A door latch assembly is provided with a pushbutton actuation to release a lever plate from a pawl so that a door can be opened by free rotation of the pawl relative to a keeper. The lever plate is pivotally mounted within a housing which is secured with a base plate to the surface of the door, and the lever plate is normally urged into latching engagement with the pawl. The pushbutton contacts one end of the lever plate so as to move it out of engagement with the pawl. A separate releasing means, operable from an opposite side of the door from the position of the pushbutton means, contacts an opposite end of the lever plate so as to release the lever plate from the pawl without affecting the position of the pushbutton means. Thus, it is possible to release the door from the inside of a room even if the pushbutton means has been locked in a fixed position.
