How does a trinary switch work?

A trinary switch operates using three distinct states rather than the typical two found in binary switches. It typically involves a mechanism that can connect to one of three different circuits or positions, allowing for more complex control options. This can be achieved through physical means, like a toggle switch with three positions, or electronically, using transistors or relays to manage the states. Trinary switches are often used in applications where more than two operational modes are required, such as in lighting or control systems.
