Abstract
A relay includes: a pair of fixed terminals, each being arranged to have a fixed contact on a one-end face; a movable contact member arranged to have a pair of movable contacts that are correspondingly opposed to the respective fixed contacts; and a driving structure operated to move the movable contact member. In a moving direction of the movable contact member, a side where the fixed contacts are located is called a first side, and a side where the movable contacts are located is called a second side. The movable contact member includes: a center section located between the pair of movable contacts and located on the second side relative to the movable contacts; and a pair of extended sections located between the center section and the pair of movable contacts and extended in a direction including a component of the moving direction. At least one of the pair of extended sections has a specific relationship of being overlapped at least partly with the one-end face located on same side relative to the center section in vertical projection of the relay onto a predetermined plane perpendicular to the moving direction.
