Inductive Limit Switch problem

[JAZZCNC]

Has anyone else seen this faint glow before and, if so, how did you fix it?

All help gratefully received.

I've seen this before when the voltage is close to the minimum 6v. I've also seen it when wired wrong but can't imagine you've done that. Another thing that often happens is the switch can be marked up wrong ie: NPN when should be PNP or NC when NO.

What voltage and breakout board are you using.?
