A micro switch is a sensitive switch characterized by its small travel distance and rapid action. It can open or close a circuit by applying minimal external force (such as pressing or triggering). Its core structure includes an operating head, a spring, a moving contact, a stationary contact, and a housing. After being triggered, the contact instantly switches 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.
