Just a design from Ross McBride, this silicone switch design simplifies the light switch concept for people who don't quite grok the "up equals on, down equals off" concept. In this case, one silicone bump means, er, on? And two silicone bumps mean, obviously, off. We think. In any case, you can smash the light with your fist like a barbarian instead of flicking it up or down, like a hoity-toity college professor.
