Basic Mechanism: An internal door latch consists of a latch bolt and a spring-loaded mechanism. When the door handle is turned, the spindle connected to the handle rotates, pulling back the latch bolt. Latch Bolt Action: The latch bolt retracts into the door, allowing it to open. Releasing the handle allows the spring to push the latch bolt back out, securing the door in the frame. Strike Plate Interaction: The latch bolt engages with the strike plate on the door frame to keep the door closed.
