Abstract:
A keyboard switch (100) of an X-frame structure (170) comprises a base (110), a static contact (120), a dynamic contact (130), an upper cover (140), a key (150) connected to the static contact (120) for controlling the movement of the dynamic contact (130), and a reset spring (160); and the keyboard switch (100) further comprises an X-frame structure (170) and an accommodation portion (180). The X-frame structure (170) comprises a first connection frame (171) and a second connection frame (172), and the first connection frame (171) and the second connection frame (172) are rotatably built in the accommodation portion (180) separately. The first connection frame (171) comprises a first balancing pole (171a) and two first connection portions (171b) mounted on the first balancing pole (171a) in a sleeving mode, and the second connection frame (172) comprises a second balancing pole (172a) and two second connection portions (172b) mounted on the second balancing pole (172a) in a sleeving mode. Convex columns (171c) are respectively disposed on the surfaces, of the two first connection portions (171b), that are opposite to each other. Round holes (172c) are respectively provided on the surfaces, of the two second connection portions (172b), that are opposite to each other. The convex columns (171c) can be inserted into the round holes (172c), so that two ends of the first connection frame (171) and two ends of the second connection frame (172) form two X-shaped structures. The keyboard switch (100) can prevent the keys (150) from being oblique and stuck, and the keyboard switch (100) is labor-saving in operation, convenient to use, and has good finger pressing sense of touch.
