摘要： A keyboard includes a plurality of keyswitch structures and an adjusting plate movably disposed under the keyswitch structures. Each of the keyswitch structures includes a tactile feedback member. The adjusting plate includes a plate body and a plurality of adjusting bars protruding from the plate body toward the keyswitch structures and respectively corresponding to the tactile feedback members of the keyswitch structures. When the adjusting plate moves relative to the keyswitch structures, the adjusting bars drive the tactile feedback members to change tactile feedback of the keyswitch structures.

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.
