ABSTRACT:
An electro-magnetically controlled apparatus is provided having in a box an electro-magnet adapted to move an armature subjected to the force of a return spring developing an initial force, a contact holder associated with the armature and presenting side by side a plurality of pairs of housings each comprising a lower housing close to the armature, and an upper housing placed above, a plurality of mobile reversible bridge contacts, respectively placed in the respective housings and each receiving the action of a pressure spring which urges them against a cross piece separating two housings of a pair, these bridge contacts being adapted to cooperate each one with a pair of fixed reversible contacts disposed in the case so as to form one of the possible configurations of opening or closing switches placed in power or signalling circuits. The contact holder (9) comprises four pairs or superimposed housings (10.sub.U --11.sub.U, 10.sub.V --11.sub.V, 10.sub.W --11.sub.W, 10.sub.X --11.sub.X).
