Silicone keyboards

General:

At our production facility in China, we integrate silicone keypads with a membrane switch into a final operating panel to ensure the customer a perfect and good looking solution. A silicone mat can be created in many designs with individual colours and the surface coatings can be finished in accordance with design requirements.

However, it is often an additional advantage to use the silicone keyboard on a membrane switch equipped with poly domes or with metal domes because it improves the keys.
