Simple Touch Light Switch Circuit

This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according to the output signal of N1 gate.

When the sensor is touched this state is returned to the input of N1 gate and so there is a change of switching state.
