How do combination locks work

You're probably curious about how combination locks work. They consist of a set of wheels, and their number depends on how many digits there are in the combination. Also, there’s a dial that connects to the spindle. The spindle travels via numerous wheels and a drive cam inside the lock. It turns the drive cam as you turn the dial. A drive pin is attached to the drive cam. The drive pin makes contact with a little projection on the adjacent wheel called the wheel fly when the cam rotates. On each side of each wheel, there is a fly. The drive pin rotates the first wheel until it comes into contact with the adjacent wheel. This process continues until all of the wheels begin to turn. This is referred to as wheel matching. When you use the proper combination, the wheels and notches align perfectly. When all wheels are aligned, the notches of the wheels line up and generate a gap. This gap in a padlock allows the locking bolt to be unfastened.
