The light-emitting element 40 can be an LED or other light-emitting element.

[0036] like Figure 5As shown, the button housing 21 includes an upper shell 211 and a lower shell 212. The top of the upper shell 211 has the aforementioned through-hole 23. The positioning post 25 is located on the lower shell 212. After the lower shell 212 and the upper shell 211 are fastened together, they form a receiving cavity. The receiving cavity is provided with a pressing shaft 22 and an elastic reset mechanism that resets the pressing shaft 22 upwards. The side wall of the receiving cavity forms a limiting slide 213. A limiting block 221 corresponding to the limiting slide 213 is formed on the outer side of the pressing shaft 22. The limiting block 221 is slidably connected to the limiting slide 213 and guides the movement of the pressing shaft 22. In this utility model, the upper shell 211 is provided with a downwardly extending hook 214, and the lower shell 212 is provided with a locking block 215 corresponding to the hook 214. The upper shell 211 is fastened to the lower shell 212 by hooking the hook 214 onto the locking block 215. The elastic reset mechanism is a compression spring 26, but other components with elastic reset function can be selected instead in actual use.

[0037] Specifically, the lower shell 212 is provided with a first clearance groove 216 corresponding to the lower part of the light guide 30, and the upper shell 211 is provided with a second clearance groove 217 corresponding to the upper part of the light guide 30.

[0039] To facilitate the installation and removal of the light guide 30, guide slopes are provided on both the upper and lower sides of the protrusion 32. By providing guide slopes on both sides of the protrusion 32, when it is necessary to remove the light guide 30, it can be pushed upwards, allowing it to slide out of the light-transmitting groove 24 by the upper guide slope, thus freeing it from the restriction of the third step. Conversely, when it is necessary to install the light guide 30, it can be pushed downwards, allowing it to be inserted into the light-transmitting groove 24 by the guiding action of the lower guide slope. To facilitate the installation of the key switch 20 onto the main control circuit board 10 of the keyboard, a third clearance groove 33 is provided on the outer side of the light guide 30, which corresponds to the latching position on the keyboard.

During assembly, the surrounding plate and the cross-shaped connecting post are exposed at the through-hole 23 at the top of the upper shell 211. It should be understood that in actual use, a scheme without a surrounding plate can also be adopted.

[0041] In summary, this utility model, by setting two symmetrically distributed light-transmitting slots and a light guide component separately installed within the light-transmitting slots from the housing, allows for the replacement of light guide components of different colors to achieve different colors of light emission as needed. Alternatively, the light guide components can be removed, allowing the light from the luminous component to directly pass through the light-transmitting slots, thus achieving different lighting effects and meeting the personalized needs of different users. Furthermore, by setting luminous components on the main control circuit board that correspond one-to-one with the positions of the two light-transmitting slots, the uniformity of light from the light guide components is improved, enhancing the keyboard's lighting effect and improving the user experience.
