Fig. 4 and Fig. 6 are please referred to Fig. 9, Fig. 6 is that button of the embodiment of the present invention 1000 is in and is not pressed state and along figure
The diagrammatic cross-section of hatching B-B shown in 4, Fig. 7 are in for button of the embodiment of the present invention 1000 and are not pressed state and along Fig. 4 institutes
Show that the diagrammatic cross-section of hatching C-C, Fig. 8 are that button of the embodiment of the present invention 1000 is in pressing state and along section shown in Fig. 4
The diagrammatic cross-section of line B-B, Fig. 9 are that button of the embodiment of the present invention 1000 is in pressing state and along hatching C-C shown in Fig. 4
Diagrammatic cross-section.As shown in Fig. 4 and Fig. 6 to Fig. 9, when keycap 2 is in the position not being pressed as shown in Figures 6 and 7,
First adjutage 301 of the first support element 30 of 4 magnetic supporting mechanism 3 of magnetic attraction element, makes the first support element 30 be maintained at such as Fig. 6
With the position shown in Fig. 7 not being pressed, and since the first support element 30, the second support element 31 and third support element 32 are by the
Two adjutages, 310 third adjutage 320 is respectively coupled to the first adjutage 301, therefore the second support element 31 and third support element
32 are also limited by the first support element 30 and are maintained at the position not being pressed as shown in Figures 6 and 7, thereby either keycap 2
Main cap body 20 or the position not being pressed as shown in Figures 6 and 7 can be located at by extending cap body 21.
It is noted that in this embodiment, magnetic attraction element 4 corresponds to the first adjutage 301 of the first support element 30, because
In this embodiment, magnetic attraction element 4 limits the second support element 31 via the first support element 30 and is kept with third support element 32 for this
In the position not being pressed as shown in Figures 6 and 7, and magnetic attraction element 4 can be also set to corresponding second support element by the present invention
At 31 the second adjutage 310 or at the third adjutage 320 of corresponding third support element 32, i.e., the present invention can be according to practical need
It asks and magnetic attraction element 4 is set at corresponding first adjutage 301, correspond at the second adjutage 310 or correspond to third adjutage
At 320, make magnetic attraction element 4 can be used to magnetic the first adjutage 301, the second adjutage 310 and third adjutage 320 at least its
One of, and the mechanism interlocked each other with third support element 32 by the first support element 30 of supporting mechanism 3, the second support element 31
Design makes the main cap body 20 of keycap 2 be located at the position not being pressed as shown in Figures 6 and 7 with cap body 21 is extended.
Further, when keycap 2 is by a pressed by external force, keycap 2 is close towards bottom plate 1, and keycap 2 can drive support machine at this time
3 start of structure, and the first support element 30, the second support element 31 can interlock with third support element 32 and drive the main cap body 20 of keycap 2
With extension cap body 21.That is, the first support element 30, the second support element of the supporting mechanism 3 due to button 1000 of the present invention
31 design with the mechanism that third support element 32 interlocks each other so that no matter the position of user's pressing is the main cap for falling within keycap 2
At body 20 or extending at cap body 21, main cap body 20 can be kept same level height by supporting mechanism 3 with cap body 21 is extended, into
And keycap 2 is enable smoothly to be moved to toward bottom plate 1 such as Fig. 8 and pressing shown in Fig. 9 by Fig. 6 and non-pressing position shown in Fig. 7
Position keeps the trigger arm 6 for protruding from the first support element 30 close towards bottom plate 1 with the first support element 30 and triggers first circuit board 5
Switch 50.
Further, when being discharged after keycap 2 is by a pressed by external force, the first of 4 the first support element of magnetic 30 of magnetic attraction element
Adjutage 301 keeps the first adjutage 301 close toward magnetic attraction element 4, and thereby the first support element 30 can be by as shown in Fig. 8 and Fig. 9
Position be reset to position as shown in Figures 6 and 7, and due to the first support element 30, the second support element 31 and third support element
The 32 mechanism designs interlocked each other, the first support element 30 also drive the second support element 31 with third support element 32 by such as Fig. 8 simultaneously
It is reset to position as shown in Figures 6 and 7 with position shown in Fig. 9.During this, the first upper edge of the first support element 30
The first side 201 of the main cap body 20 of 302 pushing and pressing keycaps 2, the master of the second upper edge 311 pushing and pressing keycap 2 of the second support element 31
The second side 202 of cap body 20, and the third upper edge 321 of third support element 32 pushes against the extension cap body 21 of keycap 2, and then band
Dynamic keycap 2 keeps the trigger arm 6 for protruding from the first support element 30 separate towards bottom plate 1 with the first support element 30 smoothly far from bottom plate 1
And leave the switch 50 of first circuit board 5.In this embodiment, the first support element 30 of supporting mechanism 3, the second support element 31 with
Third support element 32 can be made of magnetic conductive material (such as metal) respectively, to be acted on by magnetic attraction element 4.In addition, bottom plate 1 is also
It can be made of magnetic conductive material (such as metal), but the present invention is not limited.
