wiring probe with led

[Morfeus80]

Dear all,

I have built a touch probe and I would like to add a led to have also a visual output when it's active. The led should be ON when it's connected and switch OFF when it touches and opens the circuit.
My break board is a UCBB, but I have not clear how to do the wiring including the led.

Thanks.

assuming it's wired to work the same way as typical probe, simply connect to probe input on the board, your other wire from probe will clip or magnetically attach to spindle, then apply the proper +V to the 3rd wire on the probe to drive the LED. it will never be on until the spindle touches the probe
