PROBLEM TO BE SOLVED: To provide a key switch device having good operability and capable of accurate key input by smoothing movement of the lower ends of two link members guiding vertical motion of a key top. SOLUTION: A locking shaft 7a of one link member 7 of a guide support member 6 for guiding support a key top 5 in the vertical direction is rotatably locked to a rotational locking part 5a of the key top 5, a locking pin 8b of the other link member 8 is slidably locked on a sliding locking part 5b of the key top 5, a locking pin 7a of the link member 7 is slidably locked between the inner periphery of an attaching part 1c integrally formed on a base board 1 and the upper surface of the base board 1, and a locking shaft 8a of the link member 8 is rotatably locked between the inner periphery of an attaching part 1a, formed integrally on the base board 1 and the upper surface of the base board 1. |
