Touch On-Off Sensor Switch Circuit Using 555 Timer IC

A tutorial on how to make a Touch On and Touch Off sensor switch using 555 timer IC on a breadboard. This circuit uses two pairs of touch conductors to sense and register the touch. One pair of touch conductors (sensors) for turning ON the output and the other pair for turning OFF the output.

You can use any output device like DC motors or AC appliances (like lights or fans) by using a relay at the output of 555 timer IC and by wiring the output device to the relay.
