Conventional switches inevitably require mounting holes in the user interface. Not so with the new SCHURTER CHS. CHS stands for "Capacitive Hidden Switch". They can be mounted hidden behind the surface of non-conductive materials and are therefore invisible. This approach allows completely new possibilities for designing user interfaces that ideally meet the requirements of specific applications.
With capacitive switches, an electric field is built up on the user surface of the sensor. This technology is used to design a switch with the SCHURTER CHS that no longer requires direct sensor contact with the finger to trigger. The electrical field change required to trigger the switching process is still achieved even if a non-conductive material (glass, plastic, wood, or similar) is inserted between the sensor and the finger.
