Logitech M310: Mouse Button Repair

For some time it became more and more difficult to get a click out of the mouse wheel switch of my old Logitech M310 mouse – inconvenient in programs like KiCAD. I also have a newer and “better” M705 mouse, however, using this one seemed to increase fatigue compared with the old M310.

The mouse wheel switch SW3 (center) is one of the cheap through-hole tactile switches used everywhere – and sure enough, I didn’t even have to order a replacement. After a tiny bit of disassembly, desoldering, replacing old switch with a new 10 cent one, soldering and re-assembly it works perfectly again. Certainly cheaper and more fun than buying a new 30 to 40 EUR mouse. Why didn’t I do that sooner?
