Abstract
A key structure includes a bottom plate, at least one keycap, and a thin-film circuit board. The bottom plate has at least one elastic protruding portion. The keycap is liftably connected to the bottom plate and has a press portion and at least one trigger portion. The press portion is located at a central region of the keycap and faces the elastic protruding portion, and the trigger portion is located at a peripheral region of the keycap. When the key is lowered from a first position to a second position relatively to the bottom plate, the press portion downwardly presses the elastic protruding portion, and the press portion triggers an electrical trigger point of the thin-film circuit board. The keycap is adapted to be restored from the second position to the first position through an elastic force of the elastic protruding portion.
