RELAY

A relay includes a contact container (10) including a yoke plate (13) and an insulating cover (11a connected with the yoke plate (13) to form a contact chamber (101); a pair of static contact leading-out terminals (20) passing through a pair of first through holes (102) of the insulating cover (11a); a fixing member (60) within the contact container (10) and fixedly connected with the yoke plate (13); a movable member (53) within the contact chamber (101) and including a movable contact piece (54) configured to come into contacted with or separated from the pair of static contact leading-out terminals (20); a moving part (80) movable connected to the fixing member (60); and a first magnetizer (40) connected with the moving part (80). Wherein the first magnetizer (40) is movable relative to the movable member (53) through the moving part (80) and is configured to adjust a distance between the first magnetizer (40) and the movable member (53) according to a value of a current flowing through the movable contact piece (54).
