In order to ensure the reliability of assembly, the key surface cover is buckled on the upper shell, two ends of the key surface cover extend downwards to cover two ends of the upper shell, the inner walls of the two ends of the key surface cover are provided with buckles, and two ends of the upper shell are provided with clamping sinking tables which are matched and clamped with the buckles; the two sides of the key surface cover are provided with downward extending clamping edges, the upper shell is provided with two clamping grooves, a group of clamping holes are formed in the clamping grooves, and a group of inserting blocks matched with the clamping holes are arranged on the clamping edges.

In order to ensure the fitting degree of the key surface cover, the transverse section and the longitudinal section of the key surface cover are of arc-shaped structures, and the key surface cover is attached to the upper shell.

Preferably, the thickness of the key surface cover is 0.5-0.6mm, so that a proper operating force is provided for the key.

The utility model has the beneficial effects that: according to the key structure, the key surface cover is arranged on the upper shell, the pressing sinking table is arranged, the button below the key surface cover is triggered by pressing deformation, so that corresponding circuit conduction is realized, the sealing performance of the button can be ensured, and the key clamping stagnation caused by dust accumulation in a gap of a traditional key structure is solved. The button face lid adopts nylon material, has high toughness and fatigue strength for button face lid is difficult to damage, long service life, and the cooperation of button face lid material selection and pressing down the heavy platform can realize better pressing handle. Meanwhile, the nylon material enables the surface of the key surface cover to be coated with various colors for decoration or textures, meets the requirements of manufacturers on different colors and textures, and improves the attractiveness of the remote control key.

The utility model will be described in more detail below with reference to the drawings and examples.
