Patent ID: 8690369

Claim:
A luminous keying module of a handheld device, said luminous keying module comprising: at least one light-emitting element for providing light beams; a light-guiding membrane wiring board for receiving and transferring said light beams from said at least one light-emitting element, wherein a circuit pattern is formed on said light-guiding membrane wiring board, and said circuit pattern comprises plural membrane switches, wherein each of said membrane switches comprises a first conductive part and a second conductive part, and said first conductive part and said second conductive part are separated from each other; a keying layer comprising plural keycaps corresponding to respective membrane switches; and an elastic layer arranged between said light-guiding membrane wiring board and said keying layer, wherein plural conductive structures are formed on a bottom surface of said elastic layer, wherein each conductive structure is aligned with a corresponding membrane switch, and each conductive structure and said corresponding membrane switch are separated from each other by a spacing interval, wherein when any of said plural conductive structures is contacted with said corresponding membrane switch, said first conductive part and said second conductive part of said corresponding membrane switch are electrically connected with each other.
