Abstract
A knob assembly with lock and a status indicator is mounted in a toilet stall door and has a tubular lock, an indicator and a battery container. The tubular lock is mounted through door. The indicator is mounted on an outer surface of the tubular lock. When the toilet stall door is locked, the indicator emits light. Consequently, people are able to determine the door is locked. With a clear and visible indication that the toilet stall door is locked, people will not push the door so the door will not be damaged.
