A movement switch is a control switch used in mechanical devices or electrical systems, responsible for precise operation and state switching of internal mechanical or electronic components. It is widely applied in clocks, household appliances, industrial equipment, and power tools, serving as the control unit of the device's core components. Movement switches typically feature high sensitivity, high precision, and long lifespan, enabling complex opening and closing actions in limited space. Some movement switches also integrate dustproof and waterproof functions, making them suitable for various working environments. Their design focuses on durability and reliability, ensuring stable performance and ease of operation over long-term use.
