Mechanical interlocking

Mechanical interlocking is a safety feature used in electrical systems to ensure that certain devices or switches can only be operated under specific conditions, preventing accidents or equipment damage. It involves physical components—like pins, levers, or mechanisms—that block or allow movement based on the position of other parts. For example, in a circuit breaker system, one switch might be prevented from closing if another component isn’t in the correct state, ensuring safe operation sequences. This interconnection of mechanical parts enforces proper operation and enhances safety by mechanically preventing conflicting or unsafe actions.
