Presenting three ways to make a Touch Sensor Circuit along with a modified circuit - Touch Timer Circuit. Touch Sensor is a circuit which turns ON when it detects the touch on the Touch Pins. It works on transient basis i.e. the load will be ON only for the time the touch is made on the pins. You can also make a Touch Timer Circuit (by using a capacitor) which will allow the output to remain ON for some desired amount of time before turning it OFF.
