We realize customer-specific silicone keymats
Benefit from our many years of experience and expertise.
Silicone safety mats have always been one of our core competencies and we support and advise you in detail Equipment and material selection. Also the complete one development and construction We can provide you with a suitable silicone keyboard for your application.
Proven classic
The single, classic silicone keymat is still one of the most common switching elements in the electronics and automotive industries. As the central component, it triggers a direct switching function on the circuit board underneath and determines the haptics, the visual and tactile impression and the electrical behavior via the integrated contact elements. In addition, the safety mat often assumes a sealing function on the printed circuit board.
Application of silicone keymats
Silicone keyboards are often used in devices and instruments where easy and reliable operation is required. They are used, for example, in remote controls, industrial controls and electronic measuring devices. In addition, silicone switch mats enable noiseless operation, which is advantageous in some areas of application such as medical technology or audio engineering.
Module?
In addition to the pure safety mats, we also realize the complete assembly with matching Plastic housing and the connection technology.
Our silicone safety mats are used in almost all industries. Here you can see one small excerpt of our references:

Benefits of Silicone Keypads
Silicone safety mats offer numerous advantages in various areas of application. They are particularly useful in environments where robustness and reliability are required, such as in industrial automation or medical devices. Their waterproof and dustproof nature makes them suitable for use in difficult conditions. In addition, silicone safety mats enable precise control and can be individually designed to meet the specific requirements of each application area. Their ease of cleaning and maintenance, as well as the ability to produce them in different colors and shapes, make them an ideal choice for many technical applications.
-
Flexibility
Silicone keyboards are extremely flexible and can be made into a variety of shapes and designs. In addition, the keyboards adapt perfectly to the housing construction. -
longevity
Silicone safety mats are very durable and resistant to wear, scratches and other damage. They also have no resistance to moisture, dirt, chemicals and thermal influences. Their long mechanical lifespan up to 10 million switching cycles makes it a long-lasting solution with low maintenance risk. -
tactility
Silicone keymats provide excellent tactile feedback. The actuating forces (force-displacement behavior) can be flexibly selected from 20g - 500g, the key travel from 0,3 to 5,0 mm. The buttons can also be made with different heights and contours to provide an enhanced user experience. -
Electrical contacting
Diverse implementation options for electrical contacting - from inexpensive carbon printing to high-quality metal contact pills with a current carrying capacity of up to 2A. The use of metal snap disks or the actuation of a tact switch is also possible. -
Lighting
Selective or homogeneous backlighting of the keyboard or individual keys is possible without any problems. -
Waterproof and dustproof
Silicone is naturally water-repellent and dust-proof. Therefore, silicone keymats offer some protection against moisture and dirt ingress, which increases the longevity and reliability of electronic devices. -
Easy to clean
Thanks to the water-repellent properties, silicone keymats are easy to clean by simply wiping with a damp cloth. This is particularly important in environments where hygiene is an issue. -
Low noise level
Silicone keymats generally produce little noise when the keys are pressed. This can be particularly important in environments where quiet operation is required.
As a central component, a silicone safety mat triggers a direct switching function on the printed circuit board underneath and determines the feel, the optical and tactile impression and the electrical behavior. In addition, the safety mat often takes over Sealing function on the circuit board. Your mechanical lifespan is up to up to 10 million switching cycles makes it a long-lasting and almost maintenance-free input solution. It adapts to your design and is extremely flexible and space-saving.
force-displacement behavior
The force-displacement behavior A silicone keyboard can be customized to suit the requirements of the respective application. So are Actuation forces from 20g to 500g and Actuating paths (key travel) from 0,3 to 5,0mm is possible.
An short key stroke means the buttons are easy to press and require less effort to activate a button. This can be particularly advantageous for devices with many buttons to ensure quick and comfortable operation.
However, the key travel can also be adjusted depending on precision and tactile feedback requirements. In some applications a longer key travel be required to have one better feedback and to ensure a better tactile feeling when pressing the buttons. Therefore, key travel can vary depending on the application and is usually determined in the circuit design process to ensure the best possible user experience.
contact pills
The implementation options for the electrical contacts range from inexpensive, yet safe carbon print to high quality metal contact pills With a Current carrying capacity up to 2A.
The carbon print is often used with silicone safety mats to provide a cheap alternative to metal contacts, especially in applications with lower electrical conductivity requirements. The advantage of carbon printing is that it offers high flexibility and durability, which is ideal for use in electronic input devices. Another important feature is that it has a very low profile, which helps ensure that the buttons on the silicone keypads are flat and easy to press.
Circuit board
As a central component, it triggers a direct switching function on the circuit board underneath. In applications with high reliability gold-plated contact surfaces on the circuit board is preferred. Screen printed carbon is widely used because of its cost effectiveness and strong chemical resistance.
The contact surface the circuit board should be in every direction be at least 0,5 mm larger as the contact surface of the keyboard. For rocker buttons and buttons with metal domes, please submit the circuit board contact circuit to us.
Silicone Keypad Design
Silicone safety mats adapt to your design and are extremely flexible. Different button shapes and individual key colors, and multi-colored keyboard lighting can be easily implemented. We support and advise you in detail with the equipment and material selection of your silicone safety mat. Also the complete one development and construction We can provide you with a suitable silicone safety mat for your application.
Development
Thanks to our many years of expertise in the field of silicone keymats, we can offer you a comprehensive full service offer. Our engineers actively support you in the design and construction phase and in the selection of suitable materials.
Our product Designer can design your silicone keymat according to your wishes or revise the design or construction of an existing input solution. You have the choice of using our development and design services individually or as part of a more comprehensive support through to series delivery.
Our range of services includes sketching, conception, planning and preliminary construction, 3D/2D CAD design, realistic 3D renderings of product views and the creation of production documents such as technical drawings and parts lists. We can also produce prototypes using 3D printing or silicone casting.
We'd be happy to do that too complete assembly with matching Plastic housing and the connection technology.
