature, promoted in a special way, if the cylinder of the cylinder-piston group and / or the electromagnet, ie. with one with a diving anchor, its Coil body with winding fixed part of the housing and the piston or armature or plunger armature movable guided functional part of the relevant positively insertable subgroup is (are).

In the practical implementation of these features, it is then advantageous that the inner diameter the pipe wall and / or the length including the base of the cylinder of the cylinder-piston group in connection with the diameter and / or length of the bobbin of the Electromagnet armature group is at most approximately equal to an internal dimension of the housing (are). This is how it becomes

- 1o 709829/0427

It also enables the adjustable air outlet opening to be space-saving and, above all, also simplified in terms of manufacturing technology, in that the adjustable air outlet opening is a hollow valve body with a threaded spindle, which is embedded in the bottom of the cylinder of the cylinder-piston group in a form-fitting, one-piece manner and adjustable through the housing · the front "- described features come in a still further embodiment then into action when the pipe wall and / or the bottom of the cylinder of the cylinder-piston group at least partly as the one part such as _e serves ingredient of the upper part of the housing and / or is structurally united in one piece with parts, preferably a wall of the housing (»are).

In any particular combination of individual or several features essential to the invention exist the achievable advantages more or less mainly in the fact that the space requirement - because multiple occurring parts - pieces are united in one piece according to one of the essential inventive ideas - in an optimal way to the given circumstances, ie. Limit dimensions can be adjusted. This has the further advantage that the electrical or time switching device can be completed properly with simpler tools and thus Can be produced more cost-effectively than is possible with previous designs; the focus of the Technical progress is therefore largely due to the substantial simplification of the manufacturing process. Technology.

The features of the pluggable design of Components, first of all the bobbin of the electromagnet-armature group and / or a bearing piece of a lever

- 11 709829/0427

a movably guided puncture part and / or a Holding piece, for example, the switch block of a switching element of the switch device and / or connecting parts in a form-fitting manner in other component (s) and / or in a part of the housing, e.g. the upper part is designed to be plugged in are, and optionally additionally bobbin and / or bearing piece and / or holding piece or switch block from at least two plug-in parts to each other and to another part, for example. the housing positively assembled are »Finally, according to the invention, this is supported by a subgroup molded stop approach the distance to another subgroup is mutually maintained.

This principle of the combined plug-in mounting, which is also essential to the invention, can be further developed Embodiment particularly advantageous in a device for the optional blocking of a switching element Switch device in one of its switching positions, specifically mechanically and separately adjustable, in particular for optional permanent switching, i.e. with a staircase time switch for optional permanent light switching, realize when the device contains a rocker arm, which is in the blocking position with an arm, a switching element the switch device regardless of the operating position the puncture and / or movement group concerned, e.g. applied to the electromagnet armature group and on an axis integrally formed there connecting two parallel walls of the one housing part from the outside the intermediate wall of this housing part can be inserted protruding through and through one on the opposite side molded half-hub shell is mounted so that it is through a between a groove of the rocker arm and a Holding slot in one between the said parallel Walls of one housing part form-fit from the

- 12 709829/0427

opposite side inserted retaining piece clamped toggle spring pressed against the axis and bistable preloaded will.

The basic with this device in connection with the actual subject of the invention basic features achievable technical progress in the sense of the task according to the invention of an automatic compulsory mutual assignment and adjustment of components of the electrical switching device is even increased if stops for the rocker arm on the one hand by a groove in the end piece of a contact spring of the acted upon by him switching element of the switch device and on the other hand by an edge of a housing fixed Partly are formed; this is especially true if there is a contact spring of the switching element at the free end is equipped with a fitting plugged onto it, preferably made of insulating plastic, the one Groove for guiding the arm of the rocker arm, which acts on the switching element during blocking, and this groove on the side of the free end of the contact spring have a delimiting wall which serves as a stop.

As above in the immediate connection to the basic solution of the higher-level The object underlying the invention is set out on the basis of a list, the basic idea of Furthermore, the invention can also be supplemented by the fact that the spatially adapted one accommodated in a housing part Subgroup is a switch device with at least one assembly to which a bearing piece in which the Pivot axis and by means of this the shift lever is mounted and / or a switch block belongs (belong) in which the switching element is held. In the case of a timer with one electromagnet armature group and one

SO 2600A09

A mechanical and / or pneumatic type of inhibition belonging to the functional and / or movement group is then expediently the shift lever one coupled to the electromagnet armature group and / or the escapement Assigned to movement group.

In practice, this group can be subordinated to the above-mentioned basic idea of the invention essential features by two different main types of measures independently or in combination. One is that the switch block as assigned on both sides, namely the switch lever and the housing or its upper part Spacer and / or shaped piece is formed. The other main type is the switch lever with its pivot axis stored in a bearing piece, which as both sides, namely the pivot axis and the housing or its Spacer and / or shaped piece assigned to the upper part and / or at least partially between parallel walls of a part, e.g. of the upper part of the housing positively is designed to be plugged in from the outside. Both cases are based on the common principle that teti-et is a construction group the switch device and / or a part of the housing in one piece with spacing assigned on both sides. and / or fittings are equipped and in this way the switch device can be plugged in and form-fitting is automatically and compulsorily designed to adjust and hold in the part of the housing »

In all of these cases - both individually and in combination - is essential to the invention Special features - the object of the invention described at the beginning has already been fundamentally achieved by the assembly work on mere plugging together without there being any special, ie. additional adjustment or fastening

- 14 709829/0427

demand, are limited. With regard to the "intended use of the subject matter of the invention, in its previously described variety of embodiments compared to the state of the art, the sudden progression is achieved that without the previously necessary costly effort of special workers and their working time and without additional material costs only for the adjustable fastening of the Components, namely automatically the necessary accuracy and stability of the spatial assignment of subgroups of the electrical or time switching device, especially in the particularly critical subgroup of the switch device - due to the necessary volatility of the switching processes - is achieved _{e In} addition, it is achieved by the basic idea of the invention makes it possible to noticeably reduce the space required by the assemblies of the electrical switching device also by means of the group of features essential to the invention described last, and the associated problems to achieve savings.

In a further embodiment, the bearing piece is at least two parts, ie. from an upper part with one as a half hub and a lower part with one as other half hub for the swivel axis serving groove on End, positively assembled and the pivot axis of the shift lever is mounted in the two half hubs. Included it may be expedient that the lower part is additionally guided in the upper part so that it can be plugged in and / or that the lower part of the bearing piece structurally combined in one piece with the switch block. After all, with this combination of features essential to the invention, an optimum of production-related simplification is achieved, if part of the bearing piece with a '^ part of the housing or instead is structurally integrated in one piece with the switch block «,

- 15 709829/0427

The basic idea of the invention is particularly effective when the above-described features essential to the invention in a time switch device individually or more or less combined are recycled, whose inhibitor is of a pneumatic design and thus a cylinder-piston group with air cushions, Sealing valve or sealing washer and adjustable air outlet opening and its electromagnet armature group contain a plunger, especially if the gear lever has at least two arms, one of which (one) Contact spring (s) of the switching element acted on one side and the other acted upon by the piston or plunger will. The technical progress that can be achieved in this way can be increased by the fact that the arms of the Shift lever unequal length according to the contact spring loading and the full piston movement of the escapement required strokes are measured, whereby a further reduction of the space requirement and / or adaptation to the given .room conditions of the switchgear achieved will. An additional simplification also in this sense is achieved if one on the gear lever Cam mounted on an axis parallel to the pivot axis and against a stop on one side, preferably against the rest position, is biased by a spring, especially when the axis of the cam with the pivot axis of the shift lever is identical. The assembly is simplified to a particular degree, if then also the two-sided of the shift lever protruding stub of the pivot axis have different diameters and the diameter of the camps are adapted.

Both in connection with the previously described features essential to the invention - and then in highest possible degree - as well as regardless of it, ie. used separately, the task according to the invention is further-

709829/0427

Mn solved and a technical advance achieved while meeting the current high quality requirements through a particularly economically producible construction if the switch block is made of spacer molded parts for the contact springs so that it can be inserted between two parallel walls, possibly with guide grooves and / or guide lugs, is also advantageous it is when the switch block contains at least two contact spring groups , which are acted upon by the shift lever, preferably by means of different arms, in stages, because so electrical auxiliary circuits for a temporary connection or disconnection of circuits, for example. for the excitation of the electromagnet can also be applied. The interaction of the shift lever and contact springs is additionally supported if at least one contact spring is equipped at the free end with a molded piece, preferably made of plastic, with molded sliding surfaces for the shift lever arm and / or another lever; This special feature also serves to implement the general basic idea of the invention and the simplification of the production and the reduction of space requirements aimed at or achieved with it.

This fundamental idea, which is essential to the invention, is the formation of a second main group of the electrical Switching device, namely the switch device, as a plug- bare subgroup conveys the surprising possibility of both the structure of the electrical switching device, or in special application x'all of the time switch in every respect space-saving as well as the assembly work ie, to design cost-effectively and thus to manufacture the device in a particularly economical and technically reliable manner, as well as either to develop further areas of application at all or to substantially increase this development

support financially. After all, it is of considerable advantage here if the plug-in upper part and / or lower part of the bearing piece and / or one of the spacer molded parts of the Switch blocks with a stop lug and / or a groove for plug-in mounting of other components of the switch device or another assembly of the electrical or time switching device and / or for the additional automatic Centering are equipped with another housing part. With the help of these other special features it is possible to turn the manufacture through further savings in manufacturing aids or at least to make their simplification even more cost-effective «

The basic one already described above with regard to its main variants in the form of an overview Invention concept of the compulsory assignment of the assemblies of the electrical switching device either through structural union of subgroups and / or through form-fitting pluggability in other components In the case of an electrical switching device, at least one subgroup of its function and / or movement groups is housed in a G-housing part, thereby particularly expedient according to a third main group of utilize essential features of the invention if the other G-ehäuseteil a foot part with an insertion opening for a resiliently pretensioned tab for attachment to a Support rail, e.g. according to DIK "46 277, which is suitable for a hood-shaped housing part.

A further embodiment is achieved when the aforementioned foot part - preferably on the hood-shaped housing part facing away from the side - both for the guidance of the resiliently pretensioned tab as well as, optionally, for the form-fitting reception of a tab—

709829/0427 - 18 -

shaped board with mounting hole, especially the Long hole shape, for surface mounting of the electrical switching device is formed and guide rails "or guide grooves for the fitting support of the hood-shaped housing part having.

In a particularly expedient form, this basic concept of the invention is "realized when as a tab a tab-shaped plug-in part with a rear Serves nose for the mounting rail, which can be inserted in different positions and in one Position positively locking by means of a stop and a spring tongue which is preferably integrally formed in one piece rigid and in the other for attachment to the mounting rail certain position resiliently gate by means of a compression coil spring between two stops freely is kept happening.

The subject of the invention serves in a further development of its basic idea and the technical port step achievable through its utilization, if the foot section has one on one side of the insertion opening preferably integrally formed web, around which the plug-in part in the locking rigid position by the stop and the spring tongue is clamped on both sides and / or if the insertion opening has grooves, its cross section the spring tongue of the tab happens unrestrained in its resiliently held position. Come in detail the above-described features essential to the invention come into play when the plug-in part is in two order 18o ° offset layers can be inserted into the same insertion opening and the stop or web on one, preferably facing away from the hood-shaped housing part Side of the insertion opening and on the opposite side grooves for the free passage of the spring tongue.

709829/0427

are brought «.

Compared to the housing designs known from the prior art, the one described above provides an erratic technical port step in that - as it should be according to the underlying task should - the assembly of the entire switchgear both inside the housing and for the attachment of the sub-assemblies is much simplified, but still more reliable. Plus that is part of the job met, according to which in a simple manner both a surface-mounted Montoge as well as a control panel installation on a mounting rail, for example. according to DIN 46 277 should optionally be possible, and this condition is also met, although there are practically no additional parts that could be lost, but in both cases the same parts can only be used in different types of installation.

In the case of a switching device with functional and / or movement groups, at least one in the hood-shaped Housing part include so housed sub-group that they face the hood-shaped housing part The inside of the foot part, the advantage of the special features essential to the invention is then increased, if on said inside grooves and / or projections and / or noses for the fit-retaining Acceptance of the subgroup positively and cohesively, preferably are attached in one piece «if an electromagnet-armature group is part of a function and / or movement group belongs, it is particularly useful if the grooves and / or projections and / or lugs mentioned exist in an annular groove with an annular web for the coil body of the electromagnet armature group. In other cases, e.g. if a switch device with a switch block for a function and / or movement group

holding switching element for the circuit that may be switched in a time-dependent manner is increased Success is achieved when the switch block by means of a nose attached to it in parallel webs at least one of two parallel walls is inserted in a form-fitting manner. Both of the last mentioned are essential to the invention Special features can of course also be implemented and combined with advantage be recovered.

In Iig, 1 a Ms d, circuit diagrams are shown that are typical for time switching devices; Fig.ia and b relate to time switches with an electronic escapement, while Pig.1 c and d require a mechanical or pneumatic escapement (cf. target.

In Fig, 1a the power supply network, for example. from an alternating current source, connected to lines 1 (phase) and (zero), which are used by the actual consumer circuit, the lamp 3 in series with the work switching

2G00409

contact 4 bridging relay is actuated by relay 5, that, in series with a protective contact 6 of the usual type and the key switch 8, also in a branch between the lines 1 and 2 and is of the type of a changeover relay with two windings and an additional one Impulse contact 7 is. In parallel with this, the non-linear resistor 9 is attached to a current limiter long pressing of the button is used, and the indicator glow lamp 1 ο.

After pressing the key switch S, the normally open contact 4 is closed, so that at the node 11 voltage is applied, whereby the fixed 12 and the adjustable 13 resistance, as well as the rectifier 14 the capacitor 15 more or less depending on the setting charging slowly. When the ignition voltage is reached, the capacitor 15 in series with the second winding 16 switching diode 17 connected in parallel, this is ignited and the capacitor 15 via the second winding 16 discharged; thereby the changeover relay 5 is out of his mechanical locking in its initial position, ie. the switched-off state of the normally open contact 4 is returned. So that the RC charging circuit (capacitor 15 with resistors 12, 13) always has the same defined initial state of charge has, the capacitor 15 is in each case when the relay 5 is energized by the additional pulse contact 7 and the resistor 7a are discharged to the extinction voltage of the switching diode 17, as indicated by the dash-dotted line Line 18 is indicated.

Significantly less complex than the circuit of Fig.1a is that of Pig.1b, because there the cost-consuming Relay 5 with two windings and pulse contact by a simple one that is functionally equivalent to this Retentive relay 19, e.g. a latching relay with elec-

Ig.1a: the consumer (the lamp 2o) is in Series with the working contact 21 of the remanence relay 19, whose mechanical coupling is indicated by the dash-dotted line Line 22 is indicated, between the lines 23, 24, which lead to the alternating current source, not shown. at Actuation of the key switch 25, to which an indicator glow lamp can be connected in parallel, charges the phase voltage on the line 23 via the rectifier 26, the adjustable resistor 27, and the winding of the remanence relay 19 and those of these parallel resistors 28, 29 (the latter again of the non-linear current limiting type) and finally the rectifier 3o the capacitor 31. Exactly as in the example of Pig.1a, this is at When the ignition voltage of the switching diode 32 is reached, it is discharged via this and the winding of the ßemanenzrelais 19. There now the current flows through the winding in the opposite direction, the remanence relay 19 is in its idle state returned, ie. unlocked and the normally open contact opened. The "delay time" is set at the adjustable Resistance 27 preset.

In the circuit examples of Pig.1 a and b As can be clearly seen, the circuit parts belonging to the RC groups 32 and 33 are the actual electronic ones Inhibitors. No further explanatory explanations are required that and how this is time-dependent acting electronic escapement by purely electronic, eg. on the basis of pulse counting circuits, or can also be replaced by those whose circuit control function, as already mentioned, is different from others Sizes than the time is determined or influenced.

The rocker arm 135 with its slot bearing 141 is mounted on the axle 142 in such a way that it can be inserted from the outside and then the housing wall, the cover 129, located between the two parallel walls 143, 144, only one of which is visible of the upper part 112 protrudes through. In addition to the arm 136, the rocker arm 135 is also guided by the Sieviunru ^ fsnase 145 with the end wall 146, which is formed on the inside of the cover 129. The axis 142 is formed on the walls 143, 144 and connects them. on it the rocker arm 135 is mounted with the half-hub shell 147, which is formed on the slot bearing 141 _{or the like}

of combinations of the essential features of the invention conducive if at least one subgroup, preferably part of the housing, e.g. the top 112 of the housing is made of a transparent material. In this case it can also be useful if other sub-groups, which serve as a bearing piece or as a guide piece or as a holding piece, also made of transparent material are made.

In the following, the switching device 12o with the switching element 121 is primarily described with reference to Pig. 3 in its complete interaction with the lever 115 serving as a switching lever. Since the various operating positions are crucial here, these are shown separately in FIG. 3a for the rest position, in FIG. 3b for the working position shortly before and in FIG. 3c after the engagement. The ezugsziff ^ em identical to those of FIG _e 2 a to d, so that a repetition of the description was unnecessary parts already mentioned and described parts are

The pivot axis 235 of the shift lever 115 is in the bearing piece with the upper part 2-36 and the (dashed drawn) lower part stored 2-37 and contains in addition to the already mentioned guide head 116 on the longer Arm 238 the shorter arm 239 with the curved one

When the circuit of the winding 1o3 is closed by pressing a button, the plunger 1o4 is drawn into the interior of the coil former 1o2, the pretensioning spring 1o5 being compressed and the piston 1o8 being pulled down in the cylinder 1o7, the air cushion 1o9 being pulled through the sealing washer 11o is filled, and an outflow of the air cushion due to the valve action of the sealing washer and the small air outlet opening 111 initially prevents _(e Fig 3b). The guide head 116 and with it the switching lever 115 with its shorter arm 239 are pivoted clockwise about the pivot axis 235 by the piston 1o8 and the head plate 118. The shorter arm 239 slides with its curved sliding surface 24-0 on which is plugged onto the contact spring 24-4 of the switching element 121 fitting 245 along and suppressed by this, so that the current circuit of the consumer is closed against the other contact spring 246 ₀

As soon as the contact spring 244 is deflected far enough by the shorter arm 239, the cam 241 jumps under the bias of the spring 248, which can be seen in Figure 3b, also clockwise until it stops 249 abuts against the shorter arm 239 (FIG. 3c). From now on, the cam 241 slides when the air cushion Io9 through the piston 1o8 under the action of the pretensioning spring 1o5 through the adjustable air outlet opening 111 depending on whose released cross-section is pushed out more or less quickly, along the molded piece 245 clockwise, the piston 1o8 and the switching lever 115 slowly returning to their rest position (FIG. 3a). Only when the cam 241 comes to rest with its upper edge 25o below the lower edge 251 of the fitting 245, the contact spring 244 jumps into its rest position - namely jerky - back

The short arm 242 of the switching lever 115 "actuates in the working position, ie" with the maximum stroke of the piston 1o8, the idle switching element 243 and thereby opens the excitation circuit of the winding 1o3 of the electric magnet armature group 1o1 (if it is still activated by the pressed button is closed), so that the winding can not be overloaded even after prolonged pressing the button 1o3 _e the operation of the Iluheschaltelements 243, which can also function in a different manner as a protection circuit, takes, as can be seen, only a relatively short time during a ' ^ part of the stroke of the piston 1o8, namely as long as a downstream connection may be excluded.

In Pig _o 4, the switching lever (115 in FIGS. 2 and 3) is shown separately in the swiveled-out position of the cam 241 (a) and in the rest and final working position - except for the absolute angular position - (b).

The pivot axis 235 is on the side of the shift lever 115 with a stub 253 "of larger diameter, and on the other hand equipped with a stub 254 of smaller diameter, on the latter of which the squat 241 with the spring 248, which is integrally combined with it and rests on the pin 255, is mounted (Figo4c). The different diameters of the pivot axis 235 on both sides facilitate assembly, because this creates a risk of confusion or of the Reversal of sides is excluded. The spring causes the cam 241 to move against the shorter one in the rest position or in the final working position by means of the stop 256 Arm 239 pressed with the curved sliding surface 24o and on the return of the shift lever 115 from the shorter one Arm 239 taken away. With the cam 241 of the short arm 242 is united in one piece, so that this first of all delayed deflection and then the slow return of the shift lever 115 participates

The switching device 12o with the switching lever 115 and the arrangement of the switching elements 121 or of the quiescent switching element 243 in the switch block 252, as can be seen without further ado, the invention in a much simpler and nevertheless reliable manner Task that the jerky lever movement and thus switch actuation is set precisely enough in time can be and is adhered to, with two sub-groups being forcibly adjusted by being introduced into the housing and tolerances of the individual geometric dimensions either automatically, ie “without special Compensate measures or at least not interfering with the puncture of the switching device or timer can affect,

The compulsory assignment and adjustment of the subgroups can be clearly seen with the help of Fig. 5, where the switch block 252 from the two standard spacer parts 257, 258 with the slots 259 to 262 for the contact springs not shown here can be plugged together between two parallel walls 265, with guide grooves 265, 266 or corresponding guide lugs of the switch block can be inserted in a form-fitting manner is (see Fig. 5c) “The two spacer moldings 257, 258 are unmistakably forcibly assigned to one another by the pins 267, 268 in the blind bores 269, 27o and the upper part 112 of the housing by means of the stop strips 271, 272 ", which are integrally combined with its walls,

The last-mentioned assignment is determined by the one-piece combination of the switch block 252, ie. in Figure 5b of the spacer molded part 257 with the lower part 237 of the bearing piece with the half-hub shell 273 for the pivot axis, not shown, of the shift lever (115 in FIGS. 2 and 3) and, on the other hand, by the likewise

The lower part 237 of the - ^ agerstücks for the pivot axis 235 is in a corresponding slot with the upper half-hub shell 275 of the upper part 236, ie. between the webs 276, 277 and with it the switch block 252 additionally forcibly inserted centered and thus switch block, switch lever and housing as well as electromagnet armature ^ ruppe again forcibly each other assigned without the need for special adjustment O

The same purpose serves the projection 278 on the switch block 252, with the additional fit between the side walls and lugs in the other part of the housing, not shown, is brought about. In the end are on the two spacer Pormteile 257, 258 - also laterally symmetrical - stops 279, 28o for a Contact spring and stiffening walls 281, 282 for: Stop lug 274 and the lower part 237 of the bearing piece attached in one piece, which is also again for accuracy make a significant contribution to the assignment of the subgroups of the switching device or timer.
