I think the OP wanted a 120vac coil.
I use something like the OP is trying to rig up. I use mine to turn on
my audio sytem whenever I turn on my cable box. Like the OP the outlet
on the cable box wasnt rated but for 100 watts. I have thought about
changing my setup to solidstate relays but have wondered if these may
cause a "noise" problem.

Yes. This relay has just that. Look at it.

Factory Mation is a good place for contactors and time delay relays.

Here's just what you need, for only $2.50:

http://www.allelectronics.com/make-a-store/item/RLY-482/120-VAC-40-AMP-RELAY/-/1.html

This one's rated at 40 A, so you should have no problems with it.

And forget Radio Shack, as some other posters have suggested. They're
useless.

That is a single pole single throw relay. Don't I need a double pole
single throw relay? Otherwise it'd be perfect.

I've had very poor luck with their stuff in the past. I only go there
when I'm desperate.
