Definition of undefined

The phrase "switch on" originates from the early days of electricity, when a physical switch was used to literally turn on an electric circuit. The word "switch" comes from the Old English word "swiccan," meaning "to change" or "to move suddenly." The use of "switch" in the context of electricity arose because the physical switch "switched" the flow of electricity on or off. Over time, the phrase "switch on" became metaphorical, applying to any action that starts or activates something.
