What is the definition of a cam in locksmithing?

1. A rotating part of the bolt

2. A lock or cylinder component that transfers key motion to the bolt

3. A type of key used in locks

4. A safety mechanism in high-security locks

The correct answer is: A lock or cylinder component that transfers key motion to the bolt

In locksmithing, a cam is defined as a component in a lock or cylinder that is responsible for transferring the motion of the key to the bolt. When a key is inserted into the lock and turned, the movement of the key is conveyed through the cam, which then moves the locking bolt to either engage or disengage it from the strike plate. This mechanism is critical for the functioning of many types of locks, as it directly relates to how the lock secures or opens a door. Understanding this definition clarifies the role of the cam within the lock mechanism and its importance in ensuring effective locking and unlocking operations. Other choices do not accurately define a cam's function; for instance, while a rotating part of the bolt is indeed a component of some locks, it is not what defines a cam. Similarly, a type of key used in locks or a safety mechanism in high-security locks refers to different aspects of lock technology that are distinct from the cam’s role in facilitating the locking process.
