Afterward, on the removable intermediate layer over the top surface, a hollowed region is formed through the removable intermediate layer and the light-shielding layer such that the translucent base layer is exposed within the hollowed region. Then, a colored translucent layer is partially formed to cover the hollowed region and the removable intermediate layer located on a peripheral of the hollowed region. Finally, the removable intermediate layer and the colored translucent layer covering the removable intermediate layer located on the peripheral of the hollowed region are removed together.

An illuminated touch key uses a chamfer structure of a light guide panel disposed on a sensing module or a light guide panel adjacent to a sensing module to guide light emitted by a light source to a hollow area of a keycap to emit light, thereby forming an illuminated pattern corresponding to the hollow area. Accordingly, a user can accurately find the location of the illuminated touch key according to the illuminated pattern. Since there is no need to add a light guide structure above the sensing module, the height of the illuminated touch key will not be increased, such that it is conducive to make the illuminated touch key thinner.

Abrégé
A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, a pivot of two supports overlaps base holes of the supports along the pivot axis. For another example, each of supports has support arms extending non-parallel to the pivot axis. The free end of each support arm is connected to a base plate. For another example, among a plurality of pivotally-connecting structures between supports, at least one includes a fully-open pivot hole, achieved by two opposite hooks, and at least one includes a semi-open pivot hole, achieved by two opposite hooks and a blind hole. A long rectangular keyswitch structure includes a keycap and any of the above mechanisms. The distance from a sliding hole of one support to an adjacent keycap long side is greater than the distance from a holder hole of another support to another adjacent keycap long side.

A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, vertical projections of a sliding hole, a holder hole, and a base hole of supports overlap in a short side direction. For another example, vertical projections of a sliding hole, a holder hole, and a pivot hole of supports overlap in the short side direction. For another example, within the coverage range of a dome hole formed by supports in a long side direction, the supports do not have a structure connecting with other components. For another example, within the coverage range of two arms on opposite sides of the dome hole, there are more than 8 connection portions on the supports for connecting with a keycap and a base plate. For another example, the width of the arm is 0.8 to 2 times the length of the arm.

Abrégé
A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

Abrégé
An illuminated keyswitch includes a keycap, a pair of frames adapted to support the keycap in an up-down movement, the pair of frames disposed corresponding to each other and substantially rotatably coupled to each other to define an inner space under the keycap, a pair of elastic members connecting the pair of frames to be located at two opposite sides of the inner space, respectively, and an illumination light source disposed between the pair of elastic members in the inner space and adapted to provide an illumination light. During the up-down movement of the keycap, a vertical projection of the pair of frames surrounds the inner space without interfering therewith, so the illumination light passes the inner space to illuminate the keycap.

Abrégé
A backlight keyboard includes a first keyswitch, a first backlight source, a light guide plate and a first board having first and second holes. The light guide plate is applied to the backlight keyboard and a second backlight keyboard including a second keyswitch, a second backlight source and a second board having third and fourth holes. The second keyswitch on the second backlight keyboard is shifted transversely relative to the first keyswitch on the backlight keyboard to make the first and fourth holes have a first overlapping area. The light guide plate has a first dot structure corresponding to the first and third holes and a second dot structure corresponding to the second and fourth holes except the first overlapping area for guiding light to symbols on the first and second keyswitches. The first dot structure is less than the second dot structure in dot intensity.

Abrégé
A keyswitch structure includes a keycap support mechanism and a keycap that is supported by the keycap support mechanism in a vertical direction. The keycap support mechanism includes a base and two supports. The base has two sliding slots. Each sliding slot has an opening in a horizontal direction and an obstruction block at the opening. The horizontal direction is perpendicular to the vertical direction. Each support has a sliding portion and a linkage portion. The sliding portions slide parallel to the horizontal direction in the sliding slots correspondingly. The obstruction block prevents the corresponding sliding portion from disengaging from the corresponding sliding slot. The two linkage portions push against each other in line contact, so that the two supports are mutually driven through the two linkage portions.
