Abstract

A circuit breaker having a contact opening and closing mechanism including a contact actuator member which is moved between a first position and a second position to close and open the contacts. The movable contact is mounted on one end of an elongated contact carrier which is connected in its central region by means of a pin and slot combination (providing a free floating coupling arrangement) to the contact actuator member. A compression spring is positioned between the contact actuator member and a portion of the contact carrier between the pin and slot combination and the other end of the contact carrier. When the contact actuator member is in the first position, the compression spring produces a torque in one direction about the other end of the contact carrier forcing the contacts closed. When the contact actuator member moves from the first position toward the second, the pin and slot combination become the pivot point and the direction of the torque produced by the compression spring is reversed thus enhancing the contact opening process.
