ABSTRACT:
An electromagnetic drive for a switch, preferably a motor protective circuit-breaker. The electromagnetic drive has a magnetic system, whose movable armature serves to actuate switching contact elements in the switch. The armature is coupled to a transmission lever by a leaf spring. One end the leaf spring is fixedly clamped and the other end of the leaf spring is connected to the transmission lever in such a way that the transmission lever is actuated when the leaf spring flexes and thus the free end of the leaf spring is displaced.
