Safety interlock systems are designed to prevent dangerous operations in machinery and equipment. They ensure that certain conditions are met before a machine can be activated, reducing the risk of accidents. For example, a safety switch may prevent a machine from starting if a guard is not in place, ensuring that operators are protected from moving parts. These systems are commonly used in various industries, including manufacturing and construction. By integrating sensors and control circuits, safety interlocks help maintain a safe working environment. Regular testing and maintenance of these systems are essential to ensure their effectiveness and reliability.
