Abstract

A two-wire switching device includes a primary switching unit; a rectifying unit; a first power supply unit for generating a DC power while a power is stopped being supplied from the AC power supply to the load; a second power supply unit for generating a DC power while the power is supplied from the AC power supply to the load; a stabilizing unit; a control unit for starting an operation of the second power supply unit when an electric power is supplied from the AC power supply to the load; a secondary switching unit for short-circuiting the output terminals of the rectifying unit while the second power unit is operated; and at least one auxiliary switching unit. The auxiliary switching unit is on during a time interval from output terminals of the rectifying unit being short-circuited to the primary switching unit being turned on.
