To ensure our customers a wide range of customized silicone and rubber keyboards, Metalwo has production facilities in China.
A silicone or rubber 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 and rubber keypad on a membrane switch equipped with either polydomes or metal domes because it improves the keys significantly.
