Read my lips... THERE IS NO SWITCH.
I've had this lamp for years. There is no switch, anywhere on the lamp. To turn the thing on, you... touch it.
Touch the lamp anywhere along its structure - the base, the shade, the shaft, even the bulb receptacles - and it comes on. But it only comes on when something living touches it; a finger, a hand, a tongue, or my dog will turn it on, but a book, or a pen, or a shirt, or my keys yield no reaction. As near as I can tell, it has to be touched by something living to activate.
Like I said, I've never really given it much consideration, and I've had the lamp for years. But here I am, bored out of my skull, playing around at PhotoShop, wasting time, and now I've started to wonder about it.
So how in the devil does this thing work?
