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.

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.
