Introduction
My MX Vertical developed a phantom double-click on the left mouse button after about a year of use. Out of warranty and out of patience, I tore it apart to see if I could replace the switches. To my surprise, the mouse was a relative dream to take apart and service!
The mouse shipped with OMRON D2FC-F-7N(10M) switches installed. You can find direct replacements for these on many online retailers, but I opted to replace them with OMRON D2FC-F-K(50M) switches instead. You can probably choose a different type of switch if you want (one reader installed Kailh GM 4.0 Micro Switches(60M)), as long as it shares the D2F’s form factor. That’s an exercise left to the reader!
This guide does require soldering, but thankfully it’s all through-hole on some relatively large parts. The hardest part of the job is holding the board steady while soldering the switches’ first contact.
