PROBLEM TO BE SOLVED: To provide a key switch device having satisfactory key operability for secure key input by smoothing the moving operation of lower ends of two link members for guiding a key top in the vertical directions. SOLUTION: This key switch device is formed by punching a board 1 made of a plastically deformable metal raw material, cutting unnecessary parts 1b, pressing residual parts 1a, 1c for deformation, projecting the fitting part 1c as a slide lock part and the fitting part 1a as a turn lock part, locking a lock pin 7a of one link member 7 of a guide support member 6 for guiding and supporting the key top 5 in the vertical directions, with the fitting part 1c integrally formed with the board 1 freely slidably, and while locking a lock shaft 8a of the other link member 8 with the fitting part 1a projected from the board 1 freely turnably. |
