Abstract

L'invention concerne un système de contacts pour chaque pôle d'un appareil commutateur pour basses tensions, comprenant un contact rotatif monté mobile contre l'effet d'un ressort dans un boîtier de rotor 4. Le système de contacts se compose d'au moins un corps de contact rotatif 1, 2 qui forme deux bras de levier 11, 12 avec chacun une extrémité de bras de levier et des pièces de contact 112, 122 sont disposées aux extrémités opposées des bras de levier 11, 12. Il existe des contacts fixes 5, 6 qui coopèrent avec la pièce de contact 112, 122 de chaque bras de levier 11, 12, chacun des bras de levier 11, 12 étant sollicité par un ressort 13, 14. Les ressorts ont un premier point d'appui à l'une des extrémités sur le corps de contact rotatif 1, 2 et un deuxième point d'appui à l'autre extrémité sur le boîtier de rotor 4. Il est proposé que le premier point d'appui d'un ressort 13, 14, à l'une des extrémités, se fasse par une action directe sur le corps de contact rotatif 1 et que les deux ressorts 13, 14 soient disposés sur un seul côté 111, 121 du corps de contact rotatif 1, 2. Une forme de réalisation préférentielle possède deux corps de contact rotatif 1, 2 qui sont juxtaposés et parallèles par leurs grands côtés.
