If friends seek touch switch Circuit model to be simple. I begs for to advise this circuit, use integrated digital circuit number IC 4011 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 [...]

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 [...]

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 [...]
