The capacitance touch switch technology is to coat a conductive layer on one side of a quadrilateral insulating sheet, when a tiny voltage is applied to the conductive layer, a uniform electrostatic field is generated, and when a conductor contacts the surface of the insulating sheet of the capacitance touch switch, a capacitance value changes, so that a sensor can measure the change of the capacitance from four corners of the insulating sheet, thereby knowing the current touch position of the conductor.

Because the operation mode of the capacitive touch switch needs to sense the change of the position of the capacitor by contacting the surface of the capacitive touch switch, the surface of the capacitive touch switch can only be the surface of an insulator such as glass or plastic, and metal or other conductive materials cannot be used as the surface of the capacitive touch switch, so that the traditional capacitive touch switch has low degree of change in appearance design, cannot design the texture presenting metal technological sense, has reached a critical point, is difficult to be pressed down, and belongs to a difficult problem to be overcome by manufacturers.
