Abstract
A relay includes a movable contact piece having a movable contact, a fixed contact, a drive device configured to move the movable contact piece, a magnet to apply a Lorentz force to an arc in a first extension direction, a fixed terminal having an intermediate portion to apply a Lorentz force to the arc in a second extension direction, and a wall portion. The wall portion includes first and second wall surfaces. The first wall surface is disposed to face an arc-extinguishing space, and is disposed opposite to the movable contact and the fixed contact in the first extension direction. The second wall surface is disposed to face the arc-extinguishing space and is disposed downstream in the second extension direction with respect to the first wall surface. A distance from the movable contact piece to the second wall surface differs from a distance to the first wall surface.
