Claim:
A circuit breaker, comprising: a housing; a moveable contact blade positioned within the housing; a moveable contact directly attached to the moveable contact blade; a rotatable member pivotally coupled to the housing and having an axis of rotation about which the rotatable member is rotatable, the rotatable member further including a protrusion extending radially with respect to the axis of rotation, the protrusion having a first engagement surface portion and a second engagement surface portion next to the first engagement surface portion, the first engagement surface portion being substantially planar and the second engagement surface portion being substantially curved, the rotatable member being positioned adjacent to the blade such that as the moveable contact blade is moved from a first blade position to a second blade position the blade contacts the first engagement surface portion of the protrusion and causes the rotatable member to rotate about the axis of rotation such that the blade contacts the second engagement surface portion; and a biasing member operatively engaged with the rotatable member and the housing.
