ELECTROMAGNETIC RELAY Russian patent published in 1997 - IPC

FIELD: electrical engineering; switching devices. SUBSTANCE: magnetic-core armature 3 is divided along magnetic lines of force into parts mechanically joined together through flexible link; working air gaps between different poles of armature 3 and pole of yoke 1 are different; contact system 5 is divided into contact groups according to number of parts of armature 3. Part of armature 3 having greater air gap above pole may be wound with short-circuited coil 4 which may be shorted out through diode. EFFECT: improved design. 5 cl, 2 dwg
