Filed: 1986-12-23
Abstract: PURPOSE:To attain mass-production by connecting a thyristor to a gate of a FET and connecting a thyristor in parallel with a Zener diode, connecting the thyristor to a switching circuit and connecting an overcurrent sensing element in series with the switching circuit. CONSTITUTION:When a detection signal is outputted from a detection circuit 10, a switching element TR3 is cut off and the source potential of a MOS.FET 19 rises, a thyristor 12 connected in parallel with a Zener diode ZD2 is triggered and conducted, the switching circuit TR1 is conducted to drive the load through the reception. In such a case, when an overcurrent flows in the circuit of the AC 2-wire contactless switch, the overcurrent sensing element R4 detects the overcurrent. The thyristor 13 connected to the gate of the MOS.FET9 is triggered and conducted. The gate potential of the FET9 is fallen down nearly zero and the FET is cut off. Thus, since the voltage is not supplied from the FET to the switching circuit via the thyristor 13, the switching circuit TR 1 is cut off and the overcurrent is shut off.
