Abstract:
A switch operable under a predetermined condition includes a plurality of switch parts each including a pair of reed pieces and a connecting member of an electrically conductive non-magnetic material via which the plurality of switch parts are serially connected. The switch operates only under a condition where all of the plurality of switch parts are operated by external magnetic fields individually and simultaneously acting on the plurality of switch parts.
