The key 1 shown in FIGS. 1 and 4 is a multiple key and a butterfly lift mechanism is used as an example, but the key 1 according to the preferred embodiment of the present invention is not infinite, and can be implemented in the general key of non-multiple keys. The keys can also be implemented in a scissor lift mechanism.

As shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , a key 1 according to a preferred embodiment of the present invention includes a key cap 11 , and a key connecting component located below the key cap 11 and connected to the key cap 11 18. The key connection assembly 18 also includes a bottom plate 10 and one or more brackets 13 . The bracket 13 of the button 1 shown in FIGS. 1 and 4 is one of the components of the butterfly lift mechanism 12 , and includes two pairs of brackets 13 .

The bottom plate 10 includes a main board body 101 , a positioning structure 102 , a limiting structure 103 and abutting fins 104 . The upright positioning structure 102 is formed on the horizontally arranged mainboard body 101 . The positioning structure 102 defines a front side FS and a rear side BS opposite the front side FS. The positioning structure 102 has a top 1020 and positioning sidewalls 1022 .

An upright limiting structure 103 is formed on the main board body 101 and is opposite to a positioning structure 102 . The limiting structure 103 and the positioning structure 104 generally extend in parallel along a limiting direction R. The limiting structure 103 and the positioning structure 104 may be located on the same straight line, or may be offset and parallel to each other. The limiting structure 103 includes a hook-shaped portion 1032 extending toward the opposite positioning structure 102 . A gap 1011 and a through hole 1010 are formed between the positioning structure 102 and the limiting structure 103 to communicate with each other up and down. A notch 1011 is defined above the through hole 1010 . The notch 1011 is formed between the hook portion 1032 and the top 1020 of the positioning structure 102. The notch 1011 and the through hole 1010 allow the positioning structure 102 and the opposite limiting structure 103 to be penetrated along a bearing direction A. The limiting direction R and Bearing direction A is vertical. The limiting structure 103 has a limiting sidewall 1034 facing the positioning sidewall 1022 . The main body 101 also has an accommodating hole 1014 and a bearing end 1015 , both of which are located at the front side FS.

The abutting tab 104 is located in front of the limiting structure 103, but the bending direction of the abutting tab 104 is not limited. The upper curved surface 1044 of the abutting tab 104 may face the bearing direction A, or may face the actuating shaft 134 (vertical bearing direction A or parallel limit direction R). The abutting blade 104 has an abutting wall surface 1042 facing the actuating shaft 134 or facing the positioning side wall 1022 , that is, the abutting wall surface 1042 is perpendicular to the bearing direction A or parallel to the limiting direction R. In FIG. 5 , the abutting wall surface 1042 is perpendicular to the upper curved surface 1044 , the upper curved surface 1044 faces the bearing direction A, and the abutting wall surface 1042 is parallel or faces the limiting direction R.

The keycap 11 is placed above the bottom plate 10 and can move vertically relative to the bottom plate 10 . The bracket 13 includes a bracket body 132 and an actuating shaft 134 . The bracket body 132 includes an upper bracket portion 1322 and a lower bracket portion 1324 .

In other embodiments, the shaft diameters may also be reversed, that is, the main shaft diameter d1 of the actuating shaft 134 is smaller than the outer shaft diameter d2 of the outer shaft portion 136 . The key point is that in different embodiments of the present invention, the main body 101 of the bottom plate 10 can provide the receiving hole 1014 to receive at least a part of the actuating shaft 134 (the part with the larger shaft diameter), and make at least another part with the smaller shaft diameter close to Abut on the bearing end 1015, whichever is on the outside. In this way, the larger diameter portion of the actuating shaft 134 can be limited by the accommodating hole 1014, and the bearing end 1015 is located on the side of the accommodating hole 1015 for abutting against the smaller diameter portion of the actuating shaft 134. Even if the abutting tabs 104 are removed, the actuating shaft 134 with changing shaft diameter, the accommodating hole 1014 and the bearing end 1015 can eliminate the unnecessary connection gap caused by the assembly interference defect of the actuating shaft 134 .

The elastic actuating element 16 is disposed between the keycap 11 and the bottom plate 10 and above the switch 152 . When the keycap 11 is pressed and moved to the pressed position, the elastic actuating element 16 is deformed and the switch 152 is triggered. When the keycap 11 is released, the elastic actuating element 16 provides the restoring force required for the keycap 11 to return to the unpressed position, and the switch 152 is released. In the example shown in FIG. 2 , the elastic actuating element 16 is disposed between the two sets of butterfly lift mechanisms 12 . The two connecting members 17 are respectively connected to the brackets 13 of different sets of butterfly lift mechanisms 12 , so that the two sets of butterfly lift mechanisms 12 operate in the same way.
