Touch lamp
You can turn almost any lamp into a touch lamp. All you
need is a lamp with a metal base or pole and a touch lamp control switch.
You can actually turn any regular lamp into a touch lamp, meaning that
you can turn any lamp on and off by touching any part of the touch lamp.
When you have a touch lamp, you no longer need to worry about fumbling
in the dark for the tiny switch or knob to turn on the light: you merely
need to touch the lamp. Of course, the amazing thing is that it is your
human touch that turns on a touch lamp. In other words, if your cat
or dog or a book, etc. touches the lamp, it will not turn on. It only
turns on because of capacitance which is the ability of your body to
store electrical charge.
