ECN Forum Forums General Topics of the Trade General Discussion Area Jamb Switch

Here is the Amprobe relay part number.
You can use those low-voltage roller type jamb switches with it if you have 120V at the fixture you want to switch.
Not cheap as I remember though, around $30.00 each.
You can download instruction manual at Amprobes website.
Hope it's what you need.

Model: RC-120S
Remcon Relay Switch
