Question: 1 / 435

What is the role of the lever nose in a combination lock?

To rotate the dial

To secure the locking mechanism

To engage with the drive cam during operation

The lever nose in a combination lock primarily serves to engage with the drive cam during operation. When the correct combination is dialed in, the lever nose interacts with the drive cam, allowing it to move and disengage the locking mechanism. This interaction is essential for the proper functioning of the lock, as it directly connects the user’s input through the dial to the internal locking components.

Understanding this mechanism is crucial for a locksmith because it highlights the relationship between the user’s action (turning the dial) and the lock's response (the unlocking action). This knowledge can help troubleshoot issues related to the combination lock and inform the locksmith's approach to repairs or adjustments.
