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.
Automotive silicone keymat

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.

A pair of 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.

Ideal for backlit keyboards

Highly transparent silicone keymat

Highly transparent silicone keypads are an interesting option, especially for backlit keyboards. To date, transparent silicone safety mats have tended to be milky, which leads to scattering losses from the light source. Highly transparent safety mats, on the other hand, offer one minimal light scattering, which means that the luminous flux almost completely reaches the surface. This makes them particularly interesting for brightly lit working environments or for use in daylight. In addition, the integration of light channels can be dispensed with, creating a closed surface.

In addition, such a silicone safety mat offers extensive protection of the underlying electronics from dust and moisture. The lighting can also be easily implemented into existing component components using status LEDs, so that fewer individual components are required. The material is also particularly suitable for switch mats with key caps made of plastic or metal, as well as paint finishes in the night design.
