Human E&C Co., Ltd., Specializing in manufacturing SWITCH products centered on printing technology
Our touch switches are capacitive. When a part of the body touches the touch area, it alters the capacitance between the body and the touch area.
This change in capacitance at each key's electrode is measured to detect whether a touch input has occurred.
The Cs value in the non-contact state is read, and the Cf (capacitance) generated upon contact is accepted as the contact value to determine if a touch has occurred.
