If it's like reading Greek you might not want to be messing with mains power in a damp environment.

That said, I think with that board you'd want a momentary switch on your pull cord, probably available from some industrial source.

Its not a bad thing to have the fan run with the lights. Long-term, running a shower without the fan is bad from a mold standpoint.

You just don't like the noise?

Suggestion 1. Check behind the switch. There may be enough wires already in there (to control fan and light independently) and all you need is the proper double switch and some revised wiring.

Suggestion 2. Disconnect the light, let the switch run ONLY the fan - then install a light with a motion sensor, that plugs into the wall.

Suggestion 3. Ask the landlord to do it.

I wire up fan/light to same switch in every rental to force tenants to use the fan when showering.

Why not just splice a ceiling fan pull switch into the hot line on a cheap extension cord, and plug it into the socket in the light? Then the fan goes off when the light is switched off no matter what.

Or is the socket in the light always hot? They're not usually wired that way.

I suspect you have not lived in places where humidity has been consistently that low. I can post links showing the importance of raising humidity to at least 20%, for human health. Not to mention for the benefit of all the shrinking of panels and trim right now. FWIW I've been here ~8years, and the place looks exactly like when I moved in. I do take care of stuff. Understand I can run the shower infinite time periods at max hot and not fog a mirror 1-1.2m from that shower- even a little. I think at this point, since I will very seldom use it- this is more for guests, I will install a ceiling fan service switch (as in post photo above) in it and remember to check it gets turned off.

We do have to run humidifiers all winter, as it gets super dry here. I have breathing problems without it.

Whatever you do, make sure you undo it when you move out.

Motion sensing light switch? We put one in our bathroom so that the kids could use the bathroom without us having to go turn on the lights every time. The light turns off after 5 minutes of no movement - sounds like what you're looking for.

You can buy timer switches. The kind like public bathrooms have with the sensor eye on it.

I would consider wiring up one of those tucked up in the box (so the sensor eye doesn't see any movement) and then hook a pull chain to a bellcrank that pushes the button when you pull the cord. The Bellcrank could be one of those hinge-pin-mount doorstoppers. Ajdustable and cheap.

Like this:

That actuates one of these:

Can't you just buy a humidity sensing fan or fan control.

Let automation take care of your issue.

I was hoping to see something about an automatic E36 M3 smell sensing bathroom vent fan. Still aways in the future I suppose.

The Panasonic I installed when I renovated the master bath a few years ago has a motion switch, humidistat and timer. I rewired the night light to the motion switch/timer and set it long enough for a night time pee and exodus without a mid-micturation hand wave to re-illuminate.
