A switch is a key electrical control device primarily used to control the limit positions of mechanical equipment motion. When a mechanical component reaches a preset position, the switch is triggered through physical contact, causing the circuit to close or open, thereby achieving precise position control and motion management.

This type of switch plays an important role in industrial automation and is commonly used to ensure that mechanical equipment operates within safe and predetermined ranges. Widely applied in automated production lines, robotics, lifting machinery, medical equipment, safety control systems, and other fields, limit switches are critical to improving production efficiency, ensuring safe equipment operation, and reducing maintenance costs.

In modern industries such as new energy, logistics, electronics manufacturing, and automotive manufacturing, limit switches serve as a fundamental and key component, playing an indispensable role.
