Claim:
1. A switch structure adapted to an electronic device, wherein the electronic device has a casing, and the switch structure is disposed at an inner side of a key portion integrally formed in the casing, the switch structure comprising: an elastic member, connected to the key portion integrally formed in the casing; a force transmission member, disposed inside the key portion integrally formed in the casing; and a strain sensor, attached onto the elastic member, and the strain sensor and the force transmission member are located at two opposite sides of the elastic member respectively, wherein 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, and the strain sensor is deformed due to deformation of the elastic member such that a variation of resistance of the strain sensor occurs.
