FIELD: electrical engineering; electromagnets whose armature is mechanically latched when their winding is de-energized.

SUBSTANCE: proposed electromagnet is characterized in that its armature is coupled with rod incorporating flat spring terminating in cylindrical stop whose length is greater than spring width. Cylindrical stop is initially in bottom part of angle member and rests on its horizontal part while horizontal part of angle member abuts against stop due to force applied by disconnecting spring that transfers its pressure through flat spring and due to force of reversing spring. Vertical part of angle member has tooth on its top that transfers to depression. Center of the latter is disposed on core axis. Angle member mounts pins disposed on its side surfaces; these pins enter holes on support that also functions as angle member stop in working position of electromagnet. Support is mounted on electromagnet flange joined with stop. Cavity is provided between angle member walls for flat spring displacement. Armature has guides preventing its turning about its axis. Electromagnet is supplied with pulse-controlled power and its armature is latched in working position upon termination of control pulse.
