Electronic Touch On Switch Circuit Diagram

This is a simple Electronic Touch On Switch Circuit Diagram. The Touch Switch circuit will detect stray voltages produced by mains voltages and electrostatic build-up in a room. This touch on-only switch can be triggered into conduction by electrical means, and can only be reset by way of a mechanical switch. When the touch terminal is contacted by a finger, the SCR turns on and illuminates LED1.
