Definitions

  • the invention relates to a pushbutton switch with two switch positions that can be assumed from a rest position by means of an actuatable rocker switch, in particular for the actuation of windows in motor vehicles, comprising a housing that also serves to accommodate switching elements, the switching elements having switching springs provided with switching contacts.
  • the object is achieved according to the invention in that the essentially flat switching springs are acted upon by actuating elements which are arranged essentially perpendicular to them and act as tappets and are articulated to the rocker switch.
  • the advantage of the push button switch designed according to the invention essentially consists in the fact that from the point of view of creating a high level of operational safety, i.e. a safe switching behavior, a simple structure could nevertheless be achieved, namely by moving the switching elements into a lower region of the housing, the switching elements being actuated by actuating elements acting as tappets from the rocker button, which can be arranged relatively far from the switching elements .
  • the switch or the switching elements can also be preassembled ready for operation, which is important for cost-effective manufacture, the remaining parts of the switch being able to be mounted in the manner of a modular system.
  • the actuating elements can be any insofar as they are suitable for bridging the free path between the rocker button and the switching springs, the actuating elements are advantageously designed in the form of flat plates, which can be produced in a simple stamping process, for example from metal, in a very simple manner.
  • the actuating elements are accommodated on two opposite sides in guides, which can be formed integrally with the housing, in a longitudinally displaceable manner, which in turn has the advantage that when mounting in the manner of a modular system, the plates are guided and an adjustment during assembly or a complicated assembly process is not required.
  • a particularly critical point in switches of this type are the actual switch springs, in particular when, as in the present case, very high currents are conducted through the contacts, such as occur, for example, when operating motors for lifting and lowering windows of the motor vehicles. For reasons of cost, these currents are passed directly via the contacts of the switches and not, as was customary in the past, via separate relays that are only operated with the buttons.
  • the currents from window actuating motors were passed directly via the switch contacts, it was found that they flung back and forth when the switching function was carried out, which inevitably led to an undesired alternating switching on of the motors and moreover, the contacts of the switch springs wear out very quickly.
  • the switch springs have an essentially rectangular, frame-shaped base, with a cross-sectionally wavy cross-section in the material-free inner region from a narrow side of the switch spring Jetty stands in.
  • This bridge ensures a suitably set pretension, the switching spring, so that a certain minimum pressure of the switching spring-side contacts independent of the actuating force of the rocker button is exerted on corresponding counter contacts when the rocker switch is actuated, as desired or as intended. This minimum pressure is sufficient to completely rule out the back and forth throwing of the switching spring which occurs in the known switches of this type.
  • a switch spring holder is gripped between the free end of the web and the other narrow side of the switch spring, the switch spring holder advantageously being held by two retaining means of the switch spring holder having latching devices.
  • the locking devices in the switch spring holder are advantageously formed by holding recesses of the switch spring holder which run essentially parallel to the switch spring.
  • the switch spring holder is connected in one piece to a plug device (contact tongue) which is led out of the housing, the other contacts on which the switch springs provided with contacts are active and in a passive state, through the housing on the side opposite the rocker button in the form of into a socket device insertable plug devices. All contact devices including the switch spring holder can thus be formed in one piece with plug devices or contact devices and emerge through corresponding holes provided in the housing to the outside.
  • the plug devices are advantageously surrounded by a jacket which is essentially parallel to them, the jacket serving on the one hand to protect the plug devices and on the other hand to guide the plug devices into a socket device.
  • a light element is provided in a bowl-shaped reflector which is open towards the rocker button in the region between the switching element and the rocker button, which has the advantage that the light element can be easily used even when the push button switch is installed, as well as the reflector and none separate expensive socket or socket needs to be provided for the lighting element.
  • a light emitting diode available in a wide variety of colors is very well suited as the light element, which has the advantage over conventional light bulbs that, with good luminosity, it has a very low power consumption and a very low power loss, i.e. unnecessary heat generation is avoided.
  • the switching elements themselves can be clipped or otherwise connected to the housing, for example Coat are surrounded.
  • the key switch 10 consists essentially of a housing 16, which serves to receive and hold switching elements 14, 15 in its interior, and a rocker switch 11, with which the switching elements 14, 15 can be actuated from a rest position into two end positions 12, 13 .
  • the rocker button 11 can be rotated about an axis 43 or corresponding bearings formed in the housing 16, which are not shown separately here.
  • the bearings are suitable holes essentially formed in a suitable location in the housing 16, into which corresponding projections which are formed in the rocker button 11 engage and which, like the bearings, are not shown separately.
  • the housing 16 is surrounded in the region of the rocker switch 11 and the switching elements 14, 15 by a jacket-shaped sheath 41 which can be connected to the housing 16 by means of clip connections 42. After the final assembly of the key switch 10, the jacket 41 is from above, see. Fig. 1, pushed over the rocker button 11 and locked with the aforementioned clip connections 42.
  • the clip 10 can be locked at a location, for example a console in the motor vehicle between the driver and front passenger seats, by means of clip springs 50, 51 which are firmly connected to the housing 16, so that separate fastening means are not required.
  • the lower area, ie the underside 37, cf. 1, the pushbutton switch 10 is plug-shaped, ie it has a plurality of plug devices 36 which are connected to corresponding contacts of the switching elements 14, 15 or are formed integrally therewith, which is described in more detail below.
  • the plug devices 36 protruding from the housing 16 on the underside 37 are, similar to the casing 41 surrounding the casing 16 at the top, surrounded by a casing 38 which is essentially parallel to the tongue-shaped plug devices 36.
  • the jacket 38 is integrally connected to the housing 16.
  • the number of plug devices 36 depends essentially on the number of circuits to be closed or opened in the first and second switching positions, ie switching elements 14, 15 can be defined individually as openers or closers or both.
  • At least one switch spring holder 30, 31 is arranged on opposite sides, which has two U-shaped retaining webs 34, 35.
  • the holding webs 34, 35 and the switch spring holder 30, 31 are integrally connected to the respective plug devices 36 belonging to them.
  • the holding webs 34, 35 have latching devices 32, 33 on their respective legs, these latching devices in the present exemplary embodiment being formed by notches which are formed essentially parallel to the bottom of the housing 16.
  • a switching spring 17, 18, which has a substantially rectangular frame-shaped base, is located in the latching devices 32, 33 or notches, cf. 3.
  • the switching springs 17, 18 are formed by suitably selected metallic spring material and represent a stamped part which is designed such that a web with a cross-sectionally wavy cross-section projects into the material-free or material-free inner region 25 from a narrow side 26. see. Fig. 2 and 3.
  • the free End 28 of the web 27 and the other narrow side 29 of the switching spring 17, 18 grips the switching spring holder 30, 31 in the region of the groove-shaped latching devices 32, 33.
  • the switching spring 17, 18 is replaced by a suitable choice and design of the wavy cross section of the web 27 it has been brought into engagement with the switch spring holder 30, 31, biased, in the direction of corresponding normally closed or working contacts 44, 146; 45, 147.
  • the normally closed or working contacts 44, 146; 45, 147 can also be formed integrally with corresponding plug devices 36 and protrude from the housing 16 in the direction of the underside 37.
  • a contact 19, 20 is attached, which with the aforementioned normally closed or working contacts 44, 146; 45, 147 comes into contact when an actuating element 21, 22 is actuated via the rocker button 11.
  • the actuating element 21, 22, which acts on the corresponding switching element 14, 15, is arranged essentially perpendicular to the latter, the actuating element, which acts as a plunger triggered by the rocker button 11, being articulated on the rocker button 11 and in guides 23, 24 is movable back and forth, which can be formed as part of the housing 16.
  • the corresponding articulation of the actuating elements 21, 22 formed here in the form of flat plates on the rocker button 11 consist of U-shaped rails 48, 49 which are arranged on the inside of the rocker button 11 facing the housing 16.
  • the side facing away from the rocker button 11 of the platelet-shaped actuating elements 21, 22 stands only on the essentially flat switching spring 18, 19, in the region between the two U-shaped retaining webs 34, 35 of the switching spring holder 30, 31.
  • the in the middle of the housing 16 facing a locking device 33 is compared to the outward facing locking device 32 in the vertical direction when looking at the Representation of Fig. 2 arranged offset downwards, so that the distance of the locking device 33 is smaller compared to the distance of the locking device 32 with respect to an imaginary housing base.
  • the inventive design of the switching spring 17, 18 does not hurl the free end of the switching spring 17, 18 with the corresponding switching contacts 19, 20, but with a certain minimum force the active switching contact 20 on the corresponding normally open contact 45, 47 and is held there, it is very easy to switch high electrical currents not only briefly, so that the push button switch 11 according to the invention, when used as a window lift switch for the windows of motor vehicles, does not require a separate interposition of power relays.
  • a lighting element 39 is arranged in a bowl-shaped reflector which is open towards the rocker button 11.
  • the respective actuation state of the rocker button 11 can be displayed via the lighting element 39, or the rocker button 11 can generally be identified when it is dark.
  • the lighting element 39 can be, for example, a light-emitting diode of any color or a miniaturized light bulb.
  • the rocker switch 11, the housing 16, the jacket 38 and the jacket 41 can be made of injection-molded plastic, for example also of glass fiber reinforced polyamide. In principle, however, any other suitable type of plastic with and without reinforcement is possible.
  • the actual switching springs 17, 18 are made of suitable metallic spring materials, for example spring bronze.
  • the contacts or plug devices 36, including those which are integrally connected to the switch spring holders 30, 31, consist of metallic materials, for example of suitable brass alloys.
