A slam-capable, flush-mountable, paddle handle operated rotary latch having a pan-shaped housing employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having spaced first and second housing side plates that sandwich the rotary jaw, the rotary pawl and a torsion spring that biases the jaw toward an open position, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining a suitably configured strike formation, with the first housing side plate being rigidly connected to the pan-shaped housing, and with the second housing side plate being rigidified in close proximity to its U-shaped notch by an integrally formed flange that extends transversely to bridge between the housing side plates. The pawl defines a release trigger which, when tripped, permits the jaw to be pivoted by the spring to an open position. An operating arm is connected to the housing for pivotal movement along a back wall of the housing for tripping the trigger in response to operation of the handle. The operating arm has opposed end regions, one of which engages the release trigger and is guided for movement by extending through a slot formed in the first side plate, the other of which is guided for movement by a backwall-mounted guide, and is engageable by a lockable cam for selectively permitting and preventing the handle and arm from moving to trip the trigger.
