Microsoft Wheel Mouse Optical button switch replacement
The left button switch on my Microsoft Wheel Mouse Optical started failing. The button did not turn on and off at the point where it clicked; more pressure was needed. This led to failed clicks and unintended double clicks.
The fix was simple. While I didn't have the exact same switch, a larger switch used in many other mice fit perfectly. All I had to do was remove an extra (normally closed) pin from the switch. Before closing the mouse, I also lubricated the wheel to improve the feel and reduce noise.
