Conventional switches require mounting holes in the user interface. Not so with the new SCHURTER CHS.
CHS stands forCapacitive Hidden Switch and can be mounted hidden behind the surface of non-conductive materials, making it invisible.
This approach opens up completely new possibilities in the design of user interfaces with specific requirements.
In capacitive switches an electric field is created on the surface of the sensor. With the SCHURTER CHS, this technology has been used to design a switch that no longer requires direct contact of the sensor with the finger to be activated.
Thechange in the electric field (necessary to trigger the switching process) is also achieved if a non-conductive material (glass, plastic, wood or similar) is inserted between the sensor and the finger.
Use in highly sensitive environments
The new CHS can be simply glued behind a wide variety of non-conductive materials, enabling the construction of control elements for devices where hygiene plays an important role (medical and food industry).
The lack of holes, slots and moving parts makes it possible for microbes to settle on the user interface.
This also means that you can choose materials that are particularly easy to clean.
Adjustable sensitivity
The SCHURTER CHS is programmed in such a way that it does not trip in case of field changes caused by liquids or small cleaning contacts.
Activation only takes place with a precise contact on the switching surface.
However, at the customer's request, adjustments can be made, especially to the thickness of the material behind which the switch is bonded.
As standard, the sensitivity is designed for a glass thickness of up to 2 mm.
Design
Switches are always a challenge for industrial designers: their installation in an interface often 'disrupts' its appearance and structure.
The presence of an invisible switch therefore allows complete freedom in design.
Available in 3 variants
The new SCHURTER CHS is available in three different variants:
- CHS 1: design without illumination and with a mounting depth of less than 6 mm. The optimal solution for small developments.
- CHS 2: solution with optical feedback. RGB lighting can be used as a design element.
- CHS 3: version with lighting for use in harsh and demanding environments.
