Abstract: An electromagnetic relay includes a contact device, a movable member, a driving device, a return spring, and an insulating member. The contact device includes a first fixed terminal, a second fixed terminal, and a movable contact piece. The movable member presses the movable contact piece. The driving device is disposed on one side of a first direction with respect to the contact device and the movable member and moves the movable contact piece via the movable member to one side of a second direction intersecting the first direction. The return spring is disposed between the movable member and the driving device in the first direction for urging the movable member toward another side of the second direction. The insulating member separates the contact device from the driving device and has an opening where the return spring is inserted. The opening is open toward one side of the first direction.

Abstract: An electromagnetic relay includes a case including a base, a first fixed terminal held by the base, a movable contact piece, a gas inflow space, and a gas passage. The first fixed terminal includes a first fixed contact disposed apart from the base in a first direction inside the case, a contact support portion disposed between the first fixed contact and the base and configured to support the first fixed contact, and a first extending portion extending at an angle from the contact support portion and penetrating the base in the first direction. The movable contact piece includes a first movable contact facing the first fixed contact in the first direction. The gas inflow space is formed between the base and the contact support portion inside the case. The gas passage penetrates the base in the first direction and communicates the gas inflow space with an outside of the case.

Abstract: A contact device includes a fixed contact, a movable contact, a housing, and an arc extinguishing member. The movable contact moves between a closed position where the movable contact contacts the fixed contact and an open position where the movable contact is separate from fixed contact. The housing houses the fixed contact and the movable contact. The arc extinguishing member is movably disposed in the housing and discharges an arc extinguishing gas. The arc extinguishing member is disposed facing a gap between the fixed contact and the movable contact when the movable contact is in the open position.
