Arrangement for emergency manual operation of switching magnets whose armature is movable in a pole tube to one end position by spring force and against spring force to a second end position by magnetic field stimulation

摘要

the arrangement has an axially movable pulling element in the pole core which can be moved by a manual actuator and a drive element which works in conjunction with the armature (3) to move it to the second end position. The armature, pole core (7), spring arrangement (5), pulling element (31) and actuator (23) are combined to form a prefabricated unit which can be inserted into the pole tube (1) from the inner open end and connected to it
