GPW series micro switch

Overview

Because I recently failed to modify the GPW board for hot-swapping and it broke, I checked Taobao and found that a single board and FPC interface were selling for 9 RMB without shipping. In a fit of anger, I designed my own version.
Currently, the positioning holes in rev1.0 are inaccurate; I will fix them in rev1.1 so that the holes for other micro-motion encoders are aligned!

The iterative version has been updated at another link
