A blowout latch includes a rotatable bolt that secures a first panel that is adjacent to a second panel to which the latch is affixed. The bolt is restrained by a toggle linkage that operates at one end of the bolt against a pressure-actuated spring. The linkage will release the bolt when an excessive opening force against the bolt exceeds a selected restraining force of the spring. When that condition occurs, the linkage will have deflected the spring and moved to a position where the end of the linkage bearing against spring loses it mechanical leverage with respect to the bolt. Thereafter, the bolt is free to continue rotation to a fully open position. The latch also includes a manual trigger release that disables the restraining linkage and permits free rotation of the bolt to the fully open position when this trigger is actuated.
