At this time, the elastic member 30 restores and maintains the movable member 40 in place after the movable member 40 is pushed upward.
For another example, when the movable part 40 is pressed down, the triggering module sends a triggering signal to the control unit, and the control unit receives the triggering signal and sends a repulsive force signal to the current driving circuit, so that the current driving circuit reversely energizes the connected electromagnetic part 20, thereby changing the acting direction of the magnetic field between the magnet part 10 and the electromagnetic part 20 to generate the repulsive force. At this time, the magnet member 10 generates a pushing force to the movable member by the repulsive force of the electromagnetic member 20 through the key cap 420, and after the pushing force is continued for a short time, the control unit transmits a magnetic attraction force signal to the current driving circuit, thereby changing the magnetic field acting direction between the magnet member 10 and the electromagnetic member 20 to generate the magnetic attraction force. At this time, the magnet assembly 10 generates a pulling force to the movable assembly 40 by the stopper 430 under the magnetic attraction of the electromagnetic assembly 20, so that the movable assembly 40 moves downward in the vertical direction.
