摘要： A system may comprise a printed circuit board (PCB) including a top surface, and a bracket including a top surface configured to receive and couple to a key switch and a bottom surface including at least two protrusions that extend normal to the bottom surface of the bracket. The bracket can be configured to mount to the PCB such that the bottom surface of the bracket is coupled to the top surface of the PCB, and the at least two protrusions may each include conductive leads that couple to the top surface of the PCB. The bracket is configured to only cover a portion of a bottom surface of the key switch when coupled to the key switch. An LED can be mounted to the top surface of the PCB, laterally adjacent to the bracket, and under the key switch at a location not covered by the bracket.

摘要： In some embodiments, a keyboard key structure includes: a substrate; a key switch, which includes a top housing, a bottom housing. and a key stem. The top housing covers the key stem and is coupled to the bottom housing to form a cavity. The bottom housing is coupled to the substrate. The keyboard key structure further include a keycap including a light transmissive region, the keycap being configured to be coupled to the top housing of the key switch; and a light guide coupled to one side of the cavity of the key switch, the light guide comprising: a flat bottom surface; and a flat top surface wider than and parallel to the bottom surface. The top surface includes uncontinuous, trapezoidal-shaped Fresnel structures at end portions at both ends thereof. A light emitting element is coupled to the substrate and disposed under the bottom surface.
