Keyboards can be supplied on request in silicone rubber — with or without inserts in conductive rubber — to be used on rigid printed circuit or on the polyester membrane. The silicone rubber is one of the most stable elastomers with excellent resistance to temperature and aging, it doesn’t deform with compression and it is chemically inert, and immune to corrosion and decay. It also has excellent resistance to alkalis, oils and acids. The silicone rubber is an electronically insulating material that, by the addition of conductive carbon particles, becomes conductive. Features: usage temperature -40 ° to +150 ° C, storage temperature -48 ° to +175 ° C, contact resistance of 200 ohms max, preload 0.2 mm. Silicone rubber keyboards can be made in: silicone aesthetic rubber in one or more colours, screen-printed on the outside of the button with a protective UV coating, gray rubber with button cover support. The development of electronics has seen increasing demand for silicone rubber keypads with excellent durability and tactile properties, low cost and with a wide range of applications.
