Abstract

L'objet de l'invention est d'obtenir un pôle d'interrupteur à vide qui assure de manière précise et fiable pendant son fonctionnement le contact entre le contact mobile de l'interrupteur et une borne inférieure de courant, avec une structure rationnelle. Selon l'invention, le contact conducteur entre le contact d'interrupteur mobile (11) et la borne inférieure de courant (15) du pôle d'interrupteur à vide décrit est établi par un contact à frottement (12), agencé dans la plaque inférieure de contact (13) reliée à la borne inférieure de courant (15) par une pièce de traversée (14). La plaque inférieure de contact (13) repose sur une protubérance (6) du logement (2). Un tube d'écartement (8) monté sur la plaque inférieure de contact (13) maintient en position la plaque supérieure de contact (23). La plaque supérieure de contact (23) est fixée en position par un anneau torique (9) encastré dans une gorge (7) du logement (2). L'invention permet pour la première fois de mettre en contact de manière précise et faible le contact d'interrupteur mobile (11) avec une pièce fixe de raccordement de courant, c'est-à-dire la plaque inférieure de contact (13).
