North Carolina Locksmith Practice Exam

Question: 1 / 435

What does the Drive Cam do in a combination lock?

It secures the lock in place

It rotates the first wheel in response to the dial

The Drive Cam plays a crucial role in the operation of a combination lock by rotating the first wheel in response to the dial being turned. When the correct sequence is dialed, the Drive Cam engages with the wheel, allowing it to turn. This is a vital step in the unlocking process, as the movement of the first wheel must occur in precise relation to the other components of the lock to align the locking gears correctly.

In contrast, securing the lock in place or triggering the locking mechanism pertains to other components within the lock itself, which do not involve the Drive Cam's function. Additionally, the Drive Cam does not supply power to the lock mechanism, as traditional combination locks operate mechanically rather than electrically.
