Relay

A relay, comprising:

• a contact container having a contact chamber and a pair of first through holes in communication with the contact chamber;
• a pair of static contact leading-out terminals passing through the pair of first through holes, respectively;
• a moving part movable relative to the contact container;
• a first magnetizer arranged within the contact chamber and connected with the moving part;
• and
• a movable member movably arranged within the contact chamber and comprising a movable contact piece and a second magnetizer, the movable contact piece configured to come into contacted with or separated from the pair of static contact leading-out terminals;
• the first magnetizer being arranged at one side of the movable contact piece facing the static contact leading-out terminals, and the second magnetizer being fixedly connected to one side of the movable contact piece facing away from the first magnetizer, and the second magnetizer is configured to form a magnetic circuit together with the first magnetizer;
• wherein the first magnetizer is movable relative to the movable member through the moving part and is configured to adjust a distance between the first magnetizer and the second magnetizer according to a value of a current flowing through the movable contact piece.
