Abstract
A key structure includes a base plate, a keycap, a membrane circuit board and an elastic plate. The keycap is located over the base plate. The keycap includes a top wall and a skirt part. The membrane circuit board is arranged between the keycap and the base plate. The membrane circuit board includes a pressure sensing structure. The elastic plate is arranged between the keycap and the membrane circuit board. The elastic plate includes a triggering part. The triggering part is extended toward the membrane circuit board and aligned with the pressure sensing structure. While the keycap is moved downwardly toward the elastic plate, the skirt part of the keycap is correspondingly moved to press the elastic plate. Consequently, the triggering part is moved downwardly to press the pressure sensing structure.
