Firstly, may I apologise for dragging this subject up again when there are some excellent postings already on this site, but.........
I was planning to install a timed shower extractor this week end. I understand the need for the four wire connection (permanent live, switched live, neutral and earth).
I will take the feed from an adjacent ceiling rose for permanent live, neutral and earth and the switched live from the bathroom pull cord light switch.
So far so good. (I hope)
This would then give me a fan that came on with the light, and stayed on for a timed interval.
I then planned to introduce a further three pole pull cord switch into the circuit so that I was not disturbed in the night if the ensuite loo was used.
My local B&Q electrician has never heared of a three pole pull cord.
Questions
a) does my plan above make sense?
b) Would it be ok to wire the scheme without the isolating three pole pull cord and introduce one at a later date if I can find one
or c) would it be ok just to switch the permanent live with a single pole pull cord or is this stacking up safety issues for future maintenance.
many thanks once again
