Definitions
- the invention relates to a illuminated pushbutton a hollow cylindrical housing, one movable in it arranged hollow cylindrical plunger, a return spring, which is supported on the one hand on the housing and on the other hand on the plunger, and one arranged in the interior of the plunger Light element, especially an incandescent lamp.
- a generic illuminated pushbutton has been around for a long time State of the art. It takes place in the industrial area widely used. Such illuminated pushbuttons have a standardized external dimension, which in connection with the previous Design with one arranged between the housing and the plunger Return spring Measures to control heat generation required by the light bulb. It must be very heat-resistant and therefore expensive materials are used and / or the output of the incandescent lamp can be limited accordingly.
- the invention is therefore based on the object of a illuminated pushbutton of the type mentioned above with an optimal one Heat tolerance with regard to the inside of the ram to create lying light bulb.
- the object is achieved in that the return spring in Interior of the plunger lies. This makes it possible to To enlarge the inner diameter of the ram and thus a greater distance between the light bulb and the inner wall to reach the plunger. The one available for heat dissipation This significantly increases the area. Maximizing the Clearance between lamp base and housing wall and thus a higher permissible nominal operating voltage can be described by the Construction can also be achieved.
- the contact surfaces on a metallic housing to support the return spring electrically non-conductive.
- the end of the plunger Actuation button is attached, on which a sealing ring rests, which is a seal between the housing and the actuation button causes.
- a sealing point between the plunger and the actuating button lies in such a way that dirt is kept out as far as possible and so that cleaning the push button is simplified.
- the illuminated pushbutton 1 is essentially from a housing 2, a plunger 3, a return spring 4, an operating button 5, a sealing ring 6 and a lamp holder 7 assembled with a light bulb 8.
- the housing 2 is hollow cylindrical and has in the actuation area as usual on a front ring 9. Inside the case 2, the hollow-cylindrical plunger 3 is movable stored.
- the return spring 4 is supported in the interior of the plunger 3 and the housing 2 facing contact surfaces 10, 11 of the plunger 3 and the housing 2.
- the contact surfaces 10 are by inwardly directed projections 12 of the plunger 3 formed as molded insulating parts and consequently electrically non-conductive.
- the also electric non-conductive contact surfaces 11 are due to a diameter reduction at the bottom, i.e. facing the lamp holder 7 End of the housing 2 executed (see FIG 3). Because of this version it is possible with unchanged Size of the housing 2 to the inner diameter of the plunger 3 maximize, which brings significant benefits.
- the lamp holder 7 with the lamp 8 is on the actuation area end facing away from the lamp holder 7, the bulb 8 centrally in the interior of the plunger 3 is arranged.
- the bulb 8 is the use other light elements are also conceivable. Because of the enlargement of the inner diameter of the plunger 3 become problems related with undesirable thermal stress and insulation strength due to the existing air and creepage distances decreased. A possibly heat-favored warping of the im End area only tappet designed like a segment (see FIG. 2) 3 inside, which may be missing one here next to the lamp holder 7 arranged switching element could lead through the internal return spring 4 prevented.
- the actuating button 5 is at the end fastened a smooth bayonet connection 13 according to FIG. 2, which, in addition to a comfortable installation, is an angle-appropriate Stop for possible inscriptions on the actuation button 5 brings with it.
- the actuation button 5 for changing the bulb 8 is removable.
- One with you according to the current state of the art as required Sealing point between the plunger 3 and the actuating button 5 does not apply.
- the present sealing point between the operating button 5 and the front ring 9 is such that Dirt kept out as much as possible and thus the Cleaning the illuminated pushbutton 1 is simplified.
