I have an extractor fan in the bathroom.

It is controlled both by a humidistat (separate, not built in) and also
by a ceiling pull switch for manual operation. Supply splits to feed
both of these, then runs to the fan where they terminate at the same
point. Problem is if the fan is on I don't know if it has been turned on
and left on or if the humidistat has switched on. So an indicator would
be useful.


Isolating relay?
Switch indicator relay coil output fan
humidistat fan

Sorry it's not very elegant solution, shame they didn't put an led on the
stat.

That's all rather more effort than I want to go to. - yes it is a shame
there isn't a led on the stat.

Or 40A pull switch with an on/off mechanical indicator in the base? Quite
rare.
A plate switch outside the door?

The ceiling switch is a possibility, though not one I really want to go
with. The landing is nicely new plastered, I don't want to disturb that.

TBH, I'm looking for a cheap and fairly easy job, otherwise I'll just
leave it alone.
