Claim:
1. A hatch assembly attachable to a roof of a vehicle, comprising: a removable dome attached to a frame including opposed first and second linkage mechanisms and a latch assembly; the frame mountable in an opening through the roof of the vehicle and including an annular sidewall section defining an aperture and an outwardly extending flange portion peripheral to the annular sidewall portion; the annular sidewall section including a continuous upper peripheral surface; the dome having an outer planar surface covering the aperture and an inner surface including a tubular sleeve, wherein the tubular sleeve is inserted into a tubular sleeve member of the first linkage assembly; a latch keeper attached to the second linkage assembly; a latch assembly attached to the inner surface of the dome on a side of the dome that is opposed to the tubular sleeve, the latch assembly rotatably coupled to a lock wedge, the lock wedge including a helical locking surface; the lock wedge disengaged from the latch keeper when the latch assembly is at a first position associated with a first limit of rotational travel; the lock wedge engaged with the latch keeper to urge the latch keeper to a second position when the latch assembly is rotated to a second, opposed limit of rotational travel; the dome seated onto the frame when the first and second linkage mechanisms are in closed positions and the latch assembly is at the second position; and a position sensor coupled to the latch keeper and a sensor activation tab coupled to the lock wedge, wherein the sensor activation tab is disposed to interact with the position sensor only when the lock wedge engages the latch keeper and urges the latch keeper to the second position.
