Abstract: A key structure includes a switch circuit, an elastic member and a press unit. The switch circuit includes a predetermined press area. The elastic member is disposed on the predetermined press area of the switch circuit. The press unit is disposed on the elastic member and includes a flexible membrane and a plate. A part of the flexible membrane forms a press zone corresponding to the plate, wherein a position of the press zone is corresponding to a position of the elastic member, and the plate is fixed with the press zone. As one corner of the press zone is pressed, a corner of the plate moves downward accordingly while an opposite corner of the plate is limited by the flexible membrane from moving upward, such that the whole plate and the whole press zone move downward together to press the elastic member uniformly and trigger the switch circuit.
