On Air light relays

S

spacetrucker

I need some suggestions for relays for On Air lights. It's a Harris NetWave board and the AC wiring to the lights is about 10 feet from the board with plug in access to AC. I came in part way through this project and just trying to work with what was already in place with minimal reworking.
Thanks
 
Get a solid state switch, like this one from Hosfelt Electronics:

(scroll down the page a little)

Put this device in an outlet box and make your connections to the AC and warning light there. You may want to put some silicon grease on the back of the switch as it will run warm. Then run DC wiring to the console's warning light relay, and use a plug-in DC wall wart to power the switch. This set-up keeps the AC out of the counsel. Also means the console's warning light relay only has top switch low-voltage DC.

In my production studio, there was no AC near the warning light, so I used service mount metal troughs (there's a trade name I can't remember at the moment--it's the small U shaped stuff held on the wall with external clips) to run the AC up to an outside-type metal electrical box on the opposite side of the wall from the warning light (looks prettier than the usual handy boxes). Put the SS switch in that box, then used more surface mount stuff to run the DC wiring the opposite direction down to the console. A 12 volt wall wart runs the switch, it was scavenged from some defunct device.
 
There's also the venerable Hank box. Henry Engeneering makes a "Super Relay" that does everything for you (even flashes the light if desired) and all it needs is a simple contact closure from the board, which should be there if it's anything from the past 20 or so years.
