Abstract

Cette invention concerne un procédé de commutation de plusieurs circuits, notamment des circuits de dispositif d'éclairage, dans un véhicule automobile. Selon ce procédé, on code plusieurs positions d'un élément de commande en binaire et on réalise le codage binaire d'une logique qui commande la commutation des circuits. Cette invention concerne également un commutateur conçu afin de mettre en oeuvre ce procédé. Ce commutateur comprend un élément de commande et un dispositif de commutation, ce qui permet d'obtenir plusieurs états de commutation en fonction de la position de l'élément de commande. Le dispositif de commutation est composé de plusieurs éléments de commutation présentant chacun deux états de commutation. On obtient ainsi un codage binaire des états de commutation de tous les éléments de commutation en fonction de la position de l'élément de commande, ce qui permet, par l'intermédiaire d'une logique, de commuter les circuits.
