FIELD: electricity.
SUBSTANCE: electromagnetic drive of switch device contains magnetic conductor with reel, located on its central plunger, basic armature and trip-free release armature. Magnetic conductor is implemented as built-up with L-shaped elements, where some of flank outsides are joint and forming magnetic conductor central plunger, and others of flank outsides are located in a one plane. Basic armature and trip-free release armature are also implemented as L-shaped elements, forming closed detachable circuits with L-shaped elements of magnetic conductor.
EFFECT: processability increasing and reducing of electric steel consumption.
