Me too, but there's often not so much spare metal available on microswitches, especially the small ones.

You can 'recover' them for awhile, provided you don't remove too much. Generally the contacts have layers, the top layer lasts longer. Once that is removed, the lower layer will 'wear' much more quickly.
The same is true for relays.
Whether is it worth the effort is a matter of choice. If you can't get a replacement, or the part is expensive etc. all come into the choice.
Never even bothered looking inside one, given how cheap they are. Assuming you can find an identical replacement, which can take some searching.
Sure, and sometimes there's less metal surface area too. That doesn't stop them working for years.
