<p>PROBLEM TO BE SOLVED: To provide a magnetic contactor capable of achieving an operation of a b-contact switch using a switch manipulation member included in a movable core without an increase in size of a product.SOLUTION: A magnetic contactor includes: a frame configured to include a fixed contact; a holder movably provided at the inside of the frame and configured to include a movable contact which can be brought into contact with or separated from the fixed contact; a movable core coupled to the holder to interoperate with the holder; a bobbin provided inside the frame in a fixed manner and configured to include a coil; a fixed core coupled to a side surface of the bobbin and configured to absorb the movable core with a magnetic force; an elastic member provided between the holder and the bobbin; a b-contact switch configured to sense a closing completion time of the movable contact by using a mechanical mechanism relationship with the movable core; an electronic circuit part configured to limit a current applied to the coil by a sensing signal input from the b-contact switch; and a switch manipulation member provided at one end of the movable core and configured to operate the b-contact switch.</p> |
