Saw a project a few years ago in an American WW mag about making a dust
extraction system using a proprietary switch unit which switched on the
extractor when the dust making tool was turned on- like the better portable
extractor units. Where can I get one of these switch units- the article had
a supplier and ref no but of course cannot find the article or any trace of
a supplier on the www. Any ideas? (am in the UK but expect can get if it is
a US unit)

Sears has them for $19.95. I saw them in the store, but I'll bet you
can find them online. I have one, works great.

They're expensive, they're a pain to wire up and US units won't work in
the UK. Many of them will also break if you run a cabinet saw's motor
through them - check the rating and that it's designed for woodworking
use, not just computers.

A simple and cheap fix is to use a remote controlled (radio) socket.
I've had these for as little as =A315 for three sockets. Remote control
isn't quite so convenient as automatic control, but it's a lot better
than manual control at the DC.

I use a Sears remote awitch with a relay box as described below.
