I would like switches for extractor fan / possibly electric shower /
lights in the bathroom.
I don't want strings (too many) or switches outside (kids etc can
switch them off when you're in there - its great fun !).
Best solution - air switches or low volatage switches and relays ?
Which is the best / most likely choice ?
Or, I suppose a DIY mechanically isolated contraption. (Like a rope
around a bicycle wheel or something).
Any ideas ?

How many is too many? I can see you will only need two in you bathroom with
a fan isolator outside the room.

Our extractor fan switches itself on and off automatically, it's controlled
by an humidistat. We're delighted with it!

We leave the shower unit switched on all the time, the shower itself is then
operated by the button on the unit.

I wonder if something like the switch for some lavatory flush systems can be
bought - the ones where you simply pass a hand over it without contact. Is
that an air switch?

I beleive that provided the IP rating is adequate you can use
non-pull-cord types. A suitable one would be an outside MK membrane type.

If they are far enough away from a bath or shower then you can use
ordinary switches. Whether people want to do this with a light
switch that is frequently operated, in a room that will often be
damp, is up to the designer. I wouldn't.

As others have said, the fan and shower don't really need switches
that are operated regularly.

You neglect to mention the size of the bathroom. However you can have
ordinary switches if you prefer as long as you can place them in Zone 3
(or outside the zones althgether if it is a big room). Same applies to
the fan isolator. Note that it should not really be placed outside the
room with the fan unless it is a type that can be locked off.

If you are concerned about high levels of condensation on the switches
then choose one witn a suitably high IP rating.

We were looking at a house the other day, with
a retrofitted en-suite shower. The neon on the
pull switch was not lit, and it had been mounted
on such a high ceiling that the mechanical ON/OFF
indicator was difficult to see.

For this sort of reason I dislike (distrust?)
these pull-pull switches, so had a mild search
for wall-mounted alternatives. There are a number
of heavyweight wall-mounted rotary switches, meant
for industrial use in wet areas. They provide a
nice easy_to_see indication of ON/OFF.

Are such switches defined as acceptable in wet
areas in the domestic situation?
