Simple touch switch circuit with 4011 – source The circuit as you can see from its diagram is very simple and only uses 8 components. The heart of the circuit is the IC CD 4011 that is connected as a ...

This is a light switch or light activated relay circuit. The relay on when LDR uncoverd and relay off when LDR covered. Adjust VR1 for light sensitive. LED will turn on at the same time with relay.

Stop walking across a dark room to turn on the light. Install a 3-way switch and control lights from two locations.

Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.
