Abstract
A key structure includes a keycap, a base plate and a wing-type supporting element. When the keycap is depressed in response to an external force, a first frame and a second frame of the wing-type supporting element are pushed by each other through protrusion structures and rotating shafts. Consequently, the first frame and the second frame can be swung relative to the base plate.
