摘要

The keyboard has a front film (1), spherical humps (9) applied to the front film by adding additional material at at least some key locations (7) and an elevation enclosing the spherical humps. The elevation is formed by a formation in the upper surface of the front film material. The elevation fully encloses the periphery of the spherical humps.
