Hi Byron,

A "touch lamp" is a lamp that is turned ON and OFF by
touching ... usually a table lamp of some sort ... with the 
base / stand responding to the capacity of one's hand 
for the switching action.  Basically the lamp has a 
free-running oscillator that is "detuned" when the lamp
is touched, causing the switching action.  I'm aware of 
some that operate in the 80M range.

Once took a crew on a 400+ mile round-trip ... Montana's
a big state ... to respond to a ham's line noise complaint.
After much searching, involving switching off the power to
an entire block, and then to individual houses, found two 
touch-lamps in the bedroom of his parent's house next
door. (;-)

Some light dimmers are noise generators, also.
