ABSTRACT:
A relay with a moveable contact element which is actuated through armature movement transmitted via a slide is switched by the application of torsional forces to the movable contact element. The torsional forces are generated by the slide pushing the leaf spring contact element eccentrically in the region of one edge so that twisting of the contact element occurs during the switching event. A lower spring modulus for a spring of predetermined thickness and dimensions result so that a smaller magnetic system and a smaller overall relay is achieved given matching of the spring force curve to the magnetic system force curve.
