A dampening assembly (100) is for an electrical switching apparatus (2), such as a circuit breaker. The electrical switching apparatus (2) includes a housing (4), separable contacts (6) enclosed by the housing (4), and an operating mechanism (8) structured to open and close the separable contacts (6). The dampening assembly (100) includes a D-shaft (102) pivotably coupled to the housing (4), and an anti-bounce assembly (200). The anti-bounce assembly (200) includes a first element (202) coupled to the housing (4), and a second element (204), such as an elongated resilient pin member (204), which is adapted to cooperate with the D-shaft (102) to resist undesired movement of the D-shaft (102). The D-shaft (102) has opposing first and second ends (104,106) and a recess (108) disposed between the first end (104) and the second end (106). A portion of the elongated resilient pin member (204) is disposed in the recess (108). |
