Hey guys,
New to the forum...looks like some good info here.
I need some assistance. I have a circuit (12V) that energizes a light. When the light goes off or should I say, when the circuit is open, I would like to close a relay momentarily to deactivate a different switch. This switch is currently a momentary switch. Any ideas? I can make a drawing if that helps.
Many thanks, Brent

Just an update...
I got it working! The DEI 528T (pulse timer relay) allows me to pulse the timer circuit when the light turns off or when the circuit opens. Pretty cool little product. My only complaint is upon powering it up, it cycles on and off. I can live with that for now...
Anyway, just thought I would share the progress.
Thanks, Brent
