Simple Touch Switch

This is a simple touch schema diagram.I think you can use this for many purposes.I have used this schema as a security schema device.Here I have used very common Transistors   2N 5458 N and 2N2222 to gain the signal .2N3906 Transistor work as a switch here.







Note 
# Build this schema on a PCB
# Use a copper plate to touch senseer 
# Dont supply more than12V
