I have a fairly powerful extractor fan fitted in my bathroom ceiling
however it has no overrun timer facility so that when I switch the light

how I can add a suitable timer to it..... really need it to run for an
extra 20 minutes or so. Have looked on Google but no success yet.

It's one of those things that is easy to make if you have some electronics
experience. Maplin do a kit which could be adapted to this use. However,
at the end of the day it would probably be cheaper/easier to just replace
the fan with one which has the timer built in.
