served to help keep them clean. Modern very low voltage/low current keying
Keys almost universally would have silver contacts. Silver is one metal
whose oxide is conductive.
The contact area is a high stress point of pressure, Gold is a soft metal
and actually can develop films that inhibit good conduction, unless the
contact wipes so as to be self cleaning.
My Bencher BY-2 paddle has gold-plated silver contacts. The contacts
don't wipe. The paddle is 21 years old. The contacts have *never* been
cleaned, and the paddle works great.

polish) contacts on modern keys might not be a good idea. He observed that
any abrasive rubbing or polishing might damage special finishes or alloys
that the manufacturer may have used on them.
