ABSTRACT:
An electromagnetic sensing device comprising a coil and a member magnetically coupled to the coil. An armature is movable relative to said member upon sufficient energization of the coil. A lever is carried by the member and is movable between first and second positions in response to the movement of the armature. The armature is operatively connected to the lever to move the lever on sufficient energization of the coil, whereupon a further mechanism coupled to the lever is actuated by the lever.
