[0002] With the development and progress of society, computers have been widely used in education, medical treatment, entertainment, and business. The function keys on the computer can realize functions such as power on, restart, adjust volume, adjust brightness, and adjust direction. The computer control motherboard and function keys are integrated in the body. Usually, the function switch is set on the control motherboard inside the machine, and buttons are set on the outer surface of the body. The user triggers the switch on the control motherboard inside the machine by pressing the button, thereby realizing the key control function.

[0003] In the prior art, function switch buttons are usually installed by screws and hot melt. The screw installation method is limited by the installation space, and it is very inconvenient to use screws when the space is small. Although the hot melt installation method can solve the problem of limited installation space, it is limited by the material of the button mounting plate. For example, when the button mounting plate is made of metal, it cannot be installed by hot melt. Hot melt installation is also easy to fall off, resulting in an unstable installation. Moreover, the hot melt process is irreversible. After hot melt, the button can only be destructively disassembled, and after-sales maintenance of accessories is inconvenient.
