  • latch 911 As latch 911 passes a ridge of the protrusion, a hole in latch 911 engages with the protrusion of the complementary connector causing the latch 911 to revert to its original horizontal position. This is the locked position of the latching device and the connector 900 is then firmly coupled to the complementary connector.
