Abstract
An integrated panel control in which both the release and pulldown mechanisms are controlled by a single operator activated switch. Initial operator activation of the switch when the panel is closed energizes the release mechanism through a latch switch which indicates that the latch bolt and striker are mechanically coupled. Initial operator activation of the switch when the panel is open activates the motor of the pulldown mechanism through the latch switch in initiate a pulldown of the panel. A second activation of the switch during the pulldown aborts the pulldown sequence by reversing the pulldown motor, freeing a spring or other device to re-open the panel. A second activation of the switch after the latch bolt and striker are mechanically coupled energizes the release mechanism through the latch switch to uncouple the latch bolt from the striker, freeing a spring or other device to open the panel.
