A keyswitch includes a keycap, a lifting mechanism and a bottom board. The lifting mechanism is movably connected under the keycap and has a connection shaft. The bottom board has a hole structure and is located under the lifting mechanism. A hook structure is bent from a side wall of the hole structure toward the connection shaft. The connection shaft is movably connected to the hook structure to make the keycap movable upward and downward relative to the bottom board via the lifting mechanism. A first reinforcement area extends in a tapered manner outward from a bent side of the hook structure along the side wall.

Systems and apparatus for controlling light emitted from light sources that backlight multicharacter keycaps, resulting in different characters being displayed on the keycaps. A system may include: a processor, and a keyboard having one or more backlit keyboard keys, where at least one of the one or more backlit keyboard keys includes: a socket comprising a light source, and a keycap coupled to the socket. The keycap may include: a first color filter corresponding to a first character, where the first character is displayed on the keycap when a color of light emitted from the light source matches the first color filter, and a second color filter corresponding to a second character, where the second character is displayed on the keycap when the color of the light emitted from the light source matches the second color filter.

A keyboard assembly and a keyboard device are disclosed. The keyboard device includes a keyboard assembly and a support member. The keyboard module is provided with a surface shell and a key module, and the key module is connected to the surface shell; the key module is provided with at least one key, and a light-transmitting space is formed between the key and the surface shell; the light module is provided on one side of the key module, and the light emitted by the light module is projected along the light-transmitting space; the light module is provided with a plurality of lamp beads, which are independent of each other and can emit the same or different light.
