Top ten off switches

#5 - The consumer unit
Here it is, the big daddy of them all, well, certainly for domestic instillations. It's also not just one switch either, so if you love switches, you're going to go loopy for one of these. The good news is, you probably already have on in the cupboard under the stairs.

Obviously there's the master power control, which will generally be left on for most of its life. Then there are the secondary power-breaking switches. These replace boring old fuses and help to prevent your house from burning to the ground when someone tips a cup of water over the TV. This particular model is the Wylex NHRS. Oh, and for those with a taste for such things, this bad boy is metal-clad. Yum.
