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

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