    Abstract: A keyboard apparatus is provided for small and lightweight computers and the like. Keyswitches and a keyboard assembly comprise a sheet member having a plurality of key faces fixed thereon in a conventional keyboard arrangement. A plurality of cutouts are provided in the sheet member, partially surrounding each key face. A living hinge member is provided in the sheet member at one side of each key face. Each living hinge member includes a base section, an intermediate section, and a key face section. The former two and the latter two sections each interface at a living hinge. Depressing the key face causes the key face section to pivot about the living hinges to operate a corresponding set of electrical contacts, indicating operation of the key.
