Abstract
A key structure comprises a bottom board, a key cap and two first balance plates. The two first balance plates are plate shaped, disposed between the bottom board and the key cap, and symmetric to each other. An upper end of each of the two first balance plates is connected to the key cap. A lower end of each of the two first balance plates is connected to the bottom board. Thereby, a key structure is formed which provides a normal tactile feel while saving space, thereby achieving a slim design.
