Traditional public toilets have the complicated handles. we have to toilfully pull the door to keep the door and board in the same plane and rotate the door handle for locking. Now this handle is easily to operate ,you just need to turn the button gentlely which can control the internal spring automatically perpendicular spinning in 180 ° and closing the door completely.You don't need to shut the door in rotating the handle difficultly any longer.There is also a big hole in the door to show whether the bathroom is available by the red mark on the handle.
