Abstract

A relay, including a first fixed contact, a second fixed contact, a movable contact piece having first and second movable contacts, a contact piece holding unit configured to hold the movable contact piece, a magnet for arc extinguishing, and a debris suction unit configured to exert a magnetic force to suck debris, is disclosed. A first contact position between the first fixed contact and the first movable contact is located between the magnet for arc extinguishing and the contact piece holding unit in a longitudinal direction of the movable contact piece. The debris suction unit is disposed so that the first contact position does not overlap a region between the debris suction unit and the contact piece holding unit. A magnet force exerted by the debris suction unit in the contact piece holding unit is larger than a magnetic force exerted by the magnet in the contact piece holding unit.
