Definitions

  • the invention relates to an electrical switching device, in particular a monostable switch, such as. B. pushbutton or rocker switch, with a housing, with a manual actuating element arranged thereon for acting on at least one contact arrangement located in the housing, each consisting of at least one movable and one fixed contact piece.
  • a monostable switch such as. B. pushbutton or rocker switch
  • a housing with a manual actuating element arranged thereon for acting on at least one contact arrangement located in the housing, each consisting of at least one movable and one fixed contact piece.
  • Actuators are nowadays preferably provided for your actuation with such switching devices, which emulate the desired adjustment movement or adjustment direction, in order to thereby ensure that incorrect operations are avoided as far as possible. This is particularly advantageous if, due to the large number of adjustment options, a large number of electrical switching devices are to be provided, the assignment of which can otherwise only be recognized by means of appropriate labeling.
  • the at least one movable contact piece is designed as a contact rocker and has two contact arms on one, namely the same pivoting side, which work together with fixed contact pieces, which are each arranged opposite one another.
  • the housing has a recessed grip, which is provided with a drain opening through which impinging water can drain.
  • the housing according to a further embodiment of the invention has a peripheral edge which surrounds the contact arrangement.
  • the manual control element is designed and arranged so that it overlaps the edge and thus forms an overlapping barrier.
  • the drain opening in the recessed grip is at its apex, ie. H. at its lowest point, arranged so that water can run off without residue.
  • the drain opening is connected to a shaft-shaped channel which leads at least to an outlet opening arranged on the side.
  • the shaft-shaped channel is guided along outside the area surrounded by said edge, in which the contact arrangement is located. This ensures that water impinging on the electrical switching device cannot penetrate as far as the contact arrangement, since it is already drained through the drainage opening arranged outside the area surrounded by the edge, via the shaft-shaped channel connected to it, to the outlet opening.
  • the contact rocker is mounted in a floating manner in a contact bridge, the contact rocker being acted upon by a pressure piece which is resiliently mounted by means of a compression spring and which is guided in a longitudinally displaceable manner in the manual actuation element.
  • the pressure piece is arranged at right angles to the pivot axis of the manual actuation element, which in turn runs axially parallel to the tilt axis of the contact rocker. Accordingly, the manual operating element performs a pivoting movement when it is actuated, the direction of rotation of which is opposite to the pivoting movement of the contact rocker.
  • a preferred embodiment of the invention provides that the manual control element is provided with a lighting device, which for backlighting at least one Part of the actuating surface of the manual actuating element is used.
  • the lighting device can be a micro lamp or an LD light emitting diode. Regardless of whether the lighting device is provided as a microlamp or as an LD, it is provided for the electrical supply of the lighting device that it is connected on the one hand to ground and on the other hand to the movable contact piece. For this purpose, there is a connection of the lighting device to the compression spring, which acts on the pressure piece in the manual actuation element, both the pressure piece and the pressure spring being electrically conductive.
  • the lighting device serves to backlight a marking arranged in the actuating surface of the actuating element, which is preferably designed as an exchangeable symbol carrier.
  • the housing 12 has on its upper side a trough-shaped indentation which is referred to as a recessed grip and which, at its lowest point, depending on the point of view also to be regarded as a vertex, has an outlet opening 18. Below the trough-shaped indentation 16, the housing 12 continues in a cuboid shape and serves to accommodate a contact arrangement 20 which cooperates with the manual actuation element 14.
  • the drain opening 18 serves to prevent rain or splash water impinging on the electrical switching device 10 before it penetrates into the housing 12 and thus to prevent the contact arrangement 20 arranged therein from being impaired.
  • the drain opening 18 is connected to an underlying, transverse channel 19, which has outlet openings, not shown here, on both long sides of the electrical switching device 10, through which liquid which has entered the recessed grip 16 can drain off without having to carry current-carrying parts in Touch comes.
  • an approximately square opening 24, surrounded by an edge 22, is arranged in the trough-shaped recess 16 directly next to the drain opening 18, through which the manual operating element 14 with a switching part 15, which is arranged in the housing 12 in a pivotable manner, extends through the upper side of the housing, around the contact arrangement 20 to act inside the housing 12.
  • the manual control element 14 which covers the said edge 22 on all sides, so that the penetration of rain or splash water into the interior of the housing 12 through the through opening 24 is prevented, is provided with a lighting device 26, which in the exemplary embodiment shown is an LED light-emitting diode is formed, which is directed downwards at right angles to the top of the housing Switching part 15 of the manual operating element 14 is arranged.
  • This lighting device 26 is used for backlighting the operating surface of the manual actuation element 14, which is preferably provided with a marking and serves as an optical aid in the dark.
  • the switching part 15 has at its end facing away from the operating surface of the manual actuating element 14 below its pivot axis an elongated recess which extends coaxially to its longitudinal axis and in which a compression spring 28 and a pressure piece 29 are arranged, which is acted upon by the compression spring 28.
  • the pressure piece is dome-shaped at its outward-facing end and acts on a pivotable contact rocker 32 which is floatingly supported in a contact bridge 30.
  • This contact rocker 32 has two contact arms 33, 34 which, in contrast to known designs, are not arranged on both sides of the pivot axis as is customary, but connect at an angle to each other on one and the same swivel arm of the contact rocker 32.
  • the contact rocker assumes a corresponding pivot position in which one of the two contact arms 33, 34 is in contact with corresponding fixed contact pieces 35, 36.
  • FIG. 2 shows a top view of the electrical switching device 10 shown in FIG. 1, the same reference numerals already known from FIG. 1 applying to the same features.
