Abstract:
A switch (100) is provided with: an operating handle unit (1) installed on the front face; a control unit (5) which generates an output command signal on the basis of an operation with respect to the operating handle unit (1); and a power supply unit (8) which includes a first relay for switching connection and disconnection of a power supply input line, a second relay connected in series to the first relay, and a bypass resistance connected in parallel to the second relay, and which receives power supply from an external power supply and supplies power to an external load on the basis of an output command signal.
