The invention discloses a key structure by applying magnetic attraction force as a restoring force. A key cap support, a support of an actuating mechanism and another support in interaction with a magnetic attraction force are provided and arranged between a base and a key cap; when the key is free from being pressed by an external force, the two supports are driven by the magnetic attraction force to be stably supported on the base to form a stable support structure, so that the key cap is arranged at a position relatively far away from the base; when the key cap is pressed by the external force and moves towards the base, the magnetic attraction force is overcome by the external force, the two supports are separated, namely, the foregoing stable support structure is temporally damaged; and once the external force disappears, the two supports can form the stable support structure again due to the magnetic attraction force. Therefore, in the key structure, a traditional elastic member is prevented, a lifting mechanism still can acquire a relatively large arrangement space, and the structural strength and the actuating stability of the lifting structure are improved.
