Abstract: An electromagnetic relay includes: a coil; a bobbin; a core inserted into the bobbin; an armature; a first fixed contact; a first movable spring including a first movable contact configured to cause the first movable contact to move into and out of contact with the first fixed contact; a second fixed contact; a second movable spring including a second movable contact configured to cause the second movable contact to move into and out of contact with the second fixed contact; and a card configured to cause the second movable contact to move into or out of contact with the second fixed contact according to switching of the coil between an excited state and a non-excited state. The first movable spring includes a first end portion near the first end of the armature and a second end portion farther from the first end of the armature.

Abstract: An electromagnetic relay includes: a fixed terminal including a fixed terminal main body extending in a first direction, a fixed terminal arm portion, and two fixed contacts; a movable spring including two movable contacts, and extending in a second direction; a backstop; and a fixed terminal retainer. One of the fixed terminal main body and the fixed terminal arm portion is a first side terminal portion facing in the second direction, and the other is a second side terminal portion curving from a first edge of the first side terminal portion in a direction opposite to the second direction. A leg portion of the backstop is provided away from the first side terminal portion in the direction opposite to the second direction, and is provided between the two movable contacts on a projection plane with a perpendicular extending in the second direction when viewed from the first direction.
