Patent ID: 7844309

Claim:
An apparatus comprising a bendable elastomeric keymat, a cover including a recess, and a substrate located within the cover comprising a plurality of key switches, wherein, said keymat comprises a plurality of lips located at and extending outward from edges of said keymat toward a rim of the recess and a plurality of pressure transmitters extending from an interior surface of the keymat, and said cover comprises a plurality of indentations configured to receive said plurality of lips, wherein the bendable elastomeric keymat comprises elastic properties and is configured so that an entirety of the bendable elastomeric keymat bends to outwardly force the lips toward the rim of the recess and into the plurality of indentations on the cover to attach the edges of the keymat to the cover and said indentations are located at edges of the recess for removably mounting said keymat, the cover also includes a plurality of apertures through which the plurality of pressure transmitters pass to activate the plurality of key switches and a plurality of locking parts extending from an interior surface of the recess adjacent the indentations so that the plurality of locking parts interface with the lips of the keymat and, along with the elastic properties of the keymat, force the lips of the keymat into the indentations of the cover.
