Expansion joint for keyboard dome sheets |
摘要 |
A dome sheet molded integrally from elastomeric rubber or plastic material is divided into two or more planar sheet sections, each containing a plurality of raised domes used in keyboard actuation. The adjacent sections are integrally joined by a hinged web having walls extending outward from the plane of the sheet. The web permits translational and angular movement of the adjacent sheet sections as required to properly position them between mating keyboard parts during keyboard assembly. This assures more accurate alignment between keyswitch actuators and keyboard switching elements associated with the individual domes about the dome sheet.
