Structure of a membrane keyboard

The structure of a membrane keyboard consists of: five basic parts: Decorative film, upper and lower switching film, spacer film and adhesive film. Each of these elements plays a crucial role in the structure and functionality of the membrane keyboard.
Removing a membrane keyboard

Decorative film

The decorative film in focus
As the outermost layer, the decorative film of the membrane keyboard not only offers protection against abrasion, but also an attractive design. Usability is optimized by printing from the back and the optional embossing. Epoxy, silicone or illuminated keys can also be used in the key design.

switch foil

Key element switching foil
The switching membranes, which consist of an upper and a lower layer, are the heart of every membrane keyboard. They contain conductor tracks, switching points and LEDs and thus ensure the necessary interaction. Metal snap disks or direct printing on the contact surfaces can serve as innovative alternatives. Instead of polyester, the material polyimide, also known as Kapton, is also recommended.

spacer film

Distance film keeps distance
The distance foil, also known as a spacer, isolates the upper switching foil from the lower switching foil. Thanks to precise recesses at the contact points, it enables precise functionality and supports the necessary actuation mechanism in models with metal snap disks.

More slides

Depending on the function and features of the keyboard, additional slides can be added.
The example shows a membrane keyboard that consists of a membrane composite of 8 membranes.

Building a membrane keyboard

Tactility and ease of use

The combination of tactile feedback, personalized design and robust protection makes the membrane keyboard the first choice for a wide range of applications, from medical technology to industrial automation.

Metal snap disks for noticeable feedback

Concise tactility and high actuation forces

Metal snap disks for membrane keyboards
For a distinctive tactile sensation and a powerful actuation are used in membrane keyboards metal domes used. When you press a key, the disc lowers and thus creates contact with the conductor track. Metal snap disks are available in various sizes and shapes. In particular, illuminated buttons use snap disks with a central cutout for LEDs, which highlights the lighting of each button individually.

The kraftDepending on the model, the amount required to trigger the metal snap disks is between 40g and 750g. This allows the feedback to be precisely adjusted depending on user preference. In addition, these components achieve an impressive Lifespan of up to 10 million cycles, which makes the membrane keyboards particularly durable.

We also offer the integration of Dual touch metal snap discs. These metal snap disks can two different strength levels detect and close two electrical circuits in a single switch. Light pressure makes initial contact, but does not provide any tactile feedback. Applying more pressure engages the dome and closes the second circuit, providing the familiar tactile feedback of traditional metal domes.

As a manufacturer of membrane keyboards, we advise you in detail on the subject of metal snap disks and work with you to find the optimal solution for your input system. We will be happy to provide you with samples upon request.

Key embossing of a membrane keyboard

Improved feel thanks to individual embossing

Key embossing on keyboards

Individual embossing of the keys on a membrane keyboard not only ensures a visually appealing look, but also improves finger guidance and offers noticeable tactile feedback. By specifically embossing the keys, a haptic orientation is created on the surface, which not only enables intuitive operation, but also significantly reduces incorrect entries and thus significantly improves the user experience.

A variety of embossing options for every requirement

When it comes to embossing options, there is a wide range of options available classic cathedral embossing, which enables tactile feedback even without metal snap disks, to special ones Terrace and frame embossing enough for smaller keys. This diversity allows each membrane keyboard to be tailored precisely to the specific needs and desired design of each individual area of ​​application. As a long-standing manufacturer of membrane keyboards, we are able to use high-precision embossing processes and realize individual designs.

Capacitive membrane keyboards

Capacitive membrane keyboards – a class of their own

Capacitive membrane keyboards work with capacitive sensors that detect touch and convert it into electrical signals. A touch changes the electrical capacity at the contact point, which is registered by the sensors and converted into an input signal. This technology enables smooth and intuitive operation without any effort.

Capacitive keyboards offer precise input options such as wheels and sliders and set new standards in user interaction. They are particularly durable because they do not require any mechanical parts and are easy to clean. They are also resistant to dust and moisture, making them ideal for demanding areas of use.

Light Guide Film Technology (LGF)
Membrane keyboards can be effectively illuminated by using Light Guide Film Technology. A thin film is used that absorbs the light from LEDs attached to the side. This light is then evenly distributed across the entire keyboard surface.
Light Guide Film Technology ensures that each key is illuminated clearly and evenly, which is particularly beneficial in low light conditions. This not only improves visibility but also enhances the aesthetics of the keyboard.

RFID/NFC technology

RFID/NFC technology

We offer you the option of optionally equipping your membrane keyboards, capacitive buttons and decorative films with advanced RFID (Radio Frequency Identification) and NFC (Near Field Communication) technology. The integrated chips are located within the film and are therefore optimally protected from environmental influences.
Areas of application for membrane keyboards with RFID technology include, for example, access control systems and user identification systems.

Viewing windows and touch panels

Keyboard & touch panel

The Combination of keyboard and display technologies represents an effective method to optimally utilize the strengths of both systems.

A complementary keypad next to the touch display significantly improves the user interface by providing quick and easy access to frequently used commands or predefined parameters. The haptic feedback of the membrane keyboard significantly reduces user errors and thus increases operating safety. Integrated snap disks provide both tactile feedback and audible click feedback when the buttons are pressed.

Various technologies are available for integrating touch screens:

One method is to punch out the area for the display, while another is to embed a viewing window into the membrane keyboard. The specification of these windows can be customized for gloss, matt finish, anti-reflective coating, scratch resistance, UV resistance and color.

A combination of film and display is achieved using a highly transparent adhesive layer that ensures light transmission of over 99%. This bond creates a uniform surface that is chemical resistant and sealed against liquids and dust. This makes such assemblies ideal for use in food processing, laboratories and the medical sector.
