Waterdog,
Just a quick note that you may have already realized. To accomplish what you want with most of the relays suggested you must have a constant 120V to the relay & you control the relay thru the switch terminals. So if you remove the 120V control power to the relay the output contacts will open up immediately. The only manufacturer that I know of that makes a relay that would be a time delay off relay w/o constant control power is an
Agastat timer. They are expensive but very reliable.
I have learned this info the hard way. Good luck.
