I soldered it out from an old mouse... but I think you will also get it on ebay

Peter Scholl -

This guy shows replacement switches fixing a newer version of same trackball(I think). It has a built in battery now.

Replacement switches he used from ALIEXPRESS.

I think I'll try those. I've had switches lose there mechanical springy-ness and also get where they don't work reliably on 2 or 3 trackballs.
