Soldering quality looks fine it's a pretty straightforward pcb.

These mechanical switches worked out great with my controller. You can use the green and black wires as normally to read the status of the end stop, or you can supply power to the red wire and have a LED light that comes on when the end stop is activated. I'm building another 3D printer and the forum recommended using this end stop switches. They are very good and add a LED feature that helps when trouble shooting. It seems to be a well-established design and many CNC and 3D printers already have the profile to set them in.
