ABSTRACT:
A switch is connected between an input terminal and an output terminal. A determining circuit detects the voltage of the output terminal to determine whether or not the voltage of the output terminal is a predetermined voltage or lower. The determining circuit generates an output for turning off the switch when the voltage of the output terminal is a predetermined voltage or lower and for turning on the switch when the voltage is higher than the predetermined voltage. An impedance line is provided which is connected to the input terminal and to the output terminal so as to bypass the switch. When a supply of the power is cut off by the switch, a current flows from the input terminal to a load apparatus through the impedance line and the output terminal.
