ABSTRACT The velocity of a snap action, spring loaded vacuum switch closing mechanism is substan- tially reduced by impacting a lever of the mechanism against a first swingable energy absorbing arm which, in turn, pivots to contact a pair of second energy absorbing arms. The pair of second arms are lightweight relative to the first arm and swing through a greater arc than the latter to permit oscillations to subside in remaining components of the switch before rebounding against the first arm. The swingable arms absorb a significant portion of the kinetic energy of the mechanism during closing of the contacts so that shock waves which are nor- mally experienced in various components of the mechanism cannot combine to a value sufficient to snap the mechanism to an open circuit orientation. The anti-bounce device is particularly useful for three phase switchgear wherein a single, common mechanism functions to simultaneously close three pairs of electrical contacts. The closing mechanism has a latching member which cooperates with a latching pin to release the mechanism and close the switch when desired.
