Touch Switch using digital IC

If friends seek touch switch Circuit model to be simple. I begs for to advise this circuit, use integrated digital circuit number IC CD4001 perform be Schmitt Trigger , and the integrated circuit IC 4020 perform be two divider circuit. It is control electric appliances work with Relay by when we touch at the sensor point for the first time On,when press for the second time will Off Relay. For other equipment nothing is a lot of request friends , see in the circuit better.

Touch Switch low cost by Timer IC 555

This Touch Switch circuit use a part compares with voltage 2 group , within the integrated circuit timer LM555 or NE555. For perform wait for catch the change of voltage , which be born from way leakage touches by change a finger. When the value is Resistance at drop the pate which build with pin 2 of the integrated circuit is valuable are down the level is Voltage output (pin 3). Will have the condition voltage high for apply the work and other circuit next. The detail is other , a friend sees in the circuit yes.

Touch Switch using UJT 2N3819

This be Very Simple Touch Switch Circuit. It used UJT 2N3819 is Main part numbers should set up this outside building circuit. When stay far from electric line or Power Line very much. Enough touch at infront touch 1 metal and 2 make Relay work ON get. When but urgent touch 2 metals only make Relay stop work OFF get. For within a building must enhance the part mends or infront touch 3 metals with follow circuit picture. The Relay use 6V to 9V sizes and Volt supply use 6V to 9V levels all right sir. Request friends have fun Touch Switch using UJT 2N3819 , please sir.
