Claims

[Scope of utility model registration request]

In a circuit breaker comprising a conductor and a contact fixed to the conductor, and having a pair of movable and fixed electric contacts that open and close with each other, the conductor of the movable and fixed electric contact is connected to the center of the fixed part of the contact. The shafts are each bent into an L-shape so that the central axis of the contact is perpendicular to the surface of the contact, and the conductor of the movable electrical contact has a bend that creates a current path in the opposite direction to the fixed part of the contact. A circuit breaker characterized in that a curved part is formed and the outer periphery of the contact fixing part is covered with an insulator.
