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

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.
