Touch Switch
A touch switch is a switch that is turned on and off by touching a wire contact, instead of flicking a lever like a regular switch. Touch switches have no mechanical parts to wear out, so they last a lot longer than regular switches. Touch switches can be used in places where regular switches would not last, such as wet or very dusty areas.

Sir,
I want to know about basic of electronics.Even I have no idea of abc of electronics and in my course I have to study about circuits , logic gate with circuits.
Therefore , I request you to give me notes from basic.
Thanking you

First of all, this question is not specifically related to this circuit. Please use the forum.
Having said that I would like to suggest to buy yourself a book and start reading. There are numerous books about the subject that should get you started.

Plenty of places to buy this kind of stuff:
Radioshack
Conrad
Farnell
But I usually go to the local electronics shop.....
