Abstract
A key structure including a keycap, a base plate, at least one bracket and a circuit board is provided. The base plate is arranged opposite to the keycap and includes at least one through hole located under the keycap. The bracket is rotatably connected between the keycap and the base plate, keeps flat when the keycap is lowered to a lowest position, stands obliquely when the keycap is raised, and includes at least one abutting portion and a lower protrusion. The circuit board is located between the keycap and the base plate and has at least one opening and at least one extension portion. When the keycap reaches the lowest position, the extension portion of the circuit board at least partly overlaps with the abutting portion of the bracket, and the lower protrusion of the bracket at least partly enters at least one opening of the circuit board.
