I went to swap a fan for a customer, they wanted a humidistat one. When I dropped the old fan I found it was wired with T&E.
I explained there was no permanent live so no overrun was possible, and that I'd either have to make a lot of mess running a three-core or they'd be best off leaving the light on after using the shower, they said to put it back for now.
Then I thought, could the switch act as the overrun timer leaving the live live after switching off for a period of time? I've looked on live and can only see the push button on for a certain time switches, for hallway lights etc.
You'd probably want two switches, one to isolate the supply to the the timer switch and hence the light (and FIS), the other to be the timer switch.
Does anyone know is a switch like that exists?
