The electromagnetically operated electromagnet includes a movable core coupled to a movable contact of the switching contact, a fixed core located in a peripheral portion of the movable core, and coils wound around the movable core and the fixed core. Currents are supplied to the coils to drive the movable core. Capacitors store charges for supplying the current to the coils. Resistors are arranged in series with a path through which the capacitors are connected with the coils of the electromagnetically operated electromagnet and through which a current for closing operation flows. Capacitances of the capacitors and values of the resistors are controlled to adjust a supplied current characteristic to the electromagnetically operated electromagnet.
