The button holder 30 has a main body portion 301 having a circular sheet shape and a plurality of fixing posts 302 projecting upward from the upper surface of the main body portion 301. When the key holder 30 is assembled to the rotary holder 20 from the bottom up, the main body portion 301 passes upward through the main through hole 201 and is connected to the circuit board 10 through a plurality of opened through holes (FIG. 2). The fixing posts 302 are respectively passed upward through the secondary through holes 202 and are disposed at corresponding positions on the back of the main body portion 301. The raised protrusions correspond to the corresponding contacts of the circuit board 10. By designing the button holder 30 to be disposed at the center of the rotating bracket 20, the button bracket 30 is fixed and fixedly assembled with the circuit board 10, and serves as a mounting base for the rotating bracket 20, the shift fork 203, and the rotary cover 40. Among them, the shift fork 203 and the rotating surface cover 40 are rotated relative to the rotating bracket 20. The rotating bracket 20 is also stationary, and is controlled by the button cover 50 pressing to trigger the contact of the circuit board 10.

The secondary through hole 202 has an arc structure with a larger cross section than the corresponding fixed post 302, and the secondary through hole 202 is centered on the rotating bracket 20. The above secondary through hole 202 is designed because the secondary through hole 202 on the rotating bracket 20 and the fixing post 302 on the button bracket 30 require an interference fit, and at the same time, the fixed point of the circuit board 10 with the rotating bracket 20 and the button bracket 30, It is not completely guaranteed that there is no error. Once there is an error or needs to be fine-tuned, the arc-shaped hole can meet the requirements appropriately. Preferably, the arcuate through hole and the fixing post 302 may be four, respectively.
