Summary:To provide an electromagnet device that can switch a voltage applied to an electromagnetic coil from an operating voltage to a holding voltage with a simple configuration.SOLUTION: A electromagnet device uses electromagnetic force to drive a contact device. The electromagnet device includes an electromagnetic coil and a capacitor. The electromagnetic coil includes a first coil and a second coil connected in parallel to the first coil. The capacitor is connected to the second coil and charged by applying a voltage to the electromagnetic coil. The first coil and the second coil change from a non-conducting state to a conducting state by applying a voltage to the electromagnetic coil. When the charging of the capacitor is completed by applying a voltage to the electromagnetic coil, the current flowing through the second coil is cut off, and the second coil changes from the conductive state to the non-conductive state.SELECTED DRAWING: Figure 5 【課題】電磁コイルに印加する電圧を動作電圧から保持電圧に簡単な構成で切り替えられる電磁石装置を提供することにある。【解決手段】電磁石装置は、電磁力によって接点装置を駆動させる。電磁石装置は、電磁コイルと、コンデンサとを含む。電磁コイルは、第１コイルと、第１コイルに並列に接続される第２コイルとを含む。コンデンサは、第２コイルに接続され、電磁コイルへの電圧の印加により充電される。第１コイル及び第２コイルは、電磁コイルへの電圧の印加により非導通状態から導通状態となる。第２コイルは、電磁コイルへの電圧の印加によりコンデンサの充電が完了することで、第２コイルに流れる電流が遮断されて導通状態から非導通状態となる。【選択図】図５
