Key structure

A key structure, having a pressing area, the key structure comprising:

• a first membrane, having a first conductive layer and a first insulation layer that sequentially disposed on a surface of the first membrane, and the first insulation layer has a first opening in the pressing area, and a part of the first conductive layer is exposed from the first opening;
• a second membrane disposed opposite to the first membrane, the second membrane having a second conductive layer and a second insulation layer that sequentially disposed on a surface of the second membrane facing the first membrane, and the second insulation layer has a second opening corresponding to the first opening in the pressing area, and a part of the second conductive layer is exposed from the second opening to face the first conductive layer in the first opening;
• and
• a jumper, located in a shielding area and between the first insulation layer and the second insulation layer,
• wherein the first conductive layer in the shielding area has a first segment and a second segment, the first insulation layer has two third openings for exposing the first segment and the second segment, and the jumper is located on the first insulation layer and is in electrical contacts with the first segment and the second segment that exposed from the two third openings.
