(57) ABSTRACT A displacement sensor for sensing the displacement of a movable component of a device is provided. A flexible ele ment of the displacement sensor includes a mounting portion mounted to the device and a coupling portion spaced apart from the mounting portion. A displacement conversion mechanism is coupled to the movable component and is fur ther coupled to the coupling portion of the flexible element. The displacement conversion mechanism is configured to convert a larger displacement of the movable component into a smaller displacement of the coupling portion of the flexible element. The flexible element is arranged such that a displace ment at the coupling portion causes the flexible element to bend.
