Silicone keyboards
To ensure our customers a wide range of customised silicone keyboards, Metalwo has production facilities in
China. A silicone keypad can be created in many designs with individual colours and surface coatings, in accordance with design
requirements. Furthermore, it is often an additional advantage to use the silicone keyboard on a membrane switch equipped with
either polydomes or metal domes because it improves the keys significantly.
