Abstract: A luminous touch keyboard includes a baseplate, a plurality of keycaps, a plurality of support mechanisms connected between the baseplate and the keycaps, and a keyboard composite electrode module disposed between the baseplate and the keycaps and configured to sense a non-pressing movement over the keycaps and to provide light emitting through the keycaps. The support mechanism supports the keycap to move relative to the baseplate and the keyboard composite electrode module. The keyboard composite electrode module includes a light source circuit and a plurality of electrode matrices arranged along a first direction and a second direction. Two of the electrode matrices adjacent in the second direction are mis-aligned. The light source circuit includes a plurality of light sources disposed in the plurality of electrode matrices in a one-to-one manner, and the position of the light source in the electrode matrix is correspondingly the same.

Abstract: A luminous keyboard and an optical module thereof are provided. The optical module includes a light guide sheet, a reflective film on one side of the light guide sheet, and an optical film on another side of the light guide sheet opposite to the reflective film. The optical film has a mask pattern. The mask pattern defines a light-transparent region, a light-shielding region, and a light modulation region extending from the light-shielding region to the light-transparent region. The light-transparent region allows light to pass therethrough. The light-shielding region blocks light. The light modulation region partially allows light to pass therethrough and partially blocks light, so that an average light-transmitting rate per unit area of the light modulation region is smaller than that of the light-transparent region and larger than that of the light-shielding region.

Abstract: A keyswitch includes a bottom board, a cap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the cap structure and the bottom board to make the cap structure movable upward and downward relative to the bottom board. The elastic member is connected to the cap structure so as to be detached from the lifting mechanism together with the cap structure when the cap structure is separate from the lifting mechanism.

Abstract: 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.

Abstract: A keyswitch includes a base, a keycap, a lift mechanism, a touch circuitry portion, and an outer covering layer. The keycap is connected to the base through the lift mechanism so as to move up and down relative to the base. The touch circuitry portion is disposed on the top surface of the keycap. A connection circuitry portion extends from the touch circuitry portion. The outer covering layer covers the touch circuitry portion and at least a portion of the connection circuitry portion. Thereby, the keyswitch can provide touch function without excessively increasing the whole thickness of the keyswitch. A keyboard includes a plurality of the keyswitches and therefore can provide touch function without excessively increasing the whole thickness of the keyboard.

Abstract: A restoration assembly of a button switch includes first and second sleeves, and a spring disposed between the two sleeves. A first outer diameter of the first sleeve is less than a second inner diameter of the second sleeve to make the second sleeve movably jacket outside the first sleeve. The jacketed first and second sleeves are disposed between a key cap and a base of the button switch. The spring has a first end portion, a second end portion and a middle section. A middle outer diameter of the middle section of the spring is larger than a first inner diameter of the first sleeve. During the spring being compressed along with the key cap being pressed downward, the middle section is squeezed to shrink and slide into the first sleeve through an end edge of the first sleeve, thereby producing a tactile feedback and/or a first sound.

Abstract: A keyboard touch electrode module includes a plurality of same electrode matrices, which are arranged along a lengthwise direction and a widthwise direction and formed by a plurality of series of first electrodes and a plurality of series of second electrodes which interlace with each other. Adjacent two of the electrode matrices in the widthwise direction are mis-aligned. The electrode matrices thereon define a plurality of key projection areas, each of which covers a same key-face electrode pattern. A touch keyboard includes a base, a plurality of keycaps, a plurality of supporting structures connected to and between the base and the keycaps, and the keyboard touch electrode module disposed between the base and the keycaps. The keyboard touch electrode module can senses a non-pressing movement on the keycaps. The keycap can move up and down relative to the base and the keyboard touch electrode module through the corresponding supporting structure.

Abstract: A keyswitch device includes a cap, a board, a first returning member, and a second returning member. The board is disposed opposite to the cap. The first returning member is disposed between the cap and the board and includes a magnet member and a magnetic member for providing a magnetic force. The second returning member is disposed between the cap and the board for providing an elastic force. When the cap is released at a lowest position, the cap moves upward via the elastic member and then arrives and stays at a highest position via the magnetic force.

Abstract: A battery assembly includes a battery holding unit and a battery unit removably held by the battery holding unit. The battery unit includes a battery, a first engaging portion, and a second engaging portion. The battery holding unit includes a holding member selectively engaged with the first engaging portion or the second engaging portion to hold the battery unit at a first position or a second position. When the holding member and the first engaging portion relatively move away from each other along a disengagement direction, the battery unit moves along a detachment direction from the first position to the second position at which the holding member engages with the second engaging portion, and the second engaging portion is allowed to move to disengage from the holding member, so that the battery unit moves again along the detachment direction to be removed from the battery holding unit.
