ABSTRACT:
A movable magnetic armature of a size to nest within stepped faces on a fixed magnetic pole piece and on the armature support, respectively, is attached to the armature support by a conductive spring member which normally biases the armature away from the nested position in which it contacts a contact and stop member on the fixed pole. Imposition of the magnetic field causes the armature to move into closed contact position. The position of the armature even when in open contact position is close to the steps of the fixed pole piece as well as the armature support providing a low reluctance, short throw, quick action switch.
