What does switch mean?
Switch is a versatile word used for both physical controls and changes in direction. As a noun, it can refer to a device that turns a machine or light on or off, as well as an abrupt or significant change in plans, employment, location, or strategy. As a verb, it describes moving from one activity or arrangement to another, replacing one option with another, or transferring something between people or places. The phrase flip the switch is especially common for changing a light or machine from off to on, but switch has also developed a broad figurative meaning: people switch jobs, subjects, channels, gears, or strategies. In sports, switching can refer to changing direction, position, or tactics. Its usefulness lies in conveying a change that is noticeable and often immediate without specifying the cause or making the change sound especially dramatic.
A device or control used to turn something on or off, or a change from one course, method, or set of circumstances to another.
"The switch on the radio was stuck in the off position."

Where does switch come from?
The word switch comes from Middle English swiche, meaning a twig or flexible branch, and probably reflects an Old English or Anglo-Norman origin associated with flexible or branching material. Its development toward the modern meanings of a control device and a change of direction is recorded in English during the early modern period. The verb initially referred to changing or replacing something and later extended to changing place, position, activity, or direction.
