ABSTRACT:
A pair of pivoted links positioned at opposite sides of a movable armature and reversely oriented with respect to each other, have a pivotal connection at their opposite ends to a movable contact carrier and intermediate their ends to the armature whereby movement of the armature is amplified in movement of the contact carrier to permit reduction in the air gap between the armature and electromagnet core without incurring a corresponding reduction in contact carrier movement.
