Hello

Total diy noob here... Thanks for taking the time to read this!

My bathroom fan won't turn off for ages, it's a humidity detector. There's also a window to outside in the room which does a better job than the fan anyway!

There's this switch in the hallway but I don't know how to use it. It looks like it needs a certain key but I don't know what it's called. Anyone know if there is a key I can buy to switch it off?

Yes it is known as a keyswitch, so you do need a key to switch on/off.
You will need the manufacturers info to get a replacement key.
But another solution, would be to remove the fuse from the fuse holder just to the left of the switch.

Aha. I thought it was a generic thing. Thanks for your reply.
