Mike .. This has come up before, at least once. I think I’d try giving it a spritz of DeOxit and then working it a few times. One suggestion was to run about 1ma of dc current through it and switch it a few times to clean it. (I’m not sure I’d go that far, but it might work).
You can request the part number, price, and, I presume, stock status through the Support -> Parts Order From web-link, or just give them a call on Monday.
