Where can I get a magnetic switch that runs off the accessory terminal of a cw 80 and is normally closed?

What do you want the switch to do.
Reed switches are magnetic.
Magnetic switch? Are you talking a relay or solenoid? Are you trying to impart some mechanical movement or close/open some contacts?
I have a gate with track on top and I want a light to go on when the gate is open and I want to power the lights from my ac terminal on the transformer.
Are the reed switches able to run on the ac terminal?
Thanks
The reed switch is just that, a magnetic switch. It doesn't care if it's AC or DC, only if the current is within it's rating, usually 1/2 amp for common reed switches. Sounds like it would do the trick for you with a little magnet to sense the gate position.
A thought occurs to me. You probably want to know if the gate is totally closed, or open to any degree, right? In that case, you'll need a NC contact that opens just when the gate is not in the fully closed position. Here's a reed switch that is open when the magnetic switches it, and closed at any other time. Connect a nice blinking LED or the like to it and you have the gate open signal.
