An integrated lock and lilt-latch mechanism for a sliding window combines ease of installation and adjustment with simplicity of use at a low cost. The mechanism includes an actuator assembly operably connected by a flexible linking member to at least one tilt-latch mechanism adapted for mounting in a window sash. The tilt-latch mechanism includes a housing and a plunger having a latch-bolt portion retractable within the housing. A plunger-latch member automatically latches the plunger in a retracted position to enable tilting of the sash. The tilt-latch may include a locking member, adjustable from outside the housing of the tilt--latch, to lock the flexible linking member to the plunger, thereby operably coupling the actuator mechanism with the tilt-latch. The actuator assembly also includes a control lever that rotates a sweep cam and a selectively rotates a spool, thereby locking or unlocking the sliding window or actuating the tilt-latch mechanism. At least one biasing member causes the control lever to favor locked or unlocked positions over intermediate and tilt positions.
