FIELD: electrical engineering.
SUBSTANCE: electromagnetic actuator contains a movable part configured to form the magnetic core of the actuator and move relative to the fixed body between the retracted position and the deployed position. The movable part has a circular cross section and one or more recesses. One or more recesses are located on either of the two sides relative to the plane of symmetry of the moving part, aligned perpendicular to this plane and have a constant width. The electromagnetic actuator also includes a permanent magnet forming part configured to generate a first magnetic force holding the movable part in a retracted position. It also contains a coil configured to induce a second magnetic force opposite to the first magnetic force when the coil is supplied with an excitation electric current.
EFFECT: increasing the reliability of operation and reducing the weight and size of the actuator in the switching device.
