  • Another possibility is to use an extended wall connected to the pushbutton 18, such as the wall 19, for the second incandescent lamp . 13 to emit radiation emitted to the light guide 11 as a function of the position of the pushbutton 18, so that when the incandescent lamp 12 is switched off the second window 16 is illuminated as a function of the position of the pressure switch 18.
  • An advantage of the invention is, inter alia, that the light guide made of plastic serves at the same time for the insulation of the lead wires for the light bulbs 12 and 13.

  • Lateral support walls 30 of the windows 15 and 16 serve to increase the light absorption of these windows, since the luminous flux additionally captured by the walls is emitted through the windows 15, 16 ⁇ can. Furthermore, it is possible that the pushbutton 18 is provided with a projection which extends past the circuit board and into the vicinity of a base plate 26 of the base part 4, by which projection a switch mounted on the base plate 26 can be triggered directly by the pushbutton 18.

Abstract

L'invention concerne un module de commande pour commutateurs d'automobiles, comprenant plusieurs fenêtres lumineuses pour afficher l'état de fonctionnement du module, qui permettent également de repérer ledit module lorsque l'habitacle est dans la pénombre. L'invention vise à ce que ce module comprenne le moins de composants possible et qu'il soit facile à assembler. A cet effet, il est prévu un conducteur de lumière pour éclairer au moins une fenêtre, qui sert simultanément de cavité pour recevoir au moins une lampe à incandescence. D'autres perfectionnements avantageux concernent le fait de maintenir des courants lumineux, émanant de la lampe à incandescence fixée dans le conducteur de lumière, à l'écart dudit conducteur de lumière, ainsi que d'une fenêtre lumineuse, en relation avec la fonction d'un bouton-poussoir.
