The light-shielding bracket 3 is connected to the limiting bracket 2, and the plurality of first light-transmitting areas 31 are arranged in one-to-one correspondence with the plurality of light-emitting elements 11. The housing 5 is arranged on the outer wall of the limiting bracket 2. The button 4 extends along the preset direction and is arranged opposite to the light-shielding bracket 3. The button 4 is used to receive an external pressing force to drive the light-shielding bracket 3 to trigger the button switch 12. The button 4 extends along the preset direction, and the button 4 is provided with a second light-transmitting area having the same number as the first light-transmitting area 31 at intervals along the preset direction. The first light-transmitting area and the second light-transmitting area are arranged opposite to each other. Exemplarily, the button 4 can be made of a light-transmitting material such as transparent plastic. The light-emitting element 11 can be, but is not limited to, an LED lamp.

[0040] In short, for the button assembly provided in this embodiment, at least one button switch 12 and at least two light-emitting elements 11 are arranged on the circuit board 1 along the preset direction. The first light-transmitting areas 31 arranged along the preset direction are provided on the light-shielding bracket 3. The housing 5 with the button 4 is sleeved on the outer wall of the control module. The button 4 is used to receive an external pressing force to drive the light-shielding bracket 3 to trigger the button switch 12. The button 4 extending along the preset direction is arranged opposite to the light-shielding bracket 3. By pressing the button 4, the button switch 12 on the circuit board 1 can be activated. The light-emitting element 11 is located at the bottom of the button 4, so that the housing 5 does not need to be provided with mounting holes for installing the light-emitting parts, which not only reduces the number of holes punched in the housing 5 but also has the functions of the button 4 and the display lighting. Since at least two light-emitting parts are arranged along the preset direction, the button assembly can be controlled by the circuit board 1 to be lit according to the actual situation, meeting the function of segmental lighting and improving the user experience.
