A dual function two stage draw latch has a first stage loop member pivotally attached at one end to a latch lever pivotally mounted to a base member secured to a wall of a first container. A second stage loop member is pivotally attached to the other end of the first stage loop member. The free end of the second stage loop member is able to engage a catch mounted on a wall of a second container stacked on top of the first container to provide a holding force for the two containers. This free end is also able to engage a catch element mounted on a container lid to hold the lid in place. Electrically conductive strips interconnect the latch and catch to provide electrical interconnection between the containers.
