| 发明名称 | Contact device | ||
| 摘要 | An electromagnet device is configured to generate a magnetic attractive force between a stationary core and a movable core when electricity is applied to a coil, so that the movable core is moved in a direction for coming into contact with the stationary core, and a movable shaft is moved in a direction in which a first end face of the movable shaft separates from a movable terminal. After the movable contact comes in contact with the fixed contact, the movable core moves further in a direction for coming into contact with the stationary core. A yoke made of a magnetic body is disposed between the movable terminal and the first end of the movable shaft. | ||
