A cabinet lock has an elongate body. An operating handle is connected to the body for pivotal movement about an axis that extends transverse to the length of the body. The body slidably mounts (1) a spring-projected latch bolt for linear movement along a path of travel that substantially parallels the axis of pivotal movement of the handle, and (2) an operating member for linear movement along a path of travel that substantially parallels the length of the body. The handle has a formation that drivingly engages the operating member for moving the operating member from a latched position to an unlatched position in response to pivotal movement of the handle from a nested position to an operating position. A key cylinder is rotatably mounted on the housing and carries a stop formation that is operable (1) when the key cylinder is in an unlocked position to permit sliding movement of the operating member along the body in response to movement of the operating handle from its nested to its operating position, and (2) when the key cylinder is in a locked position to retain the operating member in its latched position and to retain the handle in its nested position. The slide bolt retracts from its normally projected position in response to movement of the operating member from its latched to its unlatched position.
