SWMBO wants the shower room fan to come on by means of a pull switch, but to go off again after a set time (maybe 15 mins) if you forget to do it manually after showering. Then, the next person comes along and wishes to switch on the fan does so as normal (in other words the switch has reverted to off automatically).
If my description males any sense,, is it possible?!
