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 assembly includes a base, a pressable plate, a first magnetic acting member and a second magnetic acting member. An accommodating space is defined within the base, and an upper surface of the base is provided with a connecting portion. The pressable plate includes a pressing portion, an acting portion and a pivotal connection portion located between the pressing portion and the acting portion and pivotally connected to the connecting portion. The first magnetic acting member is disposed on the acting portion; the second magnetic acting member is disposed on the base corresponding to the first magnetic acting member. The keyswitch assembly is configured such that the first magnetic acting member and the second magnetic acting are attracted or repulsed each other by a magnetic force, so as to provide or change a pressing resistance of the pressing portion.
