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.

Dependent claims

A magnetic keyswitch, comprising:

a base having at least one engaging structure and a hole;
a keycap;
a supporting device having a first support, an end of the first support being movably connected to the engaging structure and the other end of the first support being movably connected to the keycap, the first support having a magnet portion;
a magnetic component disposed on the base and functioned with the magnet portion to provide a recovering force to the keycap;
and
a metal thin sheet disposed under the base and having a bendable cantilever portion used to cover the hole, the magnetic component being removed through the hole while the cantilever portion is bent by an external force;
wherein an opening structure is formed on position of the metal thin sheet corresponding to the magnetic component, an end of the cantilever portion is connected to an inner wall of the opening structure, and the other end of the cantilever portion is connected to the other inner wall of the opening structure via a bridging portion.
