    Tips: What is a mechanical interlock AC contactor?

    Mechanical interlock AC contactor is a combination of reversing contactor and mechanical interlock with a simple mechanical structure, which can save electric energy and eliminate power frequency noise. The device is a dynamic and static iron core, a pull-in coil, and a reaction spring. The pull-in coil is sleeved on the center column of the two iron cores. The iron core is in the shape of a mountain. The center column of the moving iron core is equipped with a rectangular lock column. The front plane of the lock column has a peach-shaped sliding groove. An elastic steel wire is installed on the opening plane of the center column of the static iron core, and the elastic steel wire slides in the required direction in the peach-shaped sliding groove of the lock column, which plays the role of self-locking when the load is energized and when the load is stopped.
