Abstract
A key structure including a base, a light sensing module, a carrier, a magnetic member, a cap, and a scissor structure are provided. The light sensing module is disposed at the base. The carrier is located above the base. The magnetic member is disposed on the carrier. The cap is adapted to be assembled to the carrier via a magnetic attracting force of the magnetic member or adapted to be detached from the carrier via overcoming the magnetic attracting force of the magnetic member. The scissor structure is connected between the base and the carrier. The carrier and the cap disposed thereon move up and down relative to the base via the scissor structure. An orthogonal projection of the magnetic member on the base is not overlapped with an orthogonal projection of the light sensing module on the base. A keyboard is also provided.
