| 发明名称 | Electromagnetic relay | ||
| 摘要 | An electromagnetic relay includes a contact that includes a fixed contact and a movable contact, a permanent magnet provided on the peripheral side of the contact, and a non-magnetic body. The movable contact is displaceable in a first direction to move toward the fixed contact and in a second direction to move away from the fixed contact. The permanent magnet has a polarity direction perpendicular to the first and second directions. The non-magnetic body faces toward the direction of a Lorentz force that acts based on the permanent magnet in a direct electric current flowing through the contact. | ||

| 主权项 | 1. An electromagnetic relay, comprising: a contact that includes a fixed contact and a movable contact, wherein the movable contact is displaceable in a first direction to move toward the fixed contact and in a second direction to move away from the fixed contact; a permanent magnet provided on a peripheral side of the contact, wherein the permanent magnet has a polarity direction perpendicular to the first and second directions; and a non-magnetic metal body that faces toward a direction of a Lorentz force that acts on a direct electric current flowing through the contact based on the permanent magnet. | ||
