In this embodiment, the supporting unit 380 includes a first bracket 382 and a second bracket 384, wherein each of the first bracket 382 and the second bracket 384 is rotatably connected to the keycap 320 and the bottom plate 310, so that the keycap 320 is relative to the bottom plate 310 When moving, the keycap 320 produces a vertical displacement and a horizontal displacement relative to the base plate 310 at the same time. For example, the first bracket 382 and the second bracket 384 can respectively be frame-type connecting rod structures, wherein the first bracket 382 and the second bracket 384 preferably have the same structure to reduce manufacturing costs, but this is not a limitation limit. Moreover, the first bracket 382 and the second bracket 384 respectively have mechanisms for coupling with the keycap 320 and the bottom plate 310 on two opposite sides. The first bracket 382 has a first shaft portion 382a and a second shaft portion 382b on opposite sides. The first shaft portion 382a is rotatably engaged with the first shaft hole 325 of the keycap 320, and the second shaft portion 382b is rotatable.

As shown in FIG. 9A , when the pressing force is released, the magnetic attraction force between the first magnetic member 440 and the second magnetic member 450 drives the keycap 420 to move away from the bottom plate 410 . Specifically, when the keycap 420 is pressed, the pressing force overcomes the magnetic attraction force between the first magnetic part 440 and the second magnetic part 450, so that the keycap 420 is connected to the first magnetic part 415 through the second joint part 415 in the form of a guide rod. The movement guide in the guide groove of the coupling part 425 moves downward and drives the second magnetic part 450 away from the first magnetic part 440 . As shown in FIG. 9B , when the keycap 220 is pressed, the second joint part 415 moves relative to the first joint part 425; when the pressing force is released, the magnetic attraction force between the first magnetic part 440 and the second magnetic part 450 Make the second magnetic part 450 move towards the first magnetic part 440, and then drive the keycap 420 to move up and return to the position before pressing through the first joint part 425 guided along the second joint part 415 (as shown in FIG. 9A ).

When the keycap 520 moves relative to the bottom plate 510 , the third coupling portion 528 moves relative to the fourth coupling portion 588 so that the keycap 520 produces a vertical displacement and a horizontal displacement relative to the bottom plate 510 at the same time. Specifically, the third coupling portion 528 has a first slope 528a, and the fourth coupling portion 588 has a second slope 588a. When the keycap 520 moves relative to the bottom plate 510, the first slope 528a relatively moves along the second slope 588a. On the other hand, the first joint part 525 is movably connected to the second joint part 515 and serves as a position-limiting structure. For example, the first combining portion 525 and the second combining portion 515 can be connected in a way that the hook-shaped portion engages with the cross bar.

Thereby, the magnetic attraction generated between the first magnetic member 540 and the second magnetic member 550 makes the first magnetic member 540 and the second magnetic member 550 substantially directly contact each other, thereby maintaining the keycap 520 at the unpressed position. On the other hand, the first joint portion 525 is engaged with the second joint portion 515 , for example, to maintain the height of the keycap 520 from the bottom plate 510 .

Moreover, when the pressing force is released, as shown in FIG. 11B , the magnetic attraction force between the first magnetic member 540 and the second magnetic member 550 drives the keycap 520 to move away from the bottom plate 510 . Specifically, when the keycap 520 is pressed and moves toward the bottom plate 510, the first inclined surface 528a of the third coupling portion 528 moves toward the bottom plate 510 along the second inclined surface 588a of the fourth coupling portion 588 so that the keycap 520 moves to the left simultaneously. and rightward displacement, that is, vertical displacement and horizontal displacement are produced simultaneously. At this time, the bottom 521 of the keycap 520 is pressed against the first end 561 (ie, the first horizontal extension 561a) of the movable plate 560, and drives the movable plate 560 relative to The second end 562 of the bottom plate 510 (ie, the second horizontal extension 562 a or the second magnetic member 550 ) is also rotated counterclockwise to move away from the first magnetic member 540 to actuate the button structure. When the pressing force is released, the magnetic attraction between the first magnetic part 540 and the second magnetic part 550 makes the second magnetic part 550 move toward the first magnetic part 540, so that the first end 561 of the movable plate 560 (that is, the first The horizontal extension portion 561a) pushes upward against the bottom 521 of the keycap 520 and is guided by the first inclined surface 528a and the second inclined surface 588a to drive the keycap 520 to produce an upward and rightward displacement away from the bottom plate 510 and return to the position before pressing (as shown in Figure 11A).
