Abstract: A key structure is provided. The key structure includes a base plate, a key cap and a lifting mechanism is provided. The base plate includes a first bottom wall. The key cap is disposed opposite to the base plate and includes a first cap wall. The lifting mechanism is movably connected between the key cap and the base plate, so that the key cap could reciprocate with respect to the base plate. The lifting mechanism includes a first lower shaft portion and a first upper shaft portion, which are respectively movably connected on the same side of the key cap and the base plate. When the key cap is in a released state, the first upper shaft portion presses against the first cap wall, but the first lower shaft portion is separated from the bottom wall by a maintaining gap.

Abstract: A keyswitch support connection structure incudes a bottom plate portion, a cantilever plate, and a joining portion. The cantilever plate extends upward from a joining hole of the bottom plate portion and has a holding structure. The joining portion and the joining hole are firmly engaged with each other. The joining portion encapsulates the holding structure. The joining portion and the bottom plate portion jointly form or the joining portion alone forms a support connection portion. A keyswitch structure includes a base, a keycap above the base, and first and second keyswitch supports connected to and between the keycap and the base. The base includes the above keyswitch support connection structure. The first keyswitch support is rotatably connected to the support connection portion.

Abstract: A keyswitch support connection structure is a combined structure which includes a structural plate and a joining portion. The joining portion and the structural plate are firmly engaged with each other through a joining structure of the structural plate. The joining structure includes at least one of a protruding portion, a through hole, a side hole, a joining hole, a cantilever plate, and a protruding bridge portion. The joining portion includes at least one hook arm, configured to forma support connection portion. A keyswitch structure includes a base, a keycap above the base, two keyswitch supports connected to and between the base and the keycap, and the keyswitch support connection structure structurally integrated into the base or the keycap. The keycap is vertically movable relative to the base through the two keyswitch supports. One of the two keyswitch supports is connected to the support connection portion.

Abstract: A keyswitch structure includes a base plate, a keycap, a scissors support connecting the keycap and the base plate, a linking support rotatably disposed on the base plate, a movable part movably disposed relative to the base plate, and a magnetic part on the movable part. The linking support includes a magnetic portion and a driving portion. The magnetic part and the magnetic portion produce a magnetic attraction force therebetween. When the movable part is located at a first position, the magnetic part is located under the magnetic portion, and the magnetic attraction force drives the keycap through the linking support to move away relative to the base plate. When the movable part moves from the first position to a second position, the magnetic part moves away relative to the magnetic portion, so that the magnetic attraction force decreases so as to make the keycap move toward the base plate.

Abstract: A magnetic keyboard has a plurality of magnetic keyswitches, and each magnetic keyswitch include a base, a keycap, a supporting device, a magnetic component and a metal thin sheet. The base has at least one engaging structure and a hole. The supporting device has a first support, an end of the first support is movably connected to the engaging structure, and the other end of the first support is movably connected to the keycap. The first support has a magnet portion. The magnetic component is disposed on the base and functioned with the magnet portion to provide a recovering force to the keycap. The metal thin sheet is disposed under the base and has a bendable cantilever portion covering the hole. While the cantilever portion is bent by an external force, the magnetic component can be removed through the hole.

Abstract: A keyswitch includes a base plate, a keycap, a balance bar, at least one buffer layer, and a membrane switch layer disposed on a base plate. A linking portion of the base plate protruding upward penetrates through the membrane switch layer such that a contact portion of the membrane switch layer is located proximate to the linking portion. A connecting section of the balance bar passes through a through hole of the linking portion. The at least one buffer layer is formed on a lower surface of the contact portion, and extends along a first lateral path and a second lateral path. The contact portion supports the connecting section to abut against a top wall of the linking portion. When the keycap moves upward and downwards, the connecting section pivotally slides on the contact portion, between the first lateral path and the second lateral path.

Abstract: A keyswitch includes a board, a cap, a lifting mechanism, a returning device, first and second blocks. The lifting mechanism is disposed between the board and the cap and includes first and second plates pivoted to the board and opposite to each other. The returning device is located between the first and second plates and includes first and second magnetic members. The first magnetic member extends from the first plate corresponding to the second magnetic member disposed on the board. An abutting part extends from the second plate and abuts under the first magnetic member. The first and second blocks are formed on the cap and respectively spaced from the first and second plates. When the first and second plates are pressed to deform, the first and second blocks abut against the first and second plates respectively to keep the abutting part located under the first magnetic member.
