Unscrew 5 screws, which are partially hidden. Three screws are located under the rubber buffers and one in the battery compartment under the sticker (which should then be loosened beforehand).

You can simply push the blue trackball out of its holder. You should also do this occasionally and clean the opening.

After the screws are loosened, the housing can be easily removed. The space for the blue ball is made of its own piece of plastic. The circuit board is held in place with a few screws.

Lift the gray latch and pull the flat cable out of the connector. The trackball holder can then be placed to the side.

Where I would been able to buy the microswitch?
I soldered it out from an old mouse... but I think you will also get it on ebay
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.
