Abstract:
A drive solenoid, a yoke, an armature and at least one contact are mounted in a housing of an electromagnetic switching device. The drive solenoid, yoke and armature are inductively intercoupled, in such a way that when an inrush current is applied to the drive solenoid, the armature can be displaced into a pickup position, thus directly or indirectly actuating the contact. The yoke and/or armature contain(s) pulverulent magnetic material.
