Abstract

Résistance variable comprenant un élément résistant arqué disposé sur un substrat qui ferme un logement dans lequel est situé un support rotatif comprenant un balai destiné à entrer en contact avec l'élément résistant, et un dispositif d'engrenage à vis sans fin pour faire tourner le support. Le support 12 est en une matière thermoplastique élastique ou en élastomère, comporte des butées venues de moulage pour limiter la rotation du support, et des dents 16 cooperant directement avec la vis sans fin 13. Application : potentiomètres de manoeuvre.A variable resistor comprising an arcuate resistive element disposed on a substrate which closes a housing in which is located a rotary support comprising a brush for contacting the resistive element, and a worm gear device for rotating the resistor. support. The support 12 is made of an elastic thermoplastic material or of an elastomer, comprises stops formed by molding to limit the rotation of the support, and teeth 16 cooperating directly with the worm 13. Application: operating potentiometers.
