Definitions

  • the invention relates to a push button switch that a has multi-part housing in which a push button is guided displaceably and a lighting device, an actuator and switching elements in the form of Microswitches are arranged, wherein when the Push button the actuator against spring force is moved and acts on the switching elements.
  • US-PS-4 504 713 is a modular design built push button switch with a the switching state signaling optical display become known.
  • the Push button switch consists of a housing module, a Housing cover module, a contact carrier module and one Lamp module. That from a lamp holder and a lamp existing lamp module is arranged on the housing module.
  • the Contact carrier module can be moved in the housing module performed, with fixed contacts on the housing module and Contact carrier module resilient contacts are provided.
  • a Pushbutton slidably guided in the housing cover module moves the contact carrier module against when actuated Spring force up to a stop, making contact made between the fixed and resilient contacts
  • the push button consists of a translucent Material, so that the lamp comes on by a Hole of the contact carrier module protrudes through the Contact can be observed.
  • On the housing module and on Housing cover module are overlapping cams with Holes are provided for receiving threaded bolts welded to a panel, for example for lifts are and serve to fasten the push button switch.
  • a disadvantage of this push button switch is that relatively large, especially by the lamp module conditional construction depth, so that it is for systems that only one small distance between panel and wall or one other limitation, cannot be used.
  • the great depth results on the one hand from the elongated Form of the incandescent lamps used, moreover, only one have short lifespan and sensitive to Vibrations are, so they are replaced more often must become what is time consuming and expensive.
  • the overall depth is pretty good complicated and expensive lamp holder, which for replacing the lamps from the switch housing has outstanding handles.
  • the signaling device is in a multi-part push button with this sliding lighting device intended.
  • the lighting device consists of a first circuit board arranged light-emitting Semiconductors, whose light has an annular shape Light guide to the bottom of the front of the Push button forming glass is directed. Of the The light guide runs along the edge of the glass, whereby the from Light guide not covered area of the glass with a opaque layer is covered, so that at Actuation of the push button as a light ring Acknowledgment message becomes visible.
  • the push button is in a calotte displaceably guided by means of a Snap connection is connected to a switch carrier.
  • a second one PCB attached, on which a microswitch is arranged.
  • a pot-like pestle of the push button acts on the switch button of the Microswitch on.
  • the microswitch is like this arranged that the switch button in the direction of movement of the Push button is moved. Since, moreover, the Lighting device, the plunger and the microswitch lie one behind the other in the direction of movement of the push button, there is a relatively large depth.
  • Other disadvantages are seen in the fact that two circuit boards are required are that have a flexible, multi-core conductor and Plug contacts must be connected, which causes the structure becomes more complicated and expensive.
  • no uniform illumination a push button can be achieved.
  • the invention is based on the object Propose push button switch according to the generic term, the does not have the disadvantages mentioned above and is built more flat and even Illumination of the push button enables.
  • the im Housing of the push button switch provided Lighting device four LEDs, which are about are arranged square on a printed circuit.
  • the switching elements in the form of microswitches and the Lighting devices are transverse to the direction of displacement a pushbutton slidably mounted in the housing arranged side by side. Take the microswitches a position in which the direction of movement an actuator and the moving device of Switch buttons of the microswitches at right angles to each other run.
  • the printed circuit and the microswitches are sandwiched between one flanges Lower housing part and an upper housing part clamped, the lower and upper parts of the housing are screwless are connected.
  • the advantages achieved with the invention are that with the special design of the Lighting device and its location to the Microswitches achieved a low overall height of the switch is, so that it can also be used in systems that have little space have behind the panel, can be used.
  • the vibration insensitivity offers further advantages and the long lifespan of the LEDs, therefore practically not replaced need to be reduced so that maintenance costs will.
  • This will further reduce the overall height achieved that the microswitch with its smallest Dimension running in the direction of displacement of the push button are arranged.
  • by redirecting the Switching movement Damage to the microswitch caused by strong knocks on the push button could be avoided. Due to the square arrangement of the Light emitting diodes will provide good illumination for both round ones as well as achieved with square snaps.
  • 1 is a lower housing part and 2 an upper housing part that has a square shape have the same size.
  • the lower housing part 1 is with provided a bottom 3, while the upper housing part 2 is formed only from side walls 4.
