What is it:
Everything thats great about the Klicky probe now in an awesome PCB package for even more precision. includes assembled pcb's. Printed parts required for final use.

From the designer:
this design attempts to replicate Klicky as closely as possible using a PCB-based design, to try and achieve the following aims:

1. Reduce the problem of magnets working lose or seating poorly in printed parts
2. Increase the current being switched, which might possibly result in a longer switch lifetime.
3. Add LED for easy visual debugging
