Abstract: A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.

Abstract: 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.

Abstract: 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.

Abstract: A magnetic type keyswitch includes an actuating member and a switch unit. The actuating member is movable in response to a pressing force. The switch unit includes a circuit board, a Hall sensor electrically connected to the circuit board, and a magnet spaced apart from the Hall sensor by a fixed distance. When the pressing force is not applied, the magnet enables the Hall sensor to output a first voltage, and when the pressing force is applied, the actuating member moves relative to the magnet and the Hall sensor in response to the pressing force, so that the Hall sensor outputs a second voltage different from the first voltage, and the magnetic type keyswitch generates a triggering signal.

Abstract: An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

Abstract: A tactile-adjustable keyboard includes plural keyswitches, an adjustment frame and a hybrid operation button. The adjustment frame is disposed corresponding to the keyswitches to move and interfere at least one of the keyswitches. The hybrid operation button includes a tactile switch, a non-tactile knob disposed at least partially surrounding the tactile switch, and a lens disposed at least partially surrounding the non-tactile knob. The tactile switch includes a switch shaft and a switch bar. The switch shaft is disposed in rotatable connection with the adjustment frame to move the adjustment frame. The switch bar extends externally from the switch shaft. A tactile feedback of said one keyswitch changes in response to the rotation of the tactile switch, while a non-tactile signal is generated in response to the rotation of the non-tactile knob, and the lens is illuminated in response to the rotation of the tactile switch.

Abstract: A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.

Abstract: A keyboard includes a cover plate having a plurality of first keyholes, an adjustment mechanism disposed under the cover plate, and a plurality of keyswitches. The adjustment mechanism includes an adjustment frame and a plurality of adjustment portions. The adjustment frame includes a plurality of ribs defining a plurality of second keyholes corresponding to the plurality of first keyholes, respectively. Each of the adjustment portions is proximate to a corresponding one of the second keyholes. Each of the keyswitches includes a tactile feedback member and is located in corresponding first and second keyholes, so that the adjustment portion corresponds to the tactile feedback member of its corresponding keyswitch. The adjustment frame is movable relative to the cover plate, so that each of the adjustment portions drives a portion of the tactile feedback member to move, to change tactile feedback of the keyswitches.
