What is a key interlock system?

A key interlock system is a safety mechanism used to ensure that certain actions or equipment cannot be operated unless specific conditions are met, typically involving the use of physical keys. These systems often require that a key be inserted and turned to enable a machine or process, preventing operation under unsafe conditions. Key interlocks are commonly used in industrial settings to enhance safety by controlling access to hazardous areas or machinery. By enforcing a sequence of operations, they help prevent accidents and ensure that operators follow established safety protocols.
