Moreover, the protruding portion 723 is preferably located within the projection range of the first end 760a on the keycap 720, and the first end 760a (the second magnetic member 750) abuts the protruding portion 723 and does not directly contact the first magnetic member 740. The magnetic attraction generated between the first magnetic member 740 and the second magnetic member 750 causes the first magnetic member 740 to maintain the second magnetic member 750 at a position against the keycap 720, thereby maintaining the keycap 720 in the unpressed position; In addition, the protrusion 723 avoids substantial contact between the first magnetic member 740 and the second magnetic member 750 and excessive magnetic attraction.

As shown in FIGS. 11A and 11B, when the keycap 720 receives the pressing force toward the bottom plate 710, the second magnetic member 750 moves away from the first magnetic member 740 with the keycap 720. When released by the pressing force, as shown in FIGS. 10A and 10B, the magnetic attraction between the first magnetic member 740 and the second magnetic member 750 drives the keycap 720 to move away from the bottom plate 710. Specifically, when the keycap 720 is pressed to move toward the bottom plate 710, the pressing force overcomes the magnetic attraction between the first magnetic member 740 and the second magnetic member 750, so that the keycap 720 is displaced relative to the bottom plate 710; The bracket 782 and the second bracket 784 are respectively rotated clockwise and counterclockwise toward the bottom plate 710 and close to each other, and the key cap 720 simultaneously generates downward displacement. On the other hand, the first pivoting portion 724 of the keycap 720 and the pressing against the movable panel 760 drive the movable panel 760 to rotate clockwise relative to the bottom plate 710 and the second pivoting portion 760b to rotate relative to the first pivoting portion 724; Board 760 One end 760a (ie, the second magnetic member 750) in turn rotates clockwise and away from the first magnetic member 740. In this embodiment, the body portion 761 of the movable plate 760 is rotated toward the bottom portion 710 to substantially abut the bottom portion 710, and the trigger portion of the movable plate 760 is rotated by the trigger portion 768 to trigger the switch layer 770. In addition, the first end 760a can extend into the opening 771 of the switch layer 770 such that the body portion 761 abuts against the bottom portion 710. When the pressing force is released, the magnetic attraction between the first magnetic member 740 and the second magnetic member 750 causes the second magnetic member 750 to move toward the first magnetic member 740, causing the movable plate 760 to rotate counterclockwise, thereby allowing the movable plate 760 to pass through. The second pivoting portion 764 is pushed up against the keycap 720. At this time, the first bracket 782 and the second bracket 784 are respectively rotated counterclockwise and clockwise toward the bottom plate 710 to open, and the keycap 720 is displaced upwardly away from the bottom plate. 710. Return to the position before pressing (as shown in FIGS. 10A and 10B).
