Ends of the second supporting member 20 and the third supporting member 22 are correspondingly pressed into the clamping portions ( 160 , 162 , 164 ) of the keycap 16 to complete the assembly. Therefore, the button 1 of the present invention can fully save man-hours for manufacturing.

See Figure 4. FIG. 4 is a structural view illustrating a support member according to another embodiment of the present invention. As shown in FIG. 4 , the first support 30 and the second support 32 can surround the third support 34 . It should be noted that, after forming, the first support member 30 and the second support member 32 are respectively connected to the third support member 34 through a first joint portion 300 and a second joint portion 320 .

Alternatively, please refer to FIG. 5A and FIG. 5B . FIG. 5A is a perspective view illustrating a button 4 in a pressed state according to another embodiment of the present invention. FIG. 5B is a three-dimensional perspective view illustrating the button 4 in a standing state according to another embodiment of the present invention. The key 4 in FIG. 5A and FIG. 5B applies the support structure in FIG. 4 , where the third support 52 surrounds the first support 48 and the second support 50 .

It should be noted that, as shown in FIG. 5A and FIG. 5B , the lower surface of the keycap 46 can extend a first rib 466 and a second rib 468 respectively corresponding to the first connecting portion and the second connecting portion. After the cap 46 is connected to the plurality of supports, the first rib 466 and the second rib 468 are used to cut off the first connection part and the second connection part, so that the first support part 48, the second support part 50 and the third support part The support members 52 can be independently connected between the keycap 46 and the bottom plate 40 . In addition, the connection form between the two ends of the plurality of support members and the keycap 46 and the bottom plate 40 can be referred to the aforementioned paragraphs.

Similarly, the support structure in FIG. 4 can also be integrally formed during production to achieve modular production. Moreover, the keycap can also be assembled with the first support, the second support and the third support at the same time, that is, the ends of the first support, the second support and the third support can be correspondingly connected at the same time.
