1. A latch assembly, comprising:
a housing configured for mounting to a door;
a latch bolt mounted in the housing for axial movement along a longitudinal axis between a projected position and a depressed position relative to the housing;
a roller engaged with the latch bolt such that the axial movement of the latch bolt from the projected position to the depressed position engages a drive surface of the latch bolt against the roller to urge the roller from a first position toward a second position; and
a locking sleeve movably mounted to the housing for movement relative to an axis via an actuator, the locking sleeve having a recess operable to partially receive the roller, and the locking sleeve having a blocking surface operable to engage the roller to prevent movement of the roller from the first position to the second position;
wherein the locking sleeve is displaced relative to the axis between a locking position in which the blocking surface is aligned with the roller and engages the roller to prevent movement of the roller from the first position to the second position and thereby retain the latch bolt in the projected position, and an unlocking position in which the recess is aligned with the roller to permit movement of the roller from the first position to the second position and into the recess to thereby enable depression of the latch bolt; and
wherein the locking sleeve is slidably mounted to the housing for axial movement along the axis via the actuator, and wherein the locking sleeve is axially displaced along the axis between the locking position and the unlocking position.
