A keyswitch includes a key cap, a base, a circuit board, a film, a resilient member and a pressure sensing member. The circuit board is disposed on the base. The film is disposed on the circuit board. The resilient member is disposed between the film and the key cap. The pressure sensing member is disposed at a position selected from a group consisting of a position between the resilient member and the film, a position between the film and the circuit board, and a position between the circuit board and the base. When the key cap is pressed by an external force, the pressure sensing member senses a magnitude of the external force.
