Pushbutton switch with magnetically coupled armature

An electrical switch comprising a substrate and at least one pair of spaced switch contacts arranged to be shorted by an electrically conductive armature, the armature having a central axis with first and second portions on either side of said axis terminating at first and second edges, a coupler layer disposed in spaced relation to the substrate, one of the coupler layer and armature being a permanent magnet and the other being made of magnetic material, the armature being normally held in a first condition by magnetic attraction between the coupler layer and armature, the switch contacts being formed on one of the facing surfaces of the substrate or coupler layer, the armature being movable by an actuating force to a second condition in engagement with the substrate, the armature being arranged to separate from the coupler layer by a double pivoting motion wherein an actuating force applied to the armature remote from the central axis causes one edge of the armature nearest the actuating force to break away from the coupler layer and pivot about the opposite edge of the armature until said one edge bottoms on the substrate, followed by the opposite edge of the armature breaking away from the coupler layer and pivoting about said one edge until the opposite edge bottoms on the substrate, the armature shorting the switch contacts in one of said first or second conditions and opening the switch contacts in the other of said first or second conditions.
