How does a touch lamp work?

Answer 1

A membrane switch is an electrical switch for turning a circuit off and on. It is used as user-interface for computers. Many people use it without even knowing they do.

Answer 2

you flick it

It works by interrupting and by restoring electric current on a circuit. It may disconnect one or both wires ( phase and neutral poles). Interrupting both wires is safer than only one pole.

Answer 3

A touch switch uses an interesting property of a transistor. The transistor can trigger from a voltage source which has an incredibly low current level. A touch switch injects a signal into the metal of the lamp, but the signal runs through either a high value resistor or a capacitor first. When you touch the switch, the voltage is absorbed by the mass of your body, and since both the voltage and the current level are so low, you can't feel it. The LOSS of signal is detected by the logic circuit, and the switch state is toggled.

Answer 4

A simple switch is just two paperclips. These paper clips have to be closed for the bulb/buzzer to work. If the paperclips are not connected then the circuit will be cut short which means not working.

Answer 5

A "Circuit" is a closed loop, whether it be in horse racing, mail delivery, or the flow of electricity.

Consider an electrical circuit: It requires a closed loop of a conductor in order to flow. If you cut the conductor into two pieces, electricity no longer flows because the circuit loop is no longer closed.

Well, instead of cutting wire when you want to turn your lamp off, for example, a switch is inserted into the electrical circuit to 'open' the circuit and 'close' it, again with no cutting of wires.

Answer 6

The basics is a balanced capacitance bridge. When unbalanced by touching, a switch is turned on and a current will flow. See related links for a complete description.
