Abstract
The invention discloses a key and a keyboard comprising the same. The key comprises a base plate structure, a first magnetic member arranged on the base plate structure, a keycap, and a support device. The support device is arranged between the base plate structure and the keycap, and comprises a first support member and a second support member, which are movably connected to the keycap and the base plate structure. The first support member is equipped with a second magnetic member corresponding to the first magnetic member. A buffer structure is formed on the second magnetic member. The vertical distance between the base plate structure and the buffer structure is smaller than that between the second and first magnetic members. When the keycap is released, the magnetic attraction force between the second and first magnetic members drives the second and first magnetic members to move close to each other so as to make the keycap back to a position at which the keycap is not pressed. Before the second magnetic member contacts the first magnetic member, the buffer structure and the base plate structure interfere with each other to make one of the buffer structure and the base plate structure deform elastically so as to offer a buffer elastic force to the second magnetic member. The problem that the magnetic members collide with each other when the keycap goes back to the position at which the keycap is not pressed is solved, and the user experience is improved.
