PURPOSE: A solenoid-operated device and a solenoid-operated switching device for operating a switch by using electromagnetic force and a control device for controlling an electromagnet are provided to operate a switching device such as a circuit breaker by using the electromagnetic force. CONSTITUTION: An electromagnet(14) includes a movable magnet core, a stationary magnet core facing the movable magnet core, and a coil for coupling or decoupling the movable magnet core to or from the stationary magnet core according to electromagnetic force. A capacitor(16) is used for storing the power for exciting the coil. A control circuit board(18) is used for controlling a conductive direction from the capacitor to the coil in response to a close contact command or an open contact command for a switching device. A shaft(62) is connected to the movable magnet core in order to transmit driving force to the switching device through a link mechanism. The capacitor and the control circuit board are independently arranged around the electromagnet.
