Abstract
A key structure includes a base and a linkage mechanism. The linkage mechanism includes a plurality of linking members movably connected to each other. The plurality of linking members includes at least two linking members rotatably positioned on the base, respectively. When a pressing force is applied to the linkage mechanism, the plurality of linking members move associated with each other to restrict a rotation range of the plurality of linking members with respect to the base.
