Abstract
Discloses a switch for use with a circuit board for simultaneously closing one or more circuits. A switch cover mounts therein a reciprocable member whose permanent strip magnet carries one or more contact elements for circuit completion. The circuit board carries another permanent strip magnet. The strip magnets have consecutive, alternating polarities such that, in the closed position of the switch, the strip magnets have opposite attracting polarities, and such that, in the open position of the switch, the strip magnets have the same and repelling polarities.
