A limit switch is an essential electrical component used to detect the presence or position of an object, ensuring that machines and equipment operate within specific limits. Typically employed in automation systems, limit switches work by triggering an action when an object or part of a machine reaches a predetermined point. This makes them crucial for safeguarding mechanical systems, preventing overtravel, and ensuring the proper functioning of various processes. Available in a variety of designs, including mechanical, electrical, and magnetic types, limit switches can be tailored to suit different industrial applications, including conveyors, robotics, and lifts.
