摘要

P the switch according to the invention comprises a door - contacts with the lugs 6 for the coupling mechanism to a mechanical or electromagnetic, the door - contacts comprising for each function, a transverse opening for receiving a strip of the movable contact 16 is held in place by a washer assembly 22 which includes a central dish in order to keep the end of a spring 28, the assembly being such that the movable contact 16 can have a slight movement in the vertical direction at the moment of closing the contacts, but only to the opening of the gap between the contacts is limited so that the arc that burst of the fact of a short - circuit in the line is obliged to remain between the contacts in order to avoid damage to other parts of the contactor by the arc. Such a switch can be a unipolar, three-pole or bipolar, for example. / p
