Abstract

A switch includes a load switching unit inserted in a power supply line from a commercial power supply to a load; a control unit for switching a power supplied to the load by controlling the load switching unit; a first power supply unit for generating an operating power of the control unit; a second power supply unit for supplying a power to the first power supply unit in case the power supply to the load is stopped by the load switching unit being opened; and a third power supply unit for supplying a power to the first power supply unit in case the power is supplied to the load by the load switching unit being closed. An output voltage of the second power supply unit is set to be lower than or equal to that of the third power supply unit.
