| 摘要 |
The circuit breaker disclosed in the invention comprises a first connection terminal, a second connection terminal, a rotatable conducting part disposed between the first connection terminal and second connection terminal, a heat generating part, an igniting part igniting depending on a cut-off signal, an elastic member capable of producing a rotating force, and a holding part for holding the conducting part while resisting the rotating force of the elastic member. Herein, when the holding part releases holding of the conducting part as the igniting part ignites depending on the cut-off signal and the heat generating part generates heat, the conducing part is rotated by the rotating force of the elastic member, and the conductive state between the first connection terminal and second connection terminal is cut off.
