ELECTRIC SWITCHING DEVICE WITH ELECTROMAGNETIC DRIVE Russian patent published in 2021 - IPC H01H33/66 H01H50/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to electromechanical switching devices, it can be used in the design of circuit breakers, contactors, polarized relays, remote switches and other electrical switching devices. A switching electrical device with an electromagnetic drive in the form of a fixed magnetic circuit with coils and an armature installed in the plastic device case, made in the form of a plate fixed on a plastic traverse of the device perpendicular to the axis of the armature, which is spring-loaded by return springs to the device case, contains an armature of an electromagnetic drive. The armature is immersed in a niche made in a plastic traverse, and attached to it to form a gap between the planes of the armature and the traverse niche facing each other by means of a ball joint, which is a ball head with a finger mounted on an axis passing through the central hole in the traverse. The finger of the ball joint is rigidly installed in the hole of the armature, the axis of which is perpendicular to the axis of the hole in the traverse, and the through hole of the ball head. The niche in the traverse is made with the possibility of partial immersion of the armature in it for limited movement rotationally and oscillatory inside the niche around the center of gravity of the armature relatively to the plane of the surface of the traverse.

EFFECT: technical result of the claimed invention is an increase in reliability by increasing the vibration shock resistance by increasing the stability of the force of holding the armature of the electromagnet in the final position by its self-adjustment.
