Inventor: WASHIO TOSHIFUMI
IPC: G05F1/10
Filed: 1986-03-18
Abstract: PURPOSE:To prevent the malfunction of a load circuit by starting the circuit actuation after the normal load voltage is confirmed. CONSTITUTION:The direct current supplied from a rectifier 3 is applied to a load circuit 2 when a switch SW is closed. While a control signal transmitting means 1 monitors the load voltage to deliver no control signal for a voltage drop period set immediately after application of a power supply and to transmit the control via a line 10 signal to start the circuit 2 after confirming that the load voltage exceeds a reference voltage level. Thus the actuation of the circuit 2 is started.
