Abstract
The double action latch employs a strike with two latches and a stop on the opposite side of the latches. The handle actuates a pivotally mounted bracket unit to cause a roller to ride over the first latch while moving a plate into a plate into engagement with the stop. This brings the door into a partially opened position, for example, for venting an oven. The handle is returned to the upright position and then a second pull is effected to move the roller over the second latch so as to permit the door to be fully opened.
