PROBLEM TO BE SOLVED: To provide a relay which can suppress damage due to heat of a pressing member caused when arc flows between contacts, while increasing the movement amount of the contacts.SOLUTION: A pressing member is provided on a first contact piece so as to press a portion between a first terminal and a first contact. The first contact comes into contact with a second contact when the pressing member moves from an off-position to an on-position so as to press the first contact piece in a direction toward a second contact piece. When the pressing member stops pressing, the first contact comes out of contact from the second contact due to elastic force by the first contact piece. At the same time, the pressing member is pushed back to the first contact piece so as to move from the on-position to the off-position. Before the pressing member reaches the off-position from the on-position, a restriction member restricts the movement of the first contact piece.SELECTED DRAWING: Figure 5 【課題】本発明の課題は、接点の移動量を大きくしながらも、接点間にアークが流れることによる押圧部材の熱による損傷を抑えることができるリレーを提供することにある。【解決手段】押圧部材は、第１接触片において第１端子と第１接点との間の部分を押圧するように設けられる。押圧部材が、オフ位置からオン位置に移動して、第１接触片を第２接触片に向かう方向に押圧することで、第１接点が第２接点に接触する。押圧部材による押圧が停止したときに、第１接触片の弾性力によって第１接点と第２接点とが非接触となると共に、押圧部材が第１接触片に押し戻されてオン位置からオフ位置に移動する。押圧部材がオン位置からオフ位置に到達する前に、規制部材によって第１接触片の移動が規制される。【選択図】図５
