The circuit that will be introduced can be used to control the lighting lamp and auto door, and it can also be used to burglarproof alarm. This circuit consists of the inducting electrode plate A, regulated diode VS, FET transistor VF, music integrated circuit IC, transistor V, relay K, diode VD, resistor R1 and R2, potentiometer RP and power supply switch S, etc, see as the figure. The inductance controlled switch circuit By adjusting the potentiometer RP, the music time of the IC can be changed, so the lighting time of the lamp can be changed.
