Many thanks for the detailed writeup, mnem! Wasn't aware refurbishing the micro-switches was a thing or how they looked inside, I just stole the right buttons from dead mice to have a bag of replacements so far. ::)

For silver tarnish removal an eraser does wonders, without removing any of the underlying silver.

You want to remove some of the silver, to remove the divot (wear crater) and make the contact flat again. As you can see in the pic, there's more than enough material to do this several times. This leaf spring is made of thin hardened brass, so pretty fragile; trying to rub it with a pencil eraser hard enough to remove anything is much more likely to mangle it than do any good.

Yeah, I usedta keep a bin of deaders in my office at the ISD to rob cords, switches, scroll wheels, etc off of. But I found that A) I could often service the switch while on the ticket using just what was in my Little Bag of Dirty Tricks™ in less time than it took to walk down there for a replacement and 2) Once I knew how to do it, was literally less hassle than desoldering the switch most of the time, and C) I still had that as a back-up plan.
