Abstract: A lockable latching device includes a body defining a cavity and a plunger disposed within a cavity defined in the body. The plunger is translatable with respect to the body between an open position and a closed position. The lockable latching device also includes an annular rotator configured for rotating the plunger about a central longitudinal axis, and an annular latch transitionable between an unlocked state and a locked state. The lockable latching device further includes first and second elements. The lockable latching device also includes a force transmission mechanism operably connected to the first element, the second element, and the annular latch, with the force transmission mechanism configured to transition the annular latch from the unlocked state to the locked state in response to a first activation signal, and to transition the annular latch from the locked state to the unlocked state in response to a second activation signal.
