The flexible skin layer can be made of at least one of polyurethane or polyester. The keyframe module can include a metal support plate for conducting a signal and a key structure situated over the metal support plate for providing tactile feedback when the key frame module is actuated. A plastic key cap structure can be situated over the dome structure. The flexible skin layer can be coupled to the plastic key cap. The key structure can be a dome structure where the flexible skin layer is a rubber or a fabric skin layer. The key structure can be a scissors key structure where the flexible skin layer is a rubber skin layer. Flexible key caps can be molded to the flexible skin layer.
