Abstract:
A method is disclosed for producing a pole face of a metal closing elements of a solenoid, especially for electromechanical switchgear. In at least one embodiment, the method includes machining the surface of a crude stamped part of the closing element to give the pole face. A corresponding armature, yoke, solenoid and switchgear are also disclosed.
