A tilt-latch ( 10 ) for a sash window ( 12 ) is disclosed. The tilt-latch ( 10 ) has a housing ( 40 ) adapted to be supported by a top rail ( 20 ) of the sash window ( 12 ). The housing ( 40 ) has an outward end opening ( 58 ) and an aperture ( 68 ). A latch bolt ( 42 ) is disposed within the housing ( 40 ) and has a nose ( 88 ) adapted for engaging a respective one of the guide rails ( 16 ). The latch bolt ( 42 ) has an extended position, an intermediate position and a retracted position. An actuator ( 44 ) is connected to the latch bolt ( 42 ). The housing ( 40 ), the latch bolt ( 42 ) and the actuator ( 44 ) have cooperative structure such that the actuator ( 44 ) is connectable with the latch bolt ( 42 ) only when the latch bolt ( 42 ) is in the intermediate position. |
