Definitions

  • Push-button switch with light-emitting semiconductors as the light source for elevators the light of the light-emitting semiconductors arranged on a printed circuit being directed as a confirmation message onto a translucent push button, a light reflector being provided for light control and carried by an adapter.
  • a light-emitting element with light-emitting semiconductors for push-button switches is known from DE utility model G 90 15 115.1.
  • the head part of the push button switch there is an annular light guide connected to a printed circuit board, which guides the light from the light-emitting semiconductors integrated on the printed circuit board to the front of the push button, a light ring being visible on the operator side as a confirmation message.
  • the light-emitting semiconductors also called light-emitting diodes, are regulated by means of photo semiconductors depending on the ambient light, so that the brighter the ambient light, the brighter the visible light ring.
  • a disadvantage of the known device is that the light emitted by the light-emitting diodes on floors of an elevator system with high illuminance is only insufficiently visible on the push button.
  • Another disadvantage is the complex manufacture of the circuit board connected to the light guide.
  • a push button switch according to the preamble of claim 1 with a cubic housing has become known, in which the movement of the push button is transmitted to an adapter and from this to a switch.
  • a printed circuit with light-emitting diodes is arranged in the adapter, the light of which is directed to the push button by means of a reflector arranged in the adapter.
  • Elastic conductors are connected to the movable adapter by fixed connection pins located in the switch base.
  • the printed circuit is connected to the elastic conductors by means of spring contacts.
  • a disadvantage of the known device is that the movement of the push button is transmitted to the adapter and from there to the switch.
  • the printed circuit and the light emitting diodes are moved, which can lead to mechanical stress on the sensitive printed circuit board and the light emitting diodes.
  • the elastic conductors and the spring contacts are mechanically stressed with every push of the button.
  • Printed circuit boards, light-emitting diodes, elastic conductors and spring contacts become more susceptible to faults.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of creating a push-button switch in which the acknowledgment message generated by light-emitting diodes appears on the push-button with incandescent lamp illuminance.
  • 1 designates a cover plate with an opening, not shown, through which a closure ring 2 enters, into which a push button 4 provided with a lens cap 3 is inserted on the rear.
  • Plunger 5 of the push button 4 penetrate an existing adapter 6 and actuate a switch (not shown) carried by a switch block 7.
  • a light reflector 10 consisting of a base 8 and a reflector part 9 is inserted into an opening 11 of the adapter 6, the light reflector 10 resting on an outer shoulder 12 on the adapter 6.
  • a printed circuit 13 with light-emitting diodes LED1 ... LED5 and diodes D1 ... D4 is so far immersed in the base 8 of the light reflector 10 until it rests on an inner shoulder 14.
  • the supply voltage of the diode circuit is supplied to the printed circuit 13 by means of connecting wires L1; L2.
  • the light-emitting diodes LED1 ... LED5 arranged on the printed circuit 13 penetrate the light reflector 10 in bores B1 ... B5 and protrude into the reflector part 9 provided with a bevel 15.
  • the centrally arranged bore B5 is surrounded by a beveled elevation 16.
  • Adapter 6 and switch block 7 are held by carrier bolts 17 and nuts 18 arranged on the cover plate 1.
  • carrier bolts 17 and nuts 18 arranged on the cover plate 1.
  • cylindrical, cubic or other shaped light reflectors 10 are used.
  • the push button 4 is made of translucent polycarbonates with a white tint.
  • Light-emitting diodes LED1 ... LED5 are provided as light sources, which, for example, emit light with a wavelength of 590 nm. Green, red or other colored LEDs LED1 ... LED5 are used as required.
  • the electrical circuit diagram shown in FIG. 5 shows a series circuit of light-emitting diodes LED1 ... LED5, which are located on a bridge branch of a bridge rectifier formed by the diodes D1 ... D4.
  • the other bridge branch is connected to the connecting wires L1; L2, to which the supply voltage of up to 120 V AC is applied.
  • bridges are provided if not all diode locations are equipped.
