From memory I don't think there is a physical switch but its a small mercury switch within the bulb housing that switches it on/off.

Simple bit of engineering!

This, and the contacts fur up... it's a beautiful bit of engineering, like the fact the door windows work with the doors open. :wink:

You don't get that kind of simple genius on a modern one!

Mercury?!!

You sure? I have my doubts about even Porsche using this lethal substance in car manufacturing! That means that every 944 in an accident or scrapped is a toxic health hazard? Where's Clarkson??

Also used for the boot light in Jaguar 420s and presumably S-types. Rarely worked for long.
