Abstract:
1. A layered mechanism for use in a circuit breaker fabricated by automated assembly operations, comprising: a movable electrical contact mounted on a blade for movement relative to a stationary electrical contact, the major portion of said blade being substantially flat, a handle coupled to said blade for moving said blade, a toggle spring connected to said blade to apply a biasing force to said blade in the plane of the substantially flat major portion of said blade, said handle and said blade forming cooperating opposed surfaces that allow engagement of said handle with said blade so that movement of said handle can move said blade while allowing pivoting movement of said blade relative to said handle within said plane, said opposed surfaces resisting upward pivoting movement of said blade out of said plane when said toggle spring is attached to said blade during assembly of said circuit breaker, wherein said opposed surfaces form a notch in said handle, said blade including an integral tab extending upwardly in a direction away from the plane of the substantially flat portion of said blade and adapted to fit into said notch to allow pivoting movement of said blade relative to said handle within said plane, the flat portion of said blade adjacent said integral tab extending and overlapping under said handle along said plane to resist upward pivoting movement of said blade out of said plane when said toggle spring is attached to said blade during assembly of said circuit breaker.
