CNC Probe Homemade DIY Upcycled with Wiring Diagram

I found it somewhat difficult to find a incredibly simple wiring diagram to produce a simple probe for a CNC machine. I used some two wire smaller speaker wire, a wire disconnect, cut two pairs of male and female RCA ends off old RCA cables, a spare charging clip, and a piece of scrap metal that’s very uniform in thickness.

Clip goes on the router/spindle endmill bit, plate goes under. Probe can be removed by unhooking the RCA clips (strip the inside and outside wires). Entire length of the probe can be unhooked just outside my electronics box, so that it can be serviced without unhooking the them from the endstop pins on the control board.

COM/Signal wire goes to the plate
Zmin/-/ground wire goes to the clip

Here’s the basic wiring diagram and result.
