they have limited quantity of NEW FACTORY NOS switches for sale at $3.50 each.
NOTE: These are the switches ONLY --- NOT the chrome caps OR white spacers---
These will get you gonig if cleaning won't cure some dead ones

Is it not conceivable that you could desolder them and then soak them in isopropanol for a few days?
FWIW, I've repaired sealed switches before in this manner (from a DW8000). After letting them soak for a while, I kept them submersed and then repeatedly clicked them dozens of times, watching until the tiny air bubbles weren't getting released any more, letting me know their innards were thoroughly filled with the isopropanol. After letting them soak for about a day, and then drying them out (including fervently clicking them a bunch to prompt the release of any of the iso in them), I soldered them back in and they worked fine.
