ABSTRACT:
A padlock with a status indicator includes two locking units. The two locking units operate independently to execute locking and unlocking operations. The lock has a body that contains an indicator in the lock underneath. After the execution of the unlocking operation has been done sequentially, the indicator switches from an indication position to the other indication position. Thus through the window, which is formed on the body surface and corresponding to the indicator location, the indication positions of the indicator may be recognized.
