摘要： A keyboard includes a plurality of keyswitches, a plastic baseplate, and a membrane circuit board. Each keyswitch has a keycap, a lifting mechanism and an elastic member. The lifting mechanism is movably connected to the keycap. The elastic member abuts against the keycap. The plastic baseplate has a first hole formed corresponding to each elastic member and has a connecting structure corresponding to each lifting mechanism. The connecting structure is movably connected to the lifting mechanism to make the keycap movable relative to the plastic baseplate. The membrane circuit board is disposed under the plastic baseplate. Each elastic member passes through the first hole on the plastic baseplate to be disposed on the membrane circuit board. When the keycap is pressed, the elastic member deforms downward to trigger the membrane circuit board. When the keycap is released, the elastic member returns the keycap to its original position.

摘要： A keyswitch structure includes a lift mechanism and a keycap. Two supports of the lift mechanism support the keycap. There can be a spring structure connecting the two supports for driving the two supports to lift the keycap. The lift mechanism defines a central space extending through the whole lift mechanism in a vertical direction. The spring structure does not enter the central space. The two supports abut against and constrain each other through corresponding structures, to mutually rotate with respect to a rotation axis. The keyswitch structure can include a switch. The switch includes an intermediate support, detachably abutting downward against the lift mechanism or the keycap, and a resilient part, detachably abutting downward against the intermediate support. In the process of pressing the keycap, the intermediate support is separated from the lift mechanism or the keycap, so that the contact force of the switch can be maintained constant.

摘要： An illuminated keyswitch structure and an illuminating module thereof are provided. A base plate has an opening. The illuminating module includes a drive circuit board, having a face reflector and at least one dot reflector disposed thereon, a spacer adhered on the drive circuit board and having a through hole and an adhesive-less clearance fringe at least partially surrounding the through hole, a light-emitting part disposed on the drive circuit board and proximate to the face reflector and the dot reflector, and a translucent covering structure covering above the light-emitting part and including a reflective layer. The reflective layer reflects off light from the light-emitting part, and the face reflector and/or the at least one dot reflector reflect light to pass through the through hole of the spacer and then illuminate upward through the translucent covering structure and further through the opening of the base plate.

摘要： A backlit-module-embedded illuminated keyswitch structure includes a baseplate, a mask film disposed below the baseplate and having a first coating for substantially reflecting a light and a second coating for substantially blocking the light, a light guide sheet at one side of the mask film and having a light source hole, and a reflective layer at one side of the light guide sheet opposite to the mask film. The second coating includes a second main coating region and a plurality of second coating sub-regions, which extends outward from the second main coating region and is arranged along the periphery of the second main coating region to form a plurality of intermediary regions therebetween. The first coating and the second coating are disposed right above the light source hole. The first coating is at least partially located in the intermediary regions.

摘要： A keyswitch structure includes a base plate, a keycap, and a support mechanism. The support mechanism supports the keycap above the base plate. An outer support of the support mechanism includes a reinforcing body and a connecting structure fixed on the reinforcing body. The outer support is connected to the base plate and the keycap through the connecting structure. In an embodiment, the reinforcing body has two openings. Two inner supports of the support mechanism are pivotally connected to the connecting structure and are located in the two openings, respectively. In another embodiment, the reinforcing body as a whole extends along a plane. The reinforcing body has a bent fringe, which is inserted into the connecting structure and is not perpendicular to the plane.

摘要： A lighting keyboard includes a backlight module and at least one keyswitch. The backlight module includes a lighting unit, a light guide panel, and a lighting board for illuminating a keycap of the keyswitch. The light guide panel includes a panel hole to accommodate the lighting unit. The light guide panel further includes plural slots intervally surrounding the lighting unit. The lighting board includes a micro-structure region facing toward the light guide panel. Each of the slots of the light guide panel has a bulge portion protruding to the lighting unit. At two sides of the bulge portion, each of the slots forms two slots walls with an obtuse angle, thereby expanding the transmitting angle for the multi-color lights from the lighting unit and enhancing the light-mixing uniformity while illuminating the keycap.

摘要： A keyswitch structure includes a casing, a first support, a second support, and a pressing stem. The casing forms an accommodating space and an opening communicating with the accommodating space. The first and second supports are disposed in the accommodating space and are directly and rotatably connected with the casing; the supports are also pivotally connected with each other. The pressing stem extends into the accommodating space to be rotatably connected with the first and second supports and protrudes from the casing through the opening. The pressing stem is movable parallel to a vertical direction relative to the casing through the first and second supports. A motion of the pressing stem in the vertical direction has a top dead center and a bottom dead center. When the pressing stem is at the top dead center and the bottom dead center, it does not touch the casing in the vertical direction.

The lighting board has a first reflective layer, a lighting circuit and two aligned micro-structure regions, all three at least partially being layered in parallel with each other. The two micro-structure regions reflect lights and are separated by the lighting circuit. The light emitting unit includes plural color dies connecting electrically with the lighting circuit. The light guide plate has a light guide hole for accommodating the light emitting unit. The color dies of the light emitting unit are aligned linearly, while the two micro-structure regions of the lighting board are aligned in perpendicular to the linearly-aligned color dies, with the micro-structure regions disposed at opposite sides the light emitting unit.
