[0037] As Figures 1-4As shown, in the embodiment, the key 2 structure comprises a top shell 1, a key 2, a bottom plate 3 and a light touch switch 4; wherein the top shell 1 is provided with a positioning hole 101, which can be a round hole, a square hole or a special-shaped hole; the key 2 is arranged on the top side of the top shell 1, that is, the bottom side of the key 2 is in contact with the top side of the top shell 1, and the bottom side of the key 2 is provided with a positioning column 201 which is in consistent shape with the positioning hole 101; the positioning column 201 penetrates through the positioning hole 101 and is movably arranged in the positioning hole 101, that is, the positioning column 201 can move along the axial direction of the positioning hole 101 in the positioning hole 101, and the positioning hole 101 is used for limiting the side of the positioning column 201; the bottom plate 3 is arranged on the bottom side of the top shell 1, and there is a gap between the top side of the bottom plate 3 and the bottom side of the top shell 1, for example, a bottom support (not shown) is arranged on the bottom side of the top shell 1, and the side edges of the bottom plate 3 are placed on the bottom support to be supported by the bottom support; the light touch switch 4 is arranged on the bottom plate 3 and is arranged opposite to the bottom end of the positioning column 201; when the key 2 is pressed, the positioning column 201 presses the light touch switch 4 and can rebound through the light touch switch 4. The light touch switch 4 is an existing device and has a rebounding property, that is, when the positioning column 201 presses the light touch switch 4 under the action of external force, the light touch switch 4 drives the positioning column 201 to rebound when the external force on the positioning column 201 is removed. In the utility model, the key 2 is installed on the top shell 1 and is supported by the top shell 1, and the positioning column 201 on the key 2 can play a limiting and guiding role through the positioning hole 101, so as to prevent the key 2 from shaking greatly during pressing, and the pressed key 2 can also rebound through the light touch switch 4, and the shaking amplitude of the key 2 can be reduced through the cooperation of the positioning hole 101 and the positioning column 201 during rebounding. The key 2 structure provided by the utility model reduces the shaking amplitude of the key 2 under the action of external force through the cooperation of the positioning column 201 and the positioning hole 101, and improves the hand feeling when the key 2 is pressed.

[0038] As a further scheme, the top side of the top shell 1 is provided with a positioning groove 102, the positioning hole 101 is located in the positioning groove 102, and the bottom of the key 2 is arranged in the positioning groove 102. Specifically, the width of the positioning groove 102 is slightly greater than the width of the key 2, a plurality of keys 2 can be arranged in the positioning groove 102, and the positioning groove 102 is used for preliminarily limiting and positioning the key 2, so as to assist the key 2 to be quickly connected with the positioning column 201 during installation.
