Applications

AB switches like this were commonly used in serial data environments to route RS-232 communications between multiple devices and a single port. Typical applications include switching between modems, terminals, printers, and computer systems in laboratory, telecommunications, and industrial control settings. This configuration is found in legacy manufacturing, test equipment setups, and mainframe environments where manual port selection was required.
