A key operated latch (10) includes a housing which supports a lock plug (111 ), a motion control sleeve (40), and a sleeve-like cam (20) therein. The cam (2 0) rotates with the lock plug (111), while the motion control sleeve (40) is stationary. The cam (20) has at least one cam slot, and the motion control sleeve (40) has at least one motion control slot. A shaft (50) extends outwa rd from the housing and has at least one projection which is engaged with both the cam slot and the motion control slot. The cam slot and the motion contro l slot are configured such that rotation of the lock plug imparts a sequence o f rotational and axial movements to the shaft (50). A latching member (70) attached to the shaft, moves between a latched position and an unlatched position in a sequence of axial and rotational motions in order to selective ly secure a door, panel, or the like in the closed position.
