The elastic arm portion 223 includes an upper surface 2231 that is aligned with the first surface 2211 of the operation portion 221 and a lower surface 2232 that is aligned with the second surface 2212 of the operation portion 221, and an elasticity is defined between the upper surface 2231 and the lower surface 2232. In the thickness direction of the arm portion 223, the movement of the operation portion 221 from the first position to the second position causes the elastic arm portion 223 to be bent downward to form a state in which the lower surface 2232 is pressed and the upper surface 2231 is pulled, that is, in the operation portion 221 When depressed, the elastic arm portion 223 is deformed downwardly.
在本实施例中，弹性臂部223的宽度(即在垂直于延伸方向和厚度方向的方向上的尺寸)大于等于2.5mm，厚度大于等于0.7mm。如此设置，有利于加强弹性臂部223的弹性，进而使得按压手感更好。In the present embodiment, the width of the elastic arm portion 223 (i.e., the dimension in the direction perpendicular to the extending direction and the thickness direction) is 2.5 mm or more and the thickness is 0.7 mm or more. Provided in this way, it is advantageous to reinforce the elasticity of the elastic arm portion 223, thereby making the pressing feel better.

By the eccentric arrangement of the switching element 21 and the operation portion 221, a sufficient space is left under the operation portion 221, so that other elements such as a light-emitting element or the like can be disposed under the operation portion 221. In the present embodiment, the light-emitting elements are disposed directly under the operation portion 221 of the button 2, and thus it is ensured that the light at each position of the operation portion 221 is observed to be uniform in symmetry. Optionally, the switching element 21 is at least partially located outside the orthographic projection area of the first surface 2211 so that the light emitted by the light emitting element is irradiated to the operating portion 221 as much as possible, so that when viewed from the outside of the electronic device, Light that is uniformly transmitted outward from the opening area corresponding to the operation portion 221 on the panel of the electronic device can be observed.
在本实施例中，开关元件21的中轴线与开关致动元件22的安装部222之间的距离大于操作部221的中轴线与安装部222之间的距离，即开关元件21设置在操作部221的远离安装部222的一侧，如此，无论按压操作部221的哪个部位，都能获得较好的按压手感，且可保证按压在第一表面2211的任何位置都可获得较好的操作灵敏度。In the present embodiment, the distance between the central axis of the switching element 21 and the mounting portion 222 of the switch actuating element 22 is greater than the distance between the central axis of the operating portion 221 and the mounting portion 222, that is, the switching element 21 is disposed at the operating portion. The side of the 221 that is away from the mounting portion 222, so that no matter which part of the operating portion 221 is pressed, a better pressing feel can be obtained, and it is ensured that a good operational sensitivity can be obtained at any position of the first surface 2211. .

After the operating portion 221 is pressed a certain distance, the limiting structure is The 2213 touches the PCB board 13 located under it, preventing the operation portion 221 from being strongly pressed. It can be understood that the distance between the limiting structure 2213 and the PCB board 13 is greater than the distance between the switching element 21 when the operating portion 221 is in the first position, otherwise the operating portion 221 cannot touch the switching element 21. Moreover, when the limiting structure 2213 is located at the elastic arm portion 223, the light-emitting element can be placed to ensure that the light-emitting element is located below the operating portion 221. Of course, not limited to the above design, the limiting structure 2213 may also be formed on the second surface 2212 of the operating portion 221.
