A cam lock is a rotating fastening mechanism commonly used in furniture and cabinet assembly. In cybersecurity and electronics contexts, cam locks are employed to physically secure and connect battery cells or other hardware components within devices. The cam lock consists of a cylindrical base with a metal 'cam' arm that rotates when the key or actuator is turned, locking or unlocking the mechanism. This simple yet effective design helps prevent unauthorized access or tampering with sensitive hardware, providing an added layer of physical security. Cam locks are valued for their ease of installation, reliability, and versatility in securing various enclosures or panels.
