Abstract

La présente invention concerne un potentiomètre à curseur optique. Un tel potentiomètre comprend à l'intérieur d'un boîtier 21 et sur un support 25 une résistance variable à commande optique comprenant une couronne photosensible 2, la valeur de cette résistance variable dépendant de la position d'un spot lumineux sur cette couronne. Une lampe 27 est fixée à un capôt solidaire du boîtier 21. Cette lampe 27 envoie un faisceau dans une partie creuse de l'axe 22 du potentiomètre. Ce faisceau est défléchi par un système prismatique 29 solidaire de l'axe 22 pour éclairer une partie sélectionnée de la couronne photosensible 2. Application à des potentiomètres de grande durée de vie et à faible couple.
