Abstract

To reduce the rebound of the main armature with contact carrier in response to the switching operation of a contactor, magnetic-chamber base of contactor housing is provided with two support areas for the magnet yoke, said areas having different resiliencies. To this end, the magnetic-chamber base, designed so as to be capable of vibrating, has a supporting strip whose ends act as magnet-supporting areas.
