Abstract
A door lock mechanism that rotates a cam mechanism to lock or unlock an enclosure. The mechanism includes a bias member that is coupled to the cam mechanism with a cam pin, where the cam pin is located on one side of the centerline of the lock in the locked state, and on the other side of the centerline of the lock in the unlocked state, to bias the cam mechanism into either the locked or unlocked state. Further disclosed are one or more stop mechanisms that prevent the cam mechanism from over-rotating past the locked or unlocked position. The bias member can further absorb impact from the lock rods of the door lock mechanism contacting the stop mechanisms.
