Abstract

PURPOSE:To protect the circuit, by detecting the state of the control circuit and the circuit to be controlled, and cutting off the power input, if not in coincidence. CONSTITUTION:When the control circuit 6 is off, since the switching element Q2 is also off, the control element 4 is off and a current flows to the base of a switching element Q3 via a diode D1 and a resistor R5, resulting that the switching element Q3 is off and the input of the interrupting circuit 7 is at ''L'' level. Thus, no interrupting circuit 7 is operated. When the control circuit 6 is on, the control element 4 is also, to start the circuit 3 to be controlled for the operation. In this case, although the switching element Q2 is on and the input to the interrupting circuit 7 is once at ''H'', no interruption is caused because of its short time. If a failure is taken place when the control circuit 6 is off, the switching element Q3 is off, the interrupting circuit 7 is operated and the power supply switch SS1 is opened.
