A dampening assembly is for an electrical switching apparatus, such as a circuit breaker. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, and an operating mechanism structured to open and close the separable contacts. The dampening assembly includes a D-shaft pivotably coupled to the housing, and an anti-bounce assembly. The anti-bounce assembly includes a first element coupled to the housing, and a second element, such as an elongated resilient pin member, which is adapted to cooperate with the D-shaft to resist undesired movement of the D-shaft. The D-shaft has opposing first and second ends and a recess disposed between the first end and the second end. A portion of the elongated resilient pin member is disposed in the recess.
