ABSTRACT:
A miniature circuit breaker includes an elastic contact piece to contact with two terminals of a circuit, thereby electrically connecting the circuit. One end of the elastic contact piece fixed to a terminal is a fixed end, and the other end of the elastic contact piece is a free end. The portion of the elastic contact piece close to the fixed end is bended to form an elastic curved section, which is capable of deforming and resuming an original state after deformation. Because of the elastic curved section, the elastic contact piece is capable of deforming, deflecting, and resuming the original state after deformation. Therefore, the length and size of the elastic contact piece can be reduced, and the circuit breaker is miniaturized.
