That's a Latching reed switch. Normal ones will revert immediately the magnet in moved away. Latching reed switches are becoming harder to find foir some reason?
Has anyone found source of latching reed switches? I've been looking but only found ones that are pretty expensive

The link in Steve's post #23 has them. Fourth up from the bottom. They wont be cheap though as there is little call for them!

At the moment I have fitted little dip switches on the bottom of the chassis but a latching reed switch would be nice, but not too fussed to change from a dip switch

I did a flashing red LED controller using a 8 pin microcontroller on a guards van.
I had a small switch beneath the van to turn it on/off.
LED's cant be driven by voltage but only a current so need a resistor in series with them for long life.
Occasionally you can get away with just a battery but its not normally recommended.
