  • Patent number: 9202642
    Abstract: Disclosed is a magnetic contactor. A free space in which a DC converting circuit is provided is in a product can be secured by changing shapes of the movable core and the fixed core, and thus, in association with a low-capacity product, external AC power may be converted into DC power even without enlarging a size of a product. Also, a normal position member may be included in a movable core, and may induce the movable core to the original position, and thus, a mechanical mechanism relationship between the switch manipulating part included in the movable core and the other element is maintained.
