[0056] The bottom surface of the outer sidewall 12 extends outward to form several protruding portions 15. The several protruding portions 15 are evenly arranged in the radial direction of the outer sidewall 12 of the button 1, and the several protruding portions 15 are arranged in the corresponding mechanism of the housing 2. In this embodiment, there are four protruding portions 15. The several protruding portions 15 correspond to the cross key 14. The several protruding portions 15 correspond to a metal button 41 on the circuit board 4. One side of each protruding portion 15 extends along the radial direction of the button 1 and extends obliquely upward from bottom to top to form the elastic arm 16.

The two first extension portions 322 and the two second extension portions 323 pass through the through holes 42. The two hooks 326 are clamped to the lower surface of the circuit board 4, and the two positioning bumps 334 of the two side arms 33 are arranged in the two positioning holes 43. The circuit board 4 is fixed between the bottom surfaces of the two side walls 311 of the main body portion 31, the bottom surfaces of the two side arms 33 and the top surfaces of the two hooks 326 to prevent the circuit board 4 from shaking. The two side walls 311, the two connecting walls 312, the two openings 313, the two first extension portions 322, the two second extension portions 323, and the two side arms 33 of the main body portion 31 are symmetrical to each other, which facilitates automated assembly operations. Furthermore, a hollowed-out area 336 is formed between the two extension arms 331 and the connecting arm 335 of the side arm 33. The hollowed-out area 336 makes the side arm 33 more elastic and facilitates manual assembly operations. Therefore, the button structure 100 of the present utility model can facilitate automated assembly or manual assembly and achieve stable assembly.
