Fathom, Medusa and Centaur use them also. The oldest Bally I ever saw them on was a Six Million Dollar Man. That was surprising as they are usually 44 type. Every one in my Medusa works fine. They seem to work ok until the internals start to corrode and they no longer work. There's metal on metal contact inside the housing. After the corrosion starts, they can't be repaired.

I always replace them with 44 type when doing swaps and I guess the main reason for that is no one produces these any more.
