Which mechanism provides a manual operation option through a rotating knob?

Spring Latch
Thumb Turn
Plug Spinner
Tension Wrench

The correct answer is: Thumb Turn

The option that provides a manual operation through a rotating knob is known as the thumb turn. This mechanism allows users to easily engage or disengage a lock simply by rotating the knob. It is commonly found on door locks, where turning the thumb turn from inside can allow for quick locking or unlocking without needing a key, making it particularly convenient in situations where quick access is desirable. A spring latch operates by using a spring to hold the latch in place and consequently does not have a knob for manual operation; it may be engaged or disengaged through a handle or the door being pushed or pulled. The plug spinner is a specialized tool used to manipulate the pins inside a lock, allowing unauthorized entry without manual operation through a knob. Lastly, the tension wrench is utilized in lockpicking to apply tension to the lock cylinder but does not provide a method for manual locking or unlocking through a rotating knob.
