This circuit uses a 4011 logic gate digital as the bases of the touch switch.
It are Standard and very easy because I used a Gate of IC 4011.
In circuit at pin 2 of 1/4 IC is Hi logic “HI” alway.
If touching the plate connected to the 2 numbered,so logic output is Hi ,but don’t touching
is Low logic.
The 22M resistor on pin 1 causes the the circuit to be very sensitive to the touch.
