Capacitance / Human Touch Switch Circuits
3 Way Touch Lamp: A three-way switch to control a lamp
(off-dim-bright, etc.) uses an NE555 Timer to generate a1-second
pulse, triggered by ambient ac fields that are picked up by the
human body. Read also the circuit description.

Touch Switch #4: This is achieved using a jugfet, it is a
very simple circuit and very effective to with a minimum
component count working via a 1.5v cell.
