摘要： 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.

摘要： 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.

摘要： An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.

摘要： A keyswitch structure includes a base having a positioning means, an cover combined with the base, a plunger with an cam portion movably coupling with the cover relative to the base, a restoring unit disposed between the base and the plunger to provide a restoring force to enable the plunger to move along a direction away from the base, a tactile feedback member having a positioning portion positioned by the positioning means and an extending arm extending across a moving path of the cam portion, and an adjusting unit being movable to drive the positioning portion to shift, so that the tactile feedback member has a first deformation or a second deformation, and a pressing force required for the cam portion to pass the extending arm when the plunger moves toward the base is changed.

摘要： An optical keyswitch includes a casing having a movable portion, a shaft movably disposed on the casing, a resilient member accommodated in the casing, and a switch module including a circuit board, an emitter, and a receiver. The emitter emits an optical signal along an optical path to the receiver. When the shaft is at a non-pressed position, the movable portion has a first spatial relation with the optical path, and the receiver receives the optical signal of a first intensity. When the shaft moves, in response to a pressing force, to a pressed position, the shaft compresses the resilient member and pushes the movable portion to move, so the movable portion no longer has the first spatial relation with the optical path, the optical signal received by the receiver has a second intensity different from the first intensity, and the switch module is triggered to generate a triggering signal.
