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.
