Aussie, Good on ya mate!. Yeah I found it, What I failed to mention was the fact that these older type switches had thier own boxes. Usually they'd be screwed to a dwang(nogging) on it's edge through the back of the box. If you wanted to change it, you'd have to open the wall around the box, to take the dwang out. You can't get a standard flushbox in there with a dwang in the way. Great to have experience in these sorts of things though.
