PROBLEM TO BE SOLVED: To provide a luminous keying module enhanced in light utilization efficiency, reduced in thickness, reduced in cost, and further saved in power.SOLUTION: A luminous keying module includes a light emitting member, a light-guiding thin film circuit board, a keying layer, and an elastic layer. A circuit pattern is formed on the light-guiding thin film circuit board, and a plurality of thin film switches are provided on the circuit pattern. When a key of the keying layer is touched and pressed, the elastic layer is pressed by the key to be moved downwardly. Consequently, a thin film switch corresponding to a conductor of the elastic layer is triggered. |
