Zusammenfassung: | To suppress a force in a direction separating a movable terminal from a fixed terminal while suppressing the enlargement of a device and the deterioration of a fixed contact and a movable contact.SOLUTION: An electromagnetic relay includes first and second fixed terminals each having a fixed contact and arranged side by side with a space therebetween, a movable terminal having two movable contacts that contact and separate from the fixed contacts of the first and second fixed terminals, and a driving portion that drives the movable terminal, and further includes yokes that are attached to the first and second fixed terminals, and pass a part of a magnetic flux that causes a force in a direction for separating the movable terminal from the two fixed terminals due to a current that flows in the order of the first fixed terminal, the movable terminal, and the second fixed terminal.SELECTED DRAWING: Figure 1
【課題】装置の大型化を抑制すると共に固定接点および可動接点の劣化を抑制しつつ、可動端子を固定端子から離間させる方向の力を抑制する。【解決手段】それぞれ固定接点を有すると共に互いに間隔をおいて並んで配置される第1、第2固定端子と、第1、第2固定端子の固定接点に接離する2つの可動接点を有する可動端子と、可動端子を駆動する駆動部とを備える電磁リレーにおいて、第1、第2固定端子に取り付けられ、第1固定端子、可動端子、第2固定端子の順に流れる電流に起因して可動端子を2つの固定端子から離間させる方向の力を生じさせる磁束の一部を通過させるヨークを更に備える。【選択図】図1 |
