Abstract
The key consists of an upper part or head (1) of plastics, on a base (2) of silicone rubber. Head (1) has external face (3) which is pressed to actuate the key, and internal face (4) in contact with silicone base (2). Head (1) contains multiple holes (5,6,7,8) which pass through internal face (4) and communicate with base (2) without passing through external face (3) of head (1), allowing penetration of silicone into the interior of head (1), fixing it to base (2). The holes can be made by moulding or machining. In a keyboard, all the silicone bases (2) are moulded as a single part.
