Title: Device for emergency hand operation with switching magnets

Abstract: A device for emergency hand operation has switching magnets with an armature that can be moved in the pole pipe to a final position by the force of a spring assembly, and can be moved against the spring force to a second final position by a magnetic field excitation. The device has a tensional member which can be axially displaced and moved by a manual actuating device. A carrier interacts with the armature to move the carrier against the spring force and to the second final position. The armature, the pole core, the spring assembly, the tensional member and the actuating device are combined to form a prefabricated component which can be inserted into the pole pipe via its inner open end and which can be connected to the pole pipe.
