The limit switch is a switch used to detect and control the position of mechanical equipment, consisting of a movable active part and a fixed fixed part. When the movable part contacts an object or moves to a specific position, the switch will trigger a signal, thereby triggering a corresponding action or control. Limit switches are widely used in various mechanical equipment for monitoring and control. The position of moving parts to ensure the normal operation and safety of equipment. They play a key role in automation systems, such as in mechanical processing, conveying systems, automatic assembly lines, etc. There are two types of limit switches: contact and non-contact. Contact limit switch: Use mechanical contacts for motion detection. When the contacts touch the object, the circuit is closed or disconnected to generate a signal. This type of limit switch is usually used in applications that require high precision and reliability. Non-contact limit switch: Use non-contact sensing technology such as light, magnetism, and ultrasound for position detection. Signals can be triggered without physical contact.
