Be connected to the keycap, the 4th connecting portion is pivotably connected to the base plate, and first linkage part and second linkage part can
Actively engage each other to make first support member produce with second support member when the keycap is pressed or the external force is released
It is raw to interlock, when the keycap is by the pressed by external force, second support member with the 4th connecting portion as the relative keycap of fulcrum and
The base plate is pivoted, and first support member slides with respect to the keycap and the base plate.
4. button according to claim 1, it is characterised in that：First support member has first connecting portion, the second connection
Portion and the first linkage part, second support member have the 3rd connecting portion, the 4th connecting portion and the second linkage part, first company
Socket part is slidably connected to the keycap, and the second connecting portion is slidably connected to the base plate, and the 3rd connecting portion is slidably
Be connected to the keycap, the 4th connecting portion is pivotably connected to the base plate, and first linkage part and second linkage part can
Actively engage each other to make first support member produce with second support member when the keycap is pressed or the external force is released
Raw to interlock, when the keycap is by the pressed by external force, second support member slides with respect to the keycap, and first support member is with respect to the key
Cap and the base plate slide.
5. the button according to claim 3 or 4, it is characterised in that：First linkage part is with second linkage part with axis hole
Coordinate or overlap the mode for abutting to engage each other.
6. the button according to claim 3 or 4, it is characterised in that：The base plate has connecting seat, and the connecting seat is to should
Axis hole is formed with the position of two connecting portions, and, to grooved hole being formed on the position of the 4th connecting portion, this second for the connecting seat
Connecting portion is slidably disposed in the slotted eye, and the 4th connecting portion is pivotably disposed in the axis hole.
7. button according to claim 1, it is characterised in that：First support member has first connecting portion, the second connection
Portion and the first linkage part, second support member have the 3rd connecting portion, the 4th connecting portion and the second linkage part, first company
Socket part is slidably connected to the keycap, and the second connecting portion is slidably connected to the base plate, and the 3rd connecting portion is slidably
Be connected to the keycap, the 4th connecting portion is slidably connected to the base plate, and first linkage part and second linkage part can
Engage each other up or down first support member is made when the keycap is pressed or the external force is released with second support
Part produces gearing, and when the keycap is by the pressed by external force, first support member slides with respect to the keycap and the base plate, and this second
Support member slides with respect to the keycap and the base plate.
8. button according to claim 1, it is characterised in that：The stop part is the projection being formed on the keycap, the bullet
Property part be formed at first support member to should be on the position of stop part elastomer block, the elastomer block interfered with projection and abuts.
