Abstract:
1. A magnetic contactor comprising: a frame configured to include a fixed contact which is connected to a power source and a load; a holder movably provided in the frame, and configured to include a movable contact and a fixed contact which are disposed to contact each other and to be separated from each other; a movable core coupled to one end of the holder, and configured to include a switch manipulating part; a bobbin configured to include a coil which is wound around an outer surface, wherein the bobbin generates a magnetic force when external power is applied to the coil; a fixed core coupled to the bobbin; an elastic member disposed between the holder and the bobbin, wherein the elastic member restores the movable core to an original position when the external power is cut off; an inverting switch provided within a moving range of the switch manipulating part, wherein an internal contact of the inverting switch is inverted when the inverting switch is contacted by switching manipulating part; an electronic circuit part configured to include a voltage dropping element, and receive an inversion signal from the inverting switch to control a current applied to the coil; and a normal position member configured to fix the switch manipulating part to a normal switch to induce a contact between the inverting switch and the switch manipulating part.
