om...
I have worked out the wiring (which is how I first proved that the
humidistat was on most of the time) but I would like to fit a small LED
which only lights when current is passing through the switch.


Did you get your answer yet, David W.E.?

I read most of the thread but couldn't see any simple answer...

Main answer I got was that I asked the wrong question.

The lights in switches are apparently neons not LEDs.
