What is the purpose of a limit switch?

• A. To prevent unintentional activation of controls
• B. To monitor battery levels
• C. To prevent certain parts of the unit from moving outside their safe working range
• D. To activate emergency protocols

Answer: (C)

The purpose of a limit switch is primarily to prevent certain parts of the unit from moving outside their safe working range. Limit switches are mechanical devices that provide feedback on the position of moving parts, ensuring that they operate within defined limits. By doing so, they help protect the equipment and its operators from accidents and damage caused by excessive movement. This functionality is crucial in environments where precise positioning is necessary to maintain safety and operational integrity. While other options suggest important functions, they do not directly align with the primary role of a limit switch in controlling movement and ensuring safety.
