Abstract
A keyswitch includes a base, a first magnetic area, a key cap, a second magnetic area, a first linking bar and a second linking bar. The first magnetic area is disposed on the base. The second magnetic area is disposed on the key cap. A position of the second magnetic area is corresponding to a position of the first magnetic area. The first and second linking bars are disposed between the base and the key cap. The first and second linking bars are movably connected to the base and the key cap, so as to drive the key cap to move with respect to the base between a non-pressed position and a pressed position.
Claims22
A keyswitch comprising:
- a base;
- a first magnetic area disposed on the base;
- a key cap;
- a second magnetic area disposed on the key cap, a position of the second magnetic area being corresponding to a position of the first magnetic area;
- and
- a first linking bar and a second linking bar disposed between the base and the key cap, the first and second linking bars being movably connected to the base and the key cap, so as to drive the key cap to move with respect to the base between a non-pressed position and a pressed position;
- wherein when the keycap is not pressed, a magnetic attraction force between the first magnetic area and the second magnetic area keeps the key cap at the non-pressed position;
- when the key cap is pressed by an external force such that the second magnetic area moves away from the first magnetic area, the key cap moves with the first and second linking bars from the non-pressed position toward the pressed position;
- when the external force is removed, the second magnetic area moves toward the first magnetic area due to the magnetic attraction force such that the key cap moves with the first and second linking bars from the pressed position toward the non-pressed position.
A keyswitch comprising:
- a base;
- a first magnetic area disposed on the base;
- a key cap having a main body, a first extending arm and a second extending arm, the first and second extending arms being rotatably connected to the base and capable of rotating in an identical direction, so as to drive the key cap to move with respect to the base between a non-pressed position and a pressed position;
- and
- a second magnetic area disposed on the key cap, a position of the second magnetic area being corresponding to a position of the first magnetic area;
- and
- wherein when the keycap is not pressed, a magnetic attraction force between the first magnetic area and the second magnetic area keeps the key cap at the non-pressed position;
- when the key cap is pressed by an external force such that the second magnetic area moves away from the first magnetic area, the key cap moves with the first and second extending arms from the non-pressed position toward the pressed position;
- when the external force is removed, the second magnetic area moves toward the first magnetic area due to the magnetic attraction force such that the key cap moves with the first and second extending arms from the pressed position toward the non-pressed position.
