ABSTRACT:
A latch assembly for use as a closure device in a door or compartment cover has a pan adapted to be flush mounted in an exterior panel, with a paddle-type handle hinge mounted within a recessed area of the pan. A mounting plate on an interior side of the pan includes a latch mechanism mounting flange which extends away from the pan, and to which a latch mechanism having a pawl and a trip latch jaw is mounted. A cam is rotationally mounted tightly parallel against the mounting plate, and has a paddle contact pin which extends through cooperating openings in the mounting plate and a floor of the pan. Lifting of the paddle causes the cam to rotate and engage the pawl of the latch mechanism, thereby releasing the trip latch jaw from a locked position. A lock cylinder may be mounted in the pan with a locking cam positioned proximate to a portion of the cam, to thereby interfere with rotation of the cam. The rotational mounting of the cam tightly against the mounting plate occludes the cooperating openings in the mounting plate and pan floor to prevent the passage of moisture or foreign objects to the interior of the latch assembly.
