ABSTRACT:
An electrical switch has a set of electrodes mounted on one side of a carrier. The opposite side of the carrier mounts an actuator having a plunger mounted for reciprocating motion. The plunger carries a coupler in the form of magnets. A conductive armature of magnetic material is disposed on the electrode side of the carrier. When the plunger withdraws the coupler magnets from the carrier, the armature is free to fall out of contact with the electrodes. A retention cover maintains the armature in the vicinity of the carrier such that subsequent movement of the coupler proximate the carrier will draw the armature back into contact with the electrodes.
