How does a touch sensitive lamp works?

From many years switches that must be pushed or flipped to break and make mechanical connects are not choose over switches that are sensitive to human touch. The main advantage of these touch sensitive lamp or switch is that they do not get gummed by or damaged by touch that brings moisture and dirt to the switch. Over a period of time different human body property have been used to flip touch sensitive lamps.

Resistance

Human body conducts electricity well as it is mostly made up of water. Fingers can form a good circuit by placing the two (button / lamp and finger) contacts together closely by touching it.

Temperature sensor

Compared to surrounding air human body I warmer. Many places use this temperature difference to work their functions such as elevator or lamps.  The lamps on patios also sense the neat of human body and function in similar manner.

Radio receptivity

Human body can receive good radio waves. This can be understood by the instances that when you touch an antenna its reception on TV or radio gets better. Some touch sensitive lamp, use of radioactive wave reception technique to make changes.

Capacitance, it is the fourth property which is used by the touch sensitive lamps. Capacitance is similar to capacity. It can be said in simple terms as ability of anybody to hold electrons. Certain capacitance is present in the lamp when placed on the table. When these touched by you, a circuit is created to charge the lamp with electrons. It will need certain amount of electrons to fill it. Your body adds to the capacitance of the lamp. The circuits detects the difference of electrons between human body and the lamp. This leads to it function of switching on and off. Now with recent you can even convert your normal lamp to touch sensitive lamp by just adding a plug- in box. This work on the same principle as well. Three level brightness setting is provided mostly by many touch sensitive lamps even while not using three-way bulbs.
