PURPOSE:To attain ease of operation, by turning off a main power supply with a signal from a remote control transmitter. CONSTITUTION:Plugging a power plug in an outlet 7, and applying power by depressing a switch 8, an electromagnet 10 is energized and contacts (b) and (c) of a switch 11 are connected. The switch is turned off in releasing a finger but the switch 11 is self-held. In this state, the power is supplied to a remote control receiver 13 and when a signal 14a from a remote control transmitter 14 to turn on the power supply is transmitted, the remote control receiver 13 turns on a power relay 16 to supply the power to a circuit section 15. When a signal to turn off the main power supply is fed from the remote control transmitter 14 and the signal is received at the remote control receiver 13, the remote control receiver 13 changes the connection from d-f to e-f. As a result, the electromagnet 10 is deenergized, the switch 11 selects the a-c connection, and the power supply to the remote control receiver 13 is turned off. |
