A shaft door for an elevator has a door guard arrangement that includes a force sensor and a safety switch, wherein the force sensor comprises a contact unit and a spring mechanism with a spring. The force sensor senses a presence of an object clamped by the shaft door due to the shaft door closing wherein the contact element contacts the clamped object and transfers a force to the spring. The spring mechanism activates the safety switch to send a door-to-open command to a door operator of the elevator when the force transferred to the spring exceeds a stiffness of the spring.
