Mechanical Digital Combination

A mechanical digital combination lock is a mechanical lock that uses a digital password to open. It usually consists of a dial wheel that rotates automatically, a set of dial codes, and a mechanical device that controls the lock body. The user needs to turn the dial on the dial to the correct position in the correct order in order to open the lock.

Compared with traditional key locks and electronic combination locks, mechanical digital combination locks have several advantages. First, it doesn't require batteries or a power source, so there's no need to replace batteries on a regular basis. Second, mechanical digital combination locks can be used in harsh environments, such as high, low, or humid conditions, while electronic locks may fail. In addition, mechanical digital combination locks are more difficult to pick or break than electronic locks because there are no circuits or electronic components for an attacker to exploit.
