ABSTRACT:
A turnbutton latch has an improved male part comprising a hollow stud supting a turnbutton at one end of the stud. A bolt is fixed to the turnbutton within the stud, and a turnbutton spring biases the turnbutton to a closed position, at which the bolt depresses a trigger against the bias of a trigger spring. When the turnbutton is manually turned to open the latch, the trigger moves toward the turnbutton, blocking the bolt and preventing the turnbutton from closing the latch until the trigger is depressed. A female part placed over the turnbutton and the stud when the latch is open depresses the trigger to close the latch.
