1. A compression latch for a door comprising:
a driver that is rotatable with respect to the door between an unlocked position and a locked position, said driver being configured to be mounted to one side of the door,
a driver shaft that is non-rotatably connected to the driver such that said driver shaft rotates along with said driver in the same direction, the driver shaft having a proximal end non-rotatably positioned within a recess formed in the driver, and
a pawl assembly that is configured to be mounted to an opposite side of the door, said pawl assembly comprising (i) a housing that is configured to be fixedly mounted to the door, and (ii) a pawl that is movably connected to the housing and is configured to both rotate and translate with respect to the housing in response to rotation of the driver shaft,
wherein, in an unlocked position of the driver, the pawl is positioned to permit opening of the door, and, in a locked position of the driver, the pawl is positioned to prevent opening of the door, and
wherein the compression latch is configured to translate the pawl closer toward the door upon rotating the driver from the unlocked position to the locked position wherein the driver shaft includes a distal end that is non-rotatably connected to said pawl.
