A micro switch is a sensitive switch characterized by its small travel distance and rapid action. It can achieve circuit on-off by applying minimal external force (such as pressing or triggering). Its core structure includes an operating head, spring, moving contact, stationary contact, and housing. After triggering, the contact will instantly switch states, and it can return to its initial position after resetting. It features fast response, high precision, and strong reliability. Its main applications include: detection machines, printers, electronic scales, juicers, vacuum cleaners, aromatherapy machines, and mice.
