Abstract

The disclosure provides a key structure, including a bottom plate, a switch element, a keycap, a positioning element, and a linkage rod. The switch element is disposed on the bottom plate. The keycap is disposed on the switch element, and the switch element is located between the bottom plate and the keycap. The positioning element is connected to the bottom plate and located between the bottom plate and the keycap. The linkage rod is disposed between the keycap and the positioning element. The linkage rod has a portion disposed at a position corresponding to a groove, and two opposite sides of the linkage rod are each in contact with the keycap and the positioning element.
