Interlock systems are safety mechanisms designed to prevent certain actions from occurring until specific conditions are met. For example, in industrial settings, these systems ensure that machinery cannot operate unless safety guards are in place, reducing the risk of accidents. They are commonly used in various applications, including automotive safety features and manufacturing equipment. These systems can be mechanical or electronic, and they often involve switches or sensors that detect whether the necessary conditions are satisfied. By enforcing a sequence of operations, interlock systems help maintain safe working environments and protect both workers and equipment.
