Hey folks I want to have a hinged lid with some contacts capable of making only a few volts at low current. I want a overly large contact area to make with flat brass strip and the surface will be allowed to slide. I was thinking to use copper rivets like these with springs... Is copper a good choice or too soft and prone to tarnish?

Or would brass be a better choice?
