Abstract
A keyswitch structure includes a base plate, a key cap, a key base, a recovering member and a linkage mechanism having linkage members. The key base is disposed between the key cap and the base plate. The recovering member is disposed between the key cap and the base plate. The linkage members are physically separated from each other, and are respectively inclinedly disposed between the key base and the key cap, and collectively surround the recovering member. One end of each of the linkage members is pivotally connected to the key base, and the other end of each of the linkage members is slidably connected to the key cap.
Claims15
A keyswitch structure, comprising:
- a key cap having a plurality of peripheral edges, and any two neighboring ones of the peripheral edges form a corner;
- a base plate;
- a key base disposed between the key cap and the base plate;
- a recovering member disposed between the key cap and the base plate;
- and
- a linkage mechanism comprising a plurality of linkage members physically separated from each other, wherein the linkage members are inclinedly disposed between the key base and the key cap respectively, and collectively surround the recovering member, each of the linkage members is slidably connected to an area of the key cap neighboring to one of the peripheral edges of the key cap, and any two neighboring ones of the linkage members are connected to one of the corners of the key cap,
- wherein one end of each of the linkage members is pivotally connected to the key base, and the other end of each of the linkage members is slidably connected to the key cap for moving with the key cap.
