Claims

[Scope of utility model registration request]

An electrical device that can be remotely controlled using a remote control signal includes an AC power circuit, a main power switch that is inserted into this AC power circuit and can maintain an on/off state, and this main power supply. a sub power switch that automatically returns to the off state after being turned on in conjunction with the on operation of the switch; and a first switch for rectifying the alternating current voltage from the alternating current power supply circuit to supply direct current voltage to the electrical equipment. a power supply rectifier circuit, a switch means installed between the AC power supply circuit and the first power supply rectifier circuit, and a drive circuit for driving the switch means;
a storage means that outputs a signal for operating the drive circuit and stores the power on/off state and power standby state of the electrical equipment immediately before the AC voltage from the AC power supply circuit is cut off; a storage unit control circuit that controls the storage means by a control signal or a signal from the sub power switch; and a storage unit control circuit that rectifies the AC voltage from the AC power supply circuit to supply a predetermined DC voltage to the storage unit control circuit. A power on/off circuit comprising a second power rectifier circuit.
