The invention relates to a device for limiting a movement of a member driven by a motor, comprising at least two switches connected to a circuit of the motor and movable actuating elements driven by the motor and co-acting with the switches, which actuating elements are movable substantially independently of each other. A normal end switch and an emergency end switch can hereby be actuated without the danger of unintentional actuation of the emergency switch. The actuating elements can be movable by a joint drive element connected to the motor and can be resiliently deformable. The actuating elements can form part of a single resiliently deformable actuating member and have a different thickness, and thereby a differing stiffness. The actuating member can herein be a leaf spring, which has an incision from an outer end which mutually separates the actuating elements.
