Top ten off switches

#6 - Wall-socket switch
You use this very special switch every day of your life, and you've probably forgotten all about it, so let's take a moment to remember our old friend the wall-socket switch. But this little fella is an unusual one: most of the world's mains sockets don't have a switch on them at all! Shocking, isn't it?

Anyway, the trusty wall switch keeps us safe from equipment overloads at inopportune moments and for that reason, they deserve our respect and adoration.
