More on Padlocks

As stated above previously, there are also two different locking mechanisms depending on the padlock. These two systems have been appropriately termed “integrated” and “modular”. The former simply and directly engages the shackle with the lock tumblers. Examples of this system are rotating disks – which are usually found in “Scandinavian-style padlocks – and level tumblers. This system is quite old-fashioned, and has given way to the more modern “modular” system. This locking system is the one most similar to most people today. It involves a plug within the lock, that turns and releases itself from the shackles with the use of the right key.
