A keyswitch structure includes a keycap, a baseplate having a buffer space, a support movably disposed between the baseplate and the keycap, a magnetic member having a front section coupling the support, a middle section and a tail end, a magnetic unit disposed below the magnetic member, a switch film having a flexible portion extending over the buffer space. When the keycap is pressed, the support enables the magnetic member to move away from the magnetic unit, so the tail end is away from the flexible portion. When the keycap is released, a magnetic attraction force between the magnetic member and the magnetic unit enables the magnetic member to move toward the magnetic unit, so the tail end firstly contacts and pushes the flexible portion to deform toward the buffer space, and then the middle section contacts the magnetic unit to drive the support to support the keycap upward.

Keyswitch structure

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.

Magnetic keyswitch and related magnetic keyboard

A key structure including a baseplate, a key cap, a first lever, a second lever, a first magnetic member, a second magnetic member and a first buffer material is provided. The first magnetic member is disposed on the baseplate and located between the first lever and the second lever. The second magnetic member is disposed on the first lever and corresponding to the first magnetic member. The first magnetic member has a first portion. The second lever has a second central end. The first portion is adjacent to the second central end. When the key cap moves to a higher position, the first and second magnetic members move towards each other. The second magnetic member has a second portion and a third portion. The first buffer material is provided between the first and second portions and between the second central end and the third portion, respectively.

Key structure

A keyswitch structure includes a keycap having a lower surface and an engaging portion protruding from the lower surface, the keycap moving to a lower position when the keycap is pressed, a linking bar coupled with the engaging portion, a distal end of the engaging portion being lower than the linking bar when the keycap moves to the lower position, a baseplate disposed below the keycap, the baseplate having a recessed space corresponding to the engaging portion, and a buffer film disposed on the baseplate, the buffer film substantially extending over the recessed space and having a deformable portion corresponding to the recessed space, wherein when the keycap moves toward the baseplate to the lower position, the distal end of the engaging portion pushes the deformable portion to make the deformable portion extend into the recessed space.
