Key switch structure and keyboard

The utility model relates to the field of keyboards, and discloses a key switch structure, which comprises a cover body, a moving assembly, a base and an elastic sheet assembly, the base and the cover body are matched to form a hollow cavity, one end of the moving assembly and one end of the elastic sheet assembly are arranged in the cavity, and the other end of the moving assembly extends out of the cover body. The elastic piece assembly comprises a first elastic piece, a second elastic piece and a ground wire elastic piece, when the moving assembly moves in the vertical direction, the first elastic piece, the second elastic piece and the ground wire elastic piece can be driven to be sequentially separated in the vertical direction, and therefore the first-order pressure triggering function and the second-order pressure triggering function can be achieved when pressing force of different sizes is applied; in other words, two or more triggering processes can be achieved according to the magnitude of the press
