Tool height sensor.

Hello

Just a quick question or two about tool length sensor issues.

I have the plate and crocodile clip sort which was working well then stopped working. UCCNC says something like the probe is active. I have had some advice saying its an earth/ interferance issue.
Not had time to sort it out but wondering if I used a switch type it might solve the problem.

I have seen this type https://www.sorotec.de/shop/Tool-Len...Small-8mm.html

and these other ones

Do these work on an actual switch rather than conduction through the probe, if so is this likely to avoid the problems of interference I am having by being a more positive on off, if you see what I mean.

£20 is worth it for not having to trouble shoot it.
