Armature magnetic system for electrical installation switch

摘要

The magnetic system has a magnetic yoke (10) enclosing a magnetic core (14) carrying a coil former (18) wound with an energising coil (19). The coil is electrically arranged in parallel with part of the yoke. Pref. the resistance of the magnetic coil and the magnetic yoke are selected so that the coil resistance is smaller than the resistance of the parallel part of the magnetic yoke. A terminal is pref. provided at one end of the coil and the yoke, the other end of the coil galvanically connected to the yoke.
