1. A latch comprising:
a housing having a first side and a second side;
a bolt assembly positioned at least partially within the housing, the bolt assembly including a bolt movable longitudinally within the housing between a first position and a second position;
a bolt locking assembly, wherein the bolt locking assembly has an engaged position and a disengaged position, wherein when in the engaged position, the bolt locking assembly interfaces with the bolt to prevent movement of the bolt between the first and second positions and, when in the disengaged position, the bolt locking assembly allows movement of the bolt, and wherein the bolt locking assembly is linearly movable relative to the housing between the engaged and disengaged positions and biased toward the engaged position by at least one bolt locking assembly spring;
a bolt spring in contact with the bolt, wherein the bolt spring biases the bolt toward at least one of the first position and the second position;
a bolt movement assembly, including:
a locking cylinder mechanism movable between a locked position and an unlocked position, the locking cylinder mechanism being connected to the bolt locking assembly, the locking cylinder mechanism being accessible from the first side of the housing;
a control connected to the bolt locking assembly, the control being accessible from the second side of the housing, wherein, when actuated, the control moves the bolt locking assembly between the engaged and disengaged positions;
a cam connected to the locking cylinder mechanism, the cam interfacing with an inner surface of the bolt locking assembly and configured to rotate with the locking cylinder mechanism, wherein when the cam engages with the inner surface of the bolt locking assembly, the cam moves the bolt locking assembly to the disengaged position by moving the bolt locking assembly against the bias of the at least one bolt locking assembly spring, and
wherein, when the bolt locking assembly is disengaged from the bolt, the bolt is moved within the housing initially only by an external force between the first position and the second position, and wherein the movement of the bolt is partially assisted by the bolt spring toward one of the first or second positions of the bolt.
