Our membrane keyboards combine innovative technology with maximum functionality and are individually tailored to your requirements. Whether you metal domes for precise tactile feedback, embossed keys for improved haptics or a LED and LGF lighting for optimal visibility – we develop flexible and tailor-made solutions that fit your needs exactly.
Key and surface finishing for membrane keyboards
The finishing of membrane keyboards offers many possibilities to improve both the functionality and the design of these input devices. Various processes allow the implementation of individual solutions that are precisely tailored to your requirements.
The decorative film can be replaced with a robust silicone layer to increase resistance. High-quality, three-dimensional keys can be designed by applying epoxy resin. This ensures an attractive appearance and improved feel.
Structure of a membrane keyboard
The structure of a membrane keyboard consists of several films that together ensure its functionality and durability. The most important components include the decorative film, holding film, switching film, spacer film and the adhesive film (carrier layer). Each of these layers plays a crucial role in ensuring that the membrane keyboard functions optimally.
Decorative film
The Decorative film forms the top layer of the membrane keyboard and is crucial for functionality and durability. It is printed on the back to ensure high abrasion resistance. This means that the label remains permanently legible, even with intensive use.
The surface can be embossed for better operation. This makes the buttons stand out tactilely. In addition to classic polyester films, alternative materials such as silicone mats can also be used. These offer additional robustness and a pleasant feel.
holding foil
The holding foil fixes the metal snap-on disks and ensures that they stay securely in place. This ensures that the keyboard functions reliably and prevents unwanted movement of the switching elements. This means that operation remains precise and durable, even with frequent use.
Switching foil: The heart of the membrane keyboard
The switching foil is central to the function of a membrane keyboard and is responsible for signal transmission. It typically consists of two layers:
- Upper switching foil: This contains the contact surfaces.
- Lower switching foil: The conductor tracks, switching points and the connection lug are integrated here.
In certain applications, the contact surfaces are printed directly onto the decorative film. This eliminates the need for the upper switching film, which enables a more compact design.
choice of materials for special requirements
For applications with special requirements, such as high temperatures or specific electrical properties, the use of polyimide (Kapton) is suitable. This material offers increased resistance and flexibility, making it ideal for demanding environments.
spacer film
The spacer foil separates the upper from the lower switching foil. This ensures reliable electrical insulation. There are targeted recesses at the contact points. These enable a precise connection.
In versions with metal snap-on disks, the spacer foil also acts as a spacer. It ensures that the snap-on disks have enough space for actuation so that the keyboard works quickly and precisely.
