PROBLEM TO BE SOLVED: To provide a key switch device in which each of links does not undergo a bending stress where a key top is in a pressed state, and in which each of the links can be surely prevented from cutting. SOLUTION: In the key switch device of the present invention, front and back portions 303 are formed at a sliding groove of a sliding-engaging portion 116 formed on a lower surface of a key top 102. Where the key top 102 is in a non-pressed state, second engaging pins 111A and 111B are in contact with the front portion to control a maximum rising position of the key top. Also, a sliding groove of a sliding-engaging portion 128 in a holder member 107 has a front portion 300 and a back portion 301. Where the key top 102 is in a non-pressed state, second engaging pins 114A and 114B are in contact with the front portion 300 of the sliding groove in the second link 105 to control a maximum rising position of the key top 102. On the other hand, where the key top 102 is in a pressed state, the second engaging pins 111A and 111B of the first link 104 are not in contact with the back portion of the sliding groove of the sliding-engaging portion 116, and the second engaging pins 114A and 114B are not in contact with the back portion 301 of the sliding groove in the sliding-engaging portion 128. |
