Abstract: The invention relates to an actuating element for setting the aim mark of a telescopic sight. According to the invention, the actuating element is rotatably located on the telescopic sight in the form of a rotary knob and the aim mark is displaced in a vertical and/or horizontal direction by means of a mechanical actuator, when the rotary knob is turned. In addition, the rotational area of the rotary knob is restricted in both rotational directions by at least one working region stop. The rotary knob is detachably coupled to the mechanical actuator. The working region stop(s) can be deactivated, allowing the rotary knob to be turned beyond the working region stop in both directions. The actuating element can be switched between at least three different modes. In mode A, the rotary knob is coupled to the mechanical actuator and the working region stop is inactive.

Abstract: The invention relates to an operating element for adjusting the cross-hairs of a telescopic sight. The operating element is in the form of a rotating knob, arranged to rotate on the telescopic sight, whereby a rotation of the rotating knob adjusts the cross-hairs by means of an adjuster mechanism. The rotating knob comprises one or several index marks, by means of which one or more positions of the cross-hairs may be indexed. The one or several index element(s) is/are arranged in one or several recess(es) and may be displaced therein in the circumferential direction of the rotating knob. The index elements are furthermore coupled to the rotating knob in the recesses such as to be rotated with the rotating knob on a rotation of the same.
