Membrane keyboards – versatile and robust input devices
membrane keyboards are reliable and durable input devices, which impress with both their electrical and mechanical properties. They offer precise conductivity and pressure sensitivity, combined with high flexibility. In addition, they are characterized by their long service life, even with intensive use or under demanding conditions.
Thanks to the use of durable materials such as Polycarbonate or Polyester make membrane keyboards particularly resistant to moisture, dust and chemicals. This makes them ideal for applications in Industrial and the Medical TechnologyWhether in harsh environments or in sensitive areas – membrane keyboards guarantee reliable performance while meeting the highest standards of quality and robustness.
Technology and equipment
State-of-the-art technology and maximum functionality – individually adapted
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.
Design
Key and surface finishing for membrane keyboards
The finishing of membrane keyboards offers many possibilities to improve both the functionality and design of this input devices to improve. Various processes can be used to create individual solutions that are perfectly tailored to your requirements.
For example, the Decorative film through a robust silicone layer to increase durability. For an attractive appearance and improved feel, high-quality, three-dimensional keys can be improved by applying epoxy resin be designed.
Structure of a membrane keyboard
The construction of one membrane keyboard consists of several films that together ensure its functionality and durability. The most important components include the Decorative film, holding foil, switch foil, spacer foil as well as the adhesive film (carrier layer)Each of these layers plays a crucial role in ensuring optimal functioning of the membrane keyboard sure.
Decorative film
The Decorative film is the top layer of the membrane keyboard and plays a crucial role in functionality and durability. To ensure high abrasion resistance, it is printed on the back. This means that the label remains permanently legible, even with intensive use.
For even better user guidance, the surface can be embossed so that the keys are tactilely highlighted. In addition to classic polyester films Alternative materials such as silicone mats which provide additional robustness and a pleasant feel.
holding foil
The holding foil fixes the metal domes 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.
switch foil
The switch foil forms the heart of the membrane keyboard and is responsible for signal transmission. While the upper switching foil which contains contact surfaces are on the lower switching foil the conductor tracks, switching points and the connection lug are integrated.
In some applications, the contact surfaces can also be printed directly onto the decorative foil. This eliminates the need for the upper switching foil, resulting in an even more compact design. For special requirements, for example in environments with high temperatures or special electrical properties, the use of polyimide (Kapton)which offers increased durability and flexibility.
spacer film
The spacer film separates the upper and lower switching foils and thus ensures reliable electrical insulation. Targeted Recesses which enable a precise connection.
For variants with metal domes The spacer foil also acts as a spacer. It ensures that the snap-on disks have enough space for operation, so that the keyboard responds quickly and works precisely.
