A switch began life as something you could snap in your hand: a twig. Picture a rider in the 1590s carrying a thin whip, not a grand weapon, just a flexible little branch that could sting or steer. Then the word wandered into railways in 1797, when wooden tracks needed a piece that could send a cart one way or another; the humble twig had become a traffic cop. That same idea kept growing into the electrical switch, the computer switch, even the idea of switching sides. No wonder it feels so practical: a word for a stick turned into a word for change itself.
