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.
