Definitions

  • the present invention relates to a signal lamp whose housing has an opening covered with a translucent plate on the front, behind which plate there is a light-emitting diode which is mounted with a series resistor on a printed circuit board oriented transversely to the longitudinal axis of the housing.
  • Such signal lights are known and described, for example, in Swiss patent applications 6737/82 and 3194/83. With these signal lights, it is necessary to make an opening in the front panel of the mounting wall that corresponds to the size of the light housing. The luminaire housing is pushed into this opening until it clicks into place so that only an extremely thin front frame remains visible.
  • the present invention has for its object to change a device of the type mentioned in such a way that the assembly effort for the lamp is significantly less.
  • this object is achieved in that the side wall of the housing is closed and forms a continuous terminating edge on the rear, and that fastening means for fastening the housing to a control panel are present on the rear of the housing.
  • the invention has the effect that holes for the passage of the connecting conductors for the light-emitting diode are to be drilled in the front plate of the mounting wall only by means of a teaching.
  • the housing forms with a rear wall a plane which is coplanar with the end edge and which is covered with a self-adhesive layer.
  • connecting conductors can be pushed through the bore and the lights can be glued to the front panel.
  • the signal lamp can only be glued to the front panel of a control panel, which simplifies assembly.
  • the housing has a rear wall, to which at least one threaded bolt is fastened, parallel to the longitudinal axis of the housing, through which the connecting lines for the light-emitting diode are guided parallel to the axis, the luminaire housing can be fastened to the front panel by moving from the rear of the front panel to the Threaded bolt a nut is screwed on.
  • the back is also provided with a self-adhesive layer, the signal light is first glued on and then screwed on from the back. This is particularly advantageous for large front panels, since the installation can be carried out by just one person.
  • a flat and compact design The luminaire housing is achieved in that the rear wall of the housing is designed as a printed circuit board and the light-emitting diode is attached to it.
  • the present invention relates to an electrical push button switch with a light indicator, which has a switch housing and therein a longitudinally axially displaceable switch between a rest position and a working position and on the front forming the push button switch, in which switch slide a light emitting diode is arranged.
  • Such push button switches are described for example in DE-AS 1 290 620. They have the disadvantage that the switch slide carries a translucent plate on the front, which covers the light-emitting diode and thereby absorbs light, which makes it difficult to visually recognize the switching state of the switch.
  • the object of the present invention is to improve a push button switch of this type in such a way that the recognizability of its switching state is significantly improved.
  • this object is achieved in that the light-emitting diode forms the push button at the front end of the slide switch, and in that the switch housing on the front reverses the light-emitting diode cuff.
  • the invention has the advantages that a commercially available light-emitting diode can be used as a push button and light source and that the switch can be given a small overall height.
  • reference numeral 1 denotes the front panel of a mounting wall in which a signal lamp 2 is mounted.
  • the signal lamp 2 has a housing which forms a sleeve 3 which tapers conically towards the front and into which a rear wall 4 is latched at the rear.
  • the sleeve 3 forming the side wall of the housing is provided at its rear end with a circumferential edge 5 which lies in the plane of the rear of the rear wall.
  • a circuit board 6, which has spacers, is arranged in the housing parallel to the rear wall 4 elements 7 is held in parallel alignment with the rear wall 4.
  • a light-emitting diode 8 and two series resistors 9 are soldered onto the printed circuit board 6.
  • the light-emitting diode 8 has a translucent, cuboid-shaped jacket, which closes a round opening formed by the sleeve 10 ′ on the front side.
  • the rear wall 4 is provided on the back with a material-locking pin through which the two connecting conductors 12 for the light-emitting diode are guided.
  • a bore 13 is made in this. If the pin 11 has an external thread, the lamp can be clamped by a nut 14 screwed onto the pin 11 from the rear of the mounting wall 1.
  • the rear wall 4 is designed as a printed circuit board according to an exemplary embodiment, not shown, so that the lamp is lower by the thickness of the printed circuit board 6 and by the height of the spacer elements 7; is executable.
  • the same reference numerals designate the same or equivalent parts as in the example according to FIGS. 1 and 2, so that their repeated description is dispensed with.
  • the cross-sectional shape of the lamp housing is square in plan view in contrast to the round shape of the embodiment described above.
  • two pins 16 and 17 are provided on the back of the rear wall 4 instead of the pin 11, through which one of the two connecting conductors 12 is guided. If in this exemplary embodiment the lamp is to be fastened to the mounting wall 1 by means of a screw connection, it is sufficient if one of the two pins 16 or 17 is provided with an external thread and a nut 14 is tightened on this pin.
  • the rear surface 15 of the rear wall 4 can be provided with a self-adhesive layer and the light fixture can be glued to the visible side of the front plate.
  • the bores 13 can be carried out in a simple manner by means of a teaching.
  • the reference numeral 18 denotes the front end of a switch housing, which forms a sleeve in this area, which surrounds an opening with a guide 19, which can have a rectangular or round cross-section and into which a light-emitting diode 20 with its translucent Man tel protrudes.
  • the jacket of the light-emitting diode has a cylindrical or cuboid shape in accordance with the cross-sectional shape of the guide 19.
  • the light-emitting diode 20 is attached to the printed circuit board 22 and forms the push button of the switch, which can be pressed against the pressure of a return spring 23 from a rest position into a working position (or vice versa).
  • the part of the switch can be designed in a known manner, for example as shown in DE-AS 1 290 620. Because the light-emitting diode 20 is designed directly as a push button of the switch, the recognizability of the light-emitting display is significantly improved.
