Hi John > http://gnipsel.com/images/touch-probe/touch-probe-01.jpg > http://gnipsel.com/images/touch-probe/touch-probe-02.jpg
Thanks for the images. That's surprisingly simple. I would have expected that much higher surface quality on the contacts is needed. Interesting. My guess would be be a hard gold on nickle plating on a brass body, elector polishing the surfaces prior to coating might be a good idea. And to ensure a long life the max. current has to be small, but not to small, 500µA maybe and only very small capacitive and inductive loads on the line. I once thought about building a high precision touch probe, but in the end I just used a precision witch from Baumer, <1µm repeatability for about 100 EUR, but that is single contact (1D switch).
