Capacitive Touch Technology

Capacitive touch buttons are widely used in modern electronic products due to their long lifespan, sealed structure, and flexible design possibilities. From consumer electronics to industrial control systems, capacitive touch technology has gradually replaced traditional mechanical buttons in many applications.   With over 25 years of manufacturing expertise since 2000, we have witnessed the evolution of touch technology from simple tactile switches to the highly sensitive capacitive systems used today. This article integrates our front-line production data and R&D insights to provide a comprehensive engineering perspective. The content is based on practical design experience and real-world applications, making it especially useful for engineers, product developers, and B2B buyers...

Application Note Abstract   This application note considers the possibility of using springs as sensors. A comparison with solid conductive sensors and recommendations for the practical usage of springs are also discussed.   Introduction   CapSense™ may be used in several applications. However, some applications cannot install printed circuit boards with a set of sensors directly under the overlay or attached to the device case. Examples of such applications are “white goods” (that is, cooktop, washing machines, refrigerators, microwave ovens, and others) and various vehicle electronics, such as radio sets, TV tuners, dash boards, seat occupant detection, and so on.   Metallic spring sensors may be used as an alternative to solid conductive sensors.
