Word Origin for switch
1590s, "slender riding whip," probably from a Flemish or Low German word akin to Hanoverian swutsche, a variant of Low German zwukse "long thin stick, switch," from Germanic base *swih- (cf. Old High German zwec "wooden peg," German Zweck "aim, design," originally "peg as a target," Zwick "wooden peg"), perhaps connected with PIE root *swei- "to swing, bend, to turn."
The meaning "device for changing the direction of something or making or breaking a connection" is first recorded 1797. "The peg sense suits the mech(anical) applications" [Weekley], and these senses may be a direct borrowing from those senses in Continental Germanic languages rather than a continuation of the "pliant wand" sense. The meaning "a change, a reversal, an exchange, a substitution" is first recorded 1920.
1610s, "to strike with a switch," from switch (n.). Related: Switched; switching. The meaning "turn off or on" is first recorded 1853 of trains on tracks, 1881 of electricity, 1932 of radio or (later) television. Sense of "shift, divert" is from 1860. Meaning "to change one thing for another" is recorded from 1919. Switch-hitter is 1930s in baseball slang, 1956 in the sense of "bisexual person."
asleep at the switch
Also, asleep at the wheel. Inattentive, not doing one's job, as in At the critical moment the watchman was asleep at the switch and only called the fire department when it was too late. This term came from 19th-century American railroading, when it was the trainman's duty to switch cars from one track to another by means of manually operated levers. Should he fail to do so, trains could collide. It was later transferred to any lack of alertness. The wheel in the variant is a steering wheel; similarly disastrous results are implied.
