Abstract:
1. An actuator for adjusting a lead mark of a telescopic sight, in which the actuator is in the form of a rotary knob mounted on the telescopic sight for rotation, which rotation of said rotary knob adjusts a position of the lead mark via an adjusting mechanism in a vertical and/or horizontal direction, and in which a turning range of said rotary knob is restricted by at least one operating range limit stop in both directions of rotation, wherein the rotary knob is releasably coupled to said adjusting mechanism; the at least one operating range limit stop can be deactivated such that the rotary knob can be turned in both directions beyond said at least one operating range limit stop; and the actuator can be switched between at least three different modes: a) in mode A the rotary knob is coupled to the adjusting mechanism and the at least one operating range limit stop is inactive, b) in mode B the rotary knob is decoupled from the adjusting mechanism and the at least one operating range limit stop is activated, and c) in mode C the rotary knob is coupled to the adjusting mechanism and the at least one operating range limit stop is activated.
