A latch assembly for use on a closure, e.g. a sash, the assembly comprising a housing from which a slidable, spring-biased latch bolt extends, an actuating handle pivotally mounted at one end in the housing for pivotal movement in a plane parallel to the plane of movement of the bolt and having an opposite end portion extending from a portion of the housing spaced from the portion of the housing from which the bolt extends and a pair of bolt-lifting levers pivotally mounted intermediate their ends within the housing, one end of each lever being engagable with the bolt and the opposite end of each lever being engagable by a projection on the handle intermediate its ends for withdrawing the bolt. When the handle is pivoted in one direction, one lever is engaged and lifts the bolt whereas when the handle is oppositely pivoted, the other lever is engaged and lifts the bolt. The levers are free to pivot when the bolt is pushed inwardly from externally of the housing.
