I was one of several who put some thought into this application.
The leading suggestion in my view, was the push to make, push to break
button, often seen for house lamp standards. These cost less than
relays. So one button, one relay, and you are set.
But you are tethered to a particular button design profile. if you were
looking for a uniform button profile to match others - this is not the
answer.
