摘要： An illuminated keyswitch structure with an illuminating module includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.

摘要： A keyswitch backlight structure includes a light-guiding layer, a reflective layer, and a transparent adhesive layer. The light-guiding layer has a bottom surface, a light-emitting surface opposite to the bottom surface, and a surface microstructure formed on the light-emitting surface. The reflective layer is disposed opposite to the bottom surface. The transparent adhesive layer is closely attached to and between the reflective layer and the light-guiding layer corresponding to the surface microstructure. An illuminated keyswitch structure includes base plate, a keycap, a supporting mechanism, and the above keyswitch backlight structure. The keyswitch backlight structure and the base plate are stacked. The supporting mechanism is connected to and between the base plate and the keycap for lifting the keycap relative to the base plate. Light entering the light-guiding layer exits the light-guiding layer through the light-emitting surface to illuminate a transparent indication area of the keycap.
