[0056] In an embodiment, the ejector pin 26 is integrally formed with the light transmission piece 23. It can be understood that the ejector pin 26 is integrally formed with the light transmission piece 23 to enhance the overall structural rigidity and simplify the number of parts, thereby reducing the complexity of assembly of the button 100. In addition, since one end of the ejector pin 26 abuts against the operation switch, the light transmission piece 23 can be more stable in the through hole, reducing the need for additional fixing measures for the light transmission piece 23 and simplifying the assembly process.

[0057] In an embodiment, the light transmission area 22 is located at the bottom of the light shielding shell 2 corresponding to the position of the light source 121. It can be understood that the light transmission area 22 is arranged at the bottom of the light shielding shell 2 corresponding to the position of the light source 121, so that the light can reach the light transmission area 22 from the light source 121 in the shortest path. This design reduces the loss of light during transmission, improves the transmission efficiency and utilization rate of light, ensures the brightness and clarity of the light transmission area 22, and is more conducive to users to quickly find the position of the button 100, thereby improving the user experience.

[0058] Specifically, the light transmission area 22 is located directly below the light source 121.
