Standard Touch Switch by Gate of IC 4011

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.

Simple Touch Switch One Shot by 4011

Here is a simple touch control switch, I use IC 4011.
Logic HI at output is timer pulse delay control by C1
1S = C1 4.7uF(micro farad),
After touching the plate connected,so well pulse output.
Detail more, Please read in this image circuit.
