Touch switch schematic electronic project

A touch switch sensor electronic project can be designed using this simple electronic diagram below. This touch switch sensor use one sense switch that allows shareholders "on / off". The capacitor C1 stores the switching state at the time. Depending on the signal output of gate N1, capacitor C1 is loaded or unloaded. On reaching the sensor, the signal is returned to the entrance of N1, so that switching state change occurs .
