摘要： A magnetic switch assembly for an electrical circuit includes a switch housing with a cavity formed therein and at least one magnetically attractable electrical contact member exposed within the cavity. One or more electrically-conductive magnetic pole members are movably disposed within the cavity, with a magnet being secured to the pole members for movement therewith. The pole member or members and the magnet are movable in the cavity between a first position in electrical contact with the contact member in order to complete electrical continuity of the electrical circuit, and a second position spaced away from the contact member in order to break electrical continuity of the electrical circuit. A movable and magnetically attractable striker member is disposed for movement toward and away from the switch housing cavity, such as on a pivotal or hinged accessory cover. The magnetic attraction between the magnet (and pole members) and the striker member moves the pole members and the magnet into the second, circuit-breaking position whenever the striker member is moved within a predetermined distance from the cavity.
