I'm replacing the ceiling in my bathroom, and decided at the same time it might be nice to install a dimming pull-cord light switch (Screwfix sell one).
The only thing is that the extractor fan is fed from the lighting circuit (through an isolating switch next to the fan which I plan on replacing as it's poorly mounted and has seen better days - just generally scruffy).
The fan is the timed type that runs on for a few minutes after the light goes off.
I don't want to "dim" the supply to the extractor fan, so I'm thinking my only options are probably to:
-leave the circuit as-is with no dimmer
-install a separate pull-cord circuit for the fan,
-or possibly (and I don't know if this is feasible) install a relay on the lighting circuit to control the feed to the fan.
With regards the third option, is this feasible (and legal!) in a bathroom installation? I don't like the idea of two separate pull-cord switches, so it's either option 1 or 3 for me I think.
Many thanks!
