description A switching device is provided that includes a switching mechanism unit and a switch drive control circuit. In the switching device, an operating member is maintained in an ON position by the sucking force of a permanent magnet and a yoke, despite the pushing force of a biasing unit, when the permanent magnet is in an ON position. The yoke is magnetized in such a manner as to reduce the magnetic force of the permanent magnet, when a coil wound around the yoke is energized by the switch drive control unit. The operating member and a switching member are moved from the ON position to the OFF position by virtue of the pushing force of the biasing unit, thereby shutting a feed line.
