The substrate 100 is arranged below the housing 400 and fixed to the bottom surface of the housing 400. The encoder 300 and the light emitting device 200 are both fixed to the top surface of the substrate 100, and the encoder 300 and the light emitting device 200 are both located on the inner side of the housing 400, and the housing 400 plays a role of isolating and protecting the encoder 300 and the light emitting device 200. The light guide ring 500 is an annular structure, which is located on the inner side of the housing 400 and fixed on the housing 400. The knob ring 600 is located on the inner side of the light guide ring 500 and connected to the encoder 300. The display screen assembly 700 is located on the inner side of the knob ring 600 and connected to the substrate 100. Thus, at the top opening of the housing 400, the display screen assembly 700, the knob ring 600, the light guide ring 500 and the housing 400 can be arranged in sequence from the inside to the outside along the radial direction. The knob ring 600 is configured to be rotatable relative to the light guide ring 500 and the display screen assembly 400, so that the light guide ring 500 and the display screen assembly 400 do not interfere with the rotation of the knob ring 600, ensuring that the knob ring 600 can realize the function of a knob. The display screen assembly 400 can display information such as relevant parameters, working status and menus of the electrical product. The light guide ring 500 is used to guide light. The light emitted by the light-emitting device 200 can be guided by the light guide ring 500 and then emitted out of the housing 400, thereby forming an aperture on the surface of the entire knob assembly, which can enhance the visual effect. The user can quickly find the position of the knob assembly through the aperture, making it convenient for the user to use the knob assembly in poor lighting conditions, thereby improving the user experience.
