You can use a voltage trigger to latch a relay and provide contact closure.
I have a question as it relates to this. What, if any, difference does it make if the contact closure is eternal instead of momentary? Is it bad for the equipment? I have always used two separate relays from my controllers and program in the delays and often wondered if I could just use one relay, say, for a projector screen and use The NO side for up and the NC side for down.
