Smitty,

"no AC in the area" meaning a complete circuit with a hot wire and a neutral
so I could run a transformer. I have two wires in the box but neither are a
neutral, so no complete AC circuit. The switch makes contact on the hot side
of a cirucit that runs on 120VAC, therefore I need a high voltage switch.

Think of this like light switch boxes in older houses where they didn't pull
neutral wires. Does this make sense now?

Got it, thanks for the clarification. I'm having trouble visualizing the
gadget and the problems associated with it. Isn't a reed switch a
"proximity sensor?" Why can't that work now? How about a micro switch?
What about a mercury switch? Or a battery operated emitter-detector with
relay?
