I have a bathroom extractor fan that is activated when the bathroom
light is turned on and eventually times out when the light is turned
off. This is a rubbish solution in my opinion since:

(1)To get the fan to run when showering, the light needs to be turned on
even when it is daylight.

(2)When I want to turn the light on to use the bathroom but not have a
shower, the fan turns on. This is especially annoying when you have just
got your 2 year old son too sleep who then wakes up because of the noise
of the fan.

(3) There is no way of quickly turning off the fan before a fully
fledged (2) develops.

The best solution to me seems to remove the fan from the light switch
and give it, it's own separate pull cord switch with a neon indicator so
that you can tell if the fan is actually on or in time out.

Any reasons why I can't do this or is it just a bad idea?


Perfectly good plan.

You can choose either an on/off swtch or you could use a momentary
switch, the latter will start the fan for the 20 minutes or whatever
when pressed, and won't keep it running indeifinitely. You could also,
if you prefer, get a momentary switch that will fit a half inch hole
drilled in the fan casing.

I'd also consider unscrewing the fan and remounting it using added cut
down rubber tap washers plus metal washers on each side of the fan
case. I always fit them this way, and for an extra minute's work you
get a much quieter fan in most cases.
Ie wall - rubber washer - fan case - rubber washer - metal washer -
screw head.
When using this method, just tighten the mounting screws till there's
no slack, dont go too tight or the noise reducing effect will be
greatly reduced.
