Abstract
A position switch and a circuit breaker having a position switch are provided. Contact plates, each having an elastically variable height, may be provided between switch blocks and switch levers. A testing contact plate and a running contact plate may compensate for inferior dimensioning of the switch blocks and the switch levers. Such a configuration may allow a position of a breaker body to be quickly and accurately displayed and, further, may prevent damage of the position switch provided at the breaker body. Furthermore, such a configuration may prevent any connection inferiority between a terminal of the breaker body and a terminal of a cradle.
