Capacitive Touch Sensors


Capacitive switches, also known as capacitive sensors or capacitive keys, are the interface option of choice for a variety of appliance, medical and industrial applications that don’t require the functionality of a full touch panel but require an elegant, dependable and sealable solution. Depending on the application requirements, capacitive switches can be backlit or integrated into a display assembly for a cost effective but sleek and extremely modern design.


A capacitive touch switch works by using body capacitance, a property of the human body that gives it great electrical characteristics. As the user’s finger gets closer to the switch’s surface, the switch’s electronics detect a change in the capacitance of the surface and registers a touch. Capacitive switches can also integrate sliders or wheels for additional control functionality.


Because there are no mechanical components or moving parts, and the sensors can be placed and sealed underneath a rigid material (such as glass, PET or ABS), capacitive touch controls have excellent reliability and life spans.  With the additional benefit of zero force actuation, capacitive switches enhance the user experience of any product.


Wide-Ranging Design & UI Flexibility


The exceptionally simple, flexible and modular design of capacitive switches offer a number of key benefits:-


•     Long lifespan - up to millions of touches, No moving parts to breakdown or fail

•     Easy integration - plug and play HMI assemblies

•     Design Flexibility - Flexible substrate allows for greater design choice, different panel geometries and thinner stack-ups

•     Quicker Development & Lead Times - Modular design allows for faster and easier development; printing technology allows for 8-10 day turnarounds

•     Finishing – Variety of materials and display solutions allows for easy price and design differentiation
