Top ten off switches

#8 - Tube emergency stop
Although it's a bit of a cheat for us to call this an off switch, we're going to throw caution to the wind on this one and cover it nonetheless. Our reason for loving this switch is simple: it's a thing of great beauty. Even though in its life it will probably be activated only a couple of times it offers everything we love in a good switch -- although technically it's a lever.

The only real problem with this off switch is that we'll almost certainly never get to use it. It is, after all, for emergencies only. That said, it's possible to buy these online, so perhaps we'll wire some up and use them as light switches.
