• 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 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;
