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.
