Interesting reading. Thanks for the question- I learned too!
Have a great day!!!

Answer 2

They work great by touching them at first then they develop a mind of there own and turn on and off at will. You go to bed it a dark room and wake up a few hours later to the light been on.
Gave up went back to a switch light, much more reliable

Answer 3

These lights sense a change in capacitance. When you touch a metal part of the lamp your body becomes a capacitor and the lamp detects the change in capacitance as an indicator to turn on/off.

Answer 4

By putting your finger there, you add capacity which is sensed by an electronic circuit, which then switches the load to the position it is not in.
Same thing that is used with lots of elevators...
That's why touching it with a pencil for example, does NOT work, since it doesn't change the capacity of the circuit sufficiently.

Answer 5

Generally, you touch the unit anwhere along its metal frame and then the light bulb attached to it is either activated or deactivated depending on the state the bulb is in at the time.

Answer 6

Just a wild guess, but I assume body heat or sensing pressure! You have to touch it, so that is all that I can come up with!

Answer 7

Either a mechanical switch, if the cover moves, or a capacitance switch if it doesn't. The touch of your hand changes the capacitance.

Answer 8

I believe it senses the bioelectricity of your body. Thats why when you touch it with something like an eraser or your shirt it will not turn on or off.

Answer 9

well you have to take the inner molecular structure of the electro- magnetic field combind it with conduction ad get rid of the switch.something like that.i don't really know.i was making it up

Answer 10

u touch it...it lights

Answer 11

There is a light switch
