PURPOSE:To enable remote control and to avoid the reapplication of power supply at the restoration of power failure, by providing the auxiliary power supply switch and this control circuit. CONSTITUTION:When the switch 5 is closed, the auxiliary power supply circuit 4 is in operating condition and the start switch 13 is closed for a short time, and start pulse is out-putted to the control circuit 10 from the start pulse generating circuit 14. The relay drive circuit 9 is controlled with this control circuit 10 to close the auxiliary power supply switch 6 and to apply power supply to the main power supply circuit 2. After that, this auxiliary power supply switch 6 is switched with the remote control signal to the remote control reception circuit. Since the start switch 13 is not closed at the restoration of power failure, no reapplication of power supply is made. |
