Hi All

I am in the UK and have bought a timer type Extractor fan for my Bathroom.
Because it is such a bright room people don't always turn on the light when
they use the Shower.( That is relevant to my question honest!)

I want the Extractor to switch on when any one of the HOT taps or the shower
are operated. ( the shower is not one of those electric ones).

So I was thinking that a Flow switch installed in the piping run could be an
idea to activate the extractor.

Any one know what I need to buy ? My extractor is a Air Master xf4t 240 V AC
and requires a 3 amp fuse - if that is any help.


Thanks
