Intelligence Touch Switches

 Home / Intelligence Touch Switches
A touch switch is a type of switch that only has to be touched by an object to operate.

A touch switch is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.

There are three types of switches called touch switches:
A capacitance switch needs only one electrode to function. The electrode can be placed behind a non-conductive panel such as wood, glass, or plastic. The switch works using body capacitance, a property of the human body that gives it great electrical characteristics. The lamp keeps charging and discharging its metal exterior to detect changes in capacitance. When a person touches it, it increases the capacitance and triggers the switch.

All the circuits and projects we describe in these articles consist of very important "building blocks" that you can add to other designs. This time we describe the concept of touching a plate (or two plates separated by a small gap) and turning a circuit ON or OFF. A TOUCH PLATE is classified as a high impedance device (or high impedance circuit) as the effect of a finger will be detected by the circuit connected to the plate.

If only a single plate is present, the circuit will actually be picking up "mains hum" from the finger. If the plate has a signal on it (from an oscillator), the effect of your finger will be to remove the signal (or reduce its amplitude considerably) and a detecting circuit will be activated.


  • Touch Switch Working

  • A touch switch for an electrical appliance having a capacitive flat electrode, a light source, a transparent cover and a printed circuit board connected to the electrode is disclosed.
  • Mounting of Light Source

  • The light source is mounted on a face of the printed circuit board opposite the transparent cover presents a cut-out for allowing light transmission from the light source.
  • Lighting Controls

  • Adding lighting controls in your home, from simple wall switch dimmers to programmable control systems add adjustable voltage to your light fixtures, will provide multiple benefits.

Key Points About Intelligence Touch Switches:

  1. Flexibility for the use of lighting in each room
  2. Save energy because of reduced wattage
  3. Controls add flexibility to the use of lighting in each room.
  4. Having the capability to lower lighting levels in any room allows you to save energy and money.
  5. You can use them to create multiple lighting presets for one room.
  6. You can use one-touch recall to switch back to the prior level of light, and some touch dimmers use a lighted indicator to show the current setting.
  7. Many also have push-button control that allows you to turn off the light and retain the current setting.
  8. Adding lighting controls in your home, from simple wall switch dimmers to programmable control systems add adjustable voltage to your light fixtures, will provide multiple benefits.

Features of Intelligence Touch Switches

  1. Intelligence Touch Switches are always the best option to save your money.
  2. It comes very small in size, so that easy to handle.
  3. Its light weight, means easy o perform any operation.
  4. Household appliances are widely used terms.
  5. It can avoid the long-term power-consuming electrical power.
  6. The touch security is cheap in cost and hence can be used for house security at doors.
  7. It is useful circuit for dusty conditions.
  8. It is very useful in rainy conditions
