Abstract

L'invention concerne un commutateur électromagnétique (1), en particulier un contacteur, pourvu d'un interrupteur auxiliaire (2). L'objectif de cette invention est de réduire le surcroît de dépenses occasionné du fait que les interrupteurs auxiliaires utilisés pour former des contacts à ouverture et à fermeture sont de construction différente. A cet effet, un interrupteur auxiliaire selon l'invention fonctionne comme un contact à fermeture dans une première position de montage et comme un contact à ouverture dans une seconde position de montage, dans laquelle cet interrupteur auxiliaire est pivoté de 180° autour de son axe transversal par rapport à la première position de montage. Cet interrupteur auxiliaire (2) est de préférence exécuté de façon à permettre un montage aussi bien frontal que latéral.
