I’m not necessarily discouraging eBay but many times the stuff isn’t what they say it is. It can be a great resource when you’re on a budget. Just remember the old phrase “buyer be aware” as it really suits the situation.Project requirements drive part specs and since you haven’t provided any details, there is little point in speculating.
FWIW, here is a DigiKey parametric search of the dual coil relays with contacts above 2 amps, sorted by price. These search tools are the easiest way to find a part for a specific application.
I looked through digikey which I have used before. Didnt find anything that seemed appropriate. I decided to draw a quick diagram. Can you look at the below and give any recommendations?
