Abstract
A contact shoe device for a circuit breaker is formed of a case, at least one pair of fixed contact shoes disposed in the case, at least one movable contact shoe disposed in the case for bridging the pair of the fixed contact shoes, and at least one pair of contact springs cooperating with the movable contact shoe. The contact springs urge the movable contact shoe to the pair of the fixed contact shoes to close an electric path between the pair of the fixed contact shoes. The movable contact shoe is separated from the pair of the fixed contact shoes against the contact springs when the electric path is open.
