The movable iron core is connected to the moving member and is configured to move by a magnetic force generated by the coil. The moving member is made of resin having electrical insulation. The moving member includes a first member and a second member. The second member is connected to the first member by snap fitting. The first member includes a first protrusion. The second member includes a second main body, a first locking portion, and a first arm. The first locking portion locks to the first protrusion. The first arm connects the second main body and the first locking portion. A thickness of the first arm is smaller than a thickness of the first locking portion.

According to an electromagnetic switch of the present invention, a crossbar operating in conjunction with a movable core slides in response to magnetization or demagnetization of an operating coil to cause attraction or separation between a fixed contact point and a movable contact point on the supply-side and between a fixed contact point and a movable contact point on the load-side. The electromagnetic switch further includes a first crossbar sliding part and a second crossbar sliding part, as well as a first casing sliding part and a second casing sliding part that allow the first and second crossbar sliding parts to slide. A contact between the first casing sliding part and the first crossbar sliding part or between the second casing sliding part and the second crossbar sliding part causes the crossbar on the side of the movable core to be tilted in a direction opposite to the direction of gravity with respect to the horizontal.

An electromagnetic repulsion actuator for a circuit breaker is provided. The actuator can include a housing; a first fixed electrode having therein an operating space open at both sides; a pair of movable electrodes capable of reciprocally moving and being electrically connected to the first fixed electrode; second fixed electrodes selectively contacting the pair of movable electrodes to be electrically connected thereto, thereby transferring power supplied from a first side to a second side; and actuating coils selectively moving the movable electrodes in a direction of being separated from the second fixed electrodes by generating electromagnetic force from induced current. In the present invention as above, the structure of a circuit breaker is simplified and moving speeds of the movable electrodes are increased since the movable electrodes move by using induced current generated by a close coil and open coils to perform an open operation.
