FIELD: electrical engineering; applicable in switching devices. SUBSTANCE: magnetic circuit armature 3 is divided along the magnetic lines of force into parts mechanically coupled to one another by a flexible coupling, the running air-gap clearances between the poles of different parts of armature 3 and the pole of yoke 1 are different, and the contact system is divided into contact sets according to the number of parts of armature 3. Besides, the part of armature 3 with the maximum air-gap clearance under the pole is enveloped by winding 4 closed via a diode. EFFECT: enhanced speed of response and expanded functional capabilities. 1 dwg |
