Wafer Lock

Wafer locks are a type of lock mechanism that, while less common than traditional pin-tumbler locks, serve specific purposes. Invented in the 19th century and patented in the early 20th century, wafer locks function similarly to pin-tumbler locks but with distinct differences. Unlike pin-tumbler locks, which typically consist of multiple pins stacked in a cylinder, wafer locks are simpler in design, often comprising a single piece.

The key components of a wafer lock include spring-loaded wafers that align along the lock cylinder. These wafers obstruct the rotation of the cylinder unless a key with the correct pattern of cuts is inserted. When the correct key is used, the wafers are pushed into the cylinder, allowing it to rotate and thereby unlocking the mechanism.

Wafer locks are widely used in file cabinets, drawers, and automotive locking systems. Their compact size and simple design are ideal for securing smaller compartments and containers where high security isn't essential. Despite their simplicity, wafer locks offer sufficient protection against unauthorized access. Chinese manufacturers play a key role in producing and distributing wafer locks globally.
