Simple Touch Switch Circuit. Use 9v dc supply voltage to the circuit. The touch switch circuit can be activated by the skin resistance of the finger.
The indicated 4 diodes form the basic bridge diode network the thyristor is used for switching the mains 220v ac for the load while the ic m668 is used for processing the on off latching actions whenever the touch switch is touched. Use 9v dc supply voltage to the circuit. This is an effective easy simple and very interesting circuit.
Enough touch at in front touch 1 metal and 2 make relay work on getting.
Simple touch switch circuit to sense the touch event we don t need complex circuits or micro controllers we can sense the touch by using simple touch switch circuit using timer ic 555 here the touch switch circuit sense the event and makes output led glow and it remains in glow for few seconds and then becomes off condition. The indicated 4 diodes form the basic bridge diode network the thyristor is used for switching the mains 220v ac for the load while the ic m668 is used for processing the on off latching actions whenever the touch switch is touched. Touch switch circuit on off touch switch circuit using mosfet. Use 9v dc supply voltage to the circuit.
