Membrane keyboards are versatile and robust input devices that stand out for their electrical and mechanical properties. They offer high conductivity and pressure sensitivity, combined with a long service life and flexibility. Made from durable materials such as polycarbonate or polyester, they are resistant to moisture, dust and chemicals, making them ideal for numerous industrial and medical applications.

Technology and equipment options

Our membrane keyboards combine the latest technology with the highest level of functionality, individually adapted to your needs. Whether metal snap-on disks for precise feedback, embossed keys for better haptics or LED and LGF lighting - we offer flexible solutions.

Design option

The key and surface finishing of membrane keyboards offers numerous possibilities to optimize the functionality and aesthetics of these input devices. For example, the decorative foil can be replaced with a silicone surface or high-quality, three-dimensional keys can be created by applying epoxy resin.

Structure of a membrane keyboard

The structure consists of base films: Decorative film, holding film, switching film, spacer film and adhesive film (carrier layer). Each of these elements plays a crucial role in the structure and functionality of the membrane keyboard.

Decorative film

The decorative film forms the top layer of the keyboard and is printed on the back to ensure the best possible protection against abrasion. The foil can optionally be embossed for optimal user guidance. Instead of a polyester film, a silicone mat or another material is often used.

holding foil
For fixing snap domes
switch foil
The functional elements of a membrane keyboard are the upper switching foil with the contact surfaces and the lower switching foil with the conductor tracks, switching points and the connection lug. Metal snap-on discs or a direct print of the contact surfaces on the decorative foil can replace the upper switching foil. It is also possible to do without the upper switching foil completely. Instead of polyester, the material polyimide (Kapton) is also recommended. In capacitive membrane keyboards, the conductive layer with the capacitive sensors is located here.
spacer film
The insulating foil separates the upper and lower switch foil. Corresponding recesses are provided on the contact surfaces. In the versions with metal snap disks, the spacer foil serves as a spacer and gives the metal snap disk the necessary space for actuation.
