Exemplary embodiments are disclosed that include multi-voltage contactors, controls, and related methods.

A switching device including at least one pair of main fixed elongated conductor members arranged on a lower set wherein each of the main fixed elongated conductor members include a main fixed conductor end, wherein the main fixed conductor ends of the pair of main fixed elongated conductor members are separated from each other by a gap. A stationary intermediate set includes a fixed core and a coil, arranged above the lower set. An upper cover is arranged above the stationary intermediate set. A split movable carrier includes an upper portion, arranged above the fixed core and a lower portion arranged below the fixed core, which houses at least one main movable conductor bridge including main movable conductor ends. The upper portion of the split movable carrier houses a movable core and at least one auxiliary movable conductor bridge including auxiliary conductor ends and wherein the lower portion houses at least one main movable conductor bridge.

An electromagnet device includes an electromagnetic coil and a capacitor. The electromagnetic coil includes a first coil and a second coil connected in parallel to the first coil. The capacitor is connected to the second coil and configured to be charged by a voltage applied to the electromagnetic coil. Upon application of the voltage to the electromagnetic coil, the first coil and the second coil are turned from a non-conducting state to a conducting state. Upon completion of a charging of the capacitor by the application of the voltage to the electromagnetic coil, a current flow into the second coil will have ceased, and the second coil will have changed from the conducting state into the non-conducting state.

A contactor magnetic core includes a static magnetic core fixable to a magnetic plate of a contactor and having a main body insertable into a coil skeleton of the contactor, and a movable magnetic core insertable into the coil skeleton in a movable manner and having a flange at an upper end. When the static magnetic core and the movable magnetic core are inserted into the coil skeleton, the main body of the static magnetic core faces the flange of the movable magnetic core. A diameter of the main body of the static magnetic core is larger than a diameter of the flange of the movable magnetic core to increase an electromagnetic attraction between the static magnetic core and the movable magnetic core.

Electromagnetic relay includes drive coil, movable iron core that moves in first direction and second direction based on driving of drive coil, movable contactor that is disposed in first direction with respect to movable iron core and moves between first position and second position with the movement of movable iron core, fixed terminal that comes into contact with movable contactor at first position and does not into contact with movable contactor at second position, yoke that has second direction end surface portion positioned in second direction with respect to drive coil, and detection coil that detects movable iron core. Detection coil is disposed in second direction with respect to second direction end surface portion. Movable iron core moves in a coil of detection coil with the movement in first direction and second direction.
