Relay

A relay, comprising:

• an insulating cover 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 fixing member comprising a fixing part and a connector, the connector has a tubular structure, one end of the connector in an axial direction is fixedly connected with the insulating cover, and the other end of the connector in the axial direction is connected with the fixing part;
• a moving part arranged within the contact chamber and movably connected to the fixing part;
• 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, 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;
• 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 movable member according to a value of a current flowing through the movable contact piece.
