Abstract
A switch structure and an electronic device using the same are provided. The electronic device has a casing, and the switch structure is disposed at an inner side of the key portion of the casing. The switch structure includes an elastic member, a force transmission member and a strain sensor. The elastic member is connected to the casing. The force transmission member is located inside the casing. The strain sensor is disposed on the elastic member, and the strain sensor and the force transmission member are disposed are two opposite sides of the elastic member respectively. The elastic member is configured to be deformed by the force transmission member when an external force is applied to an outside of the key portion.
