Timer fan - isolation switch query

[jimma]

Good afternoon

http://www.diydoctor.org.uk/projects/timed_fan_unit.htm

Using the above as a basic template, what I am trying to do is wire my timer fan up in the bathroom and to run off the light.

I do not wish to rip holes in the plaster for a wall switch so a pull cord seems like the best option. I understand that I need an isolator switch as it's a bathroom appliance.

However, it appears that I need a three way pull cord because I have n, perm l and switch l all running to the fan.

My problem? I cannot find for love nor money a three way pull cord isolation switch.

Please help!

James.

I was just about to say "how do you know a pullswitch isolator is off?" then I saw that version has a wee flag that says "off" on it!!! How very clever!
