Did you guys have a specific type of latching relay to use for controlling off/on states from either a momentary key or an intercom buzzer input?

I have a couple things I would like to control using the unused extra station outputs on my Melco intercom that is using LB buzzers.

Of course I could get new relays from mouser or digikey but I was curious if there were WE, Melco or other type specifically designed for telco installation that might look more at home on my backboard.
