Capacitive Switch

Capacitive keypads and switches use individual sensors that form electric fields and act like a capacitor plate. This field penetrates a variety of materials; the most commonly used is glass. When a user touches the field, the capacitance changes and causes a signal to be triggered. In addition to buttons, it is possible to integrate a capacitive touchpad.

In contrast to touch screen systems, where the controls are displayed graphically via monitor, this technology involves delineated, physically present buttons. We develop and manufacture the electronics and apply them to any requirement – from backlit individual switches to customized keypads behind glass.
