Circuit breaker

摘要

Disclosed are a circuit breaker. As contact plates having an elastically variable height are provided between switch blocks and switch levers, each of a testing contact plate and a running contact plate may compensate for inferior dimensioning of the switch blocks and the switch levers. This may allow a position of a breaker body to be rapidly and precisely displayed, and may prevent damage of the position switch provided at the breaker body. Furthermore, connection inferiority between a terminal of the breaker body and a terminal of a cradle may be prevented.
