A thin keyboard switch comprises a keycap (7), a housing (1), an elastic body (2), an elastic contact body (3), a balancing frame (4), and a base (5) disposed on a printed circuit board (PCB). A base groove (54) fitting the elastic body (3) is provided at the center of the base (5), the elastic contact body (3) is disposed at the bottom portion inside the base groove (54), and the elastic contact body (3) is electrically connected to the PCB. The elastic body (2) located in the base groove (54) is disposed on the elastic contact body (3). The balancing frame (4) is mounted on the external side of the base (5), and the balancing frame (4) is located between the base (5) and the housing (1). The housing (1) and the base (5) are disposed in a tightly gripping manner. The elastic body (2) protrudes from the housing (1) and is connected to the keycap (7), and the keycap (7) is mounted on the balancing frame (4). By means of the foregoing structure, the thickness of the keyboard is greatly reduced, and an ultrathin effect of the keyboard is achieved; the usage effect is good, and meanwhile, the keyboard has aesthetic appeal. |
