Trapped Key Interlock SwitchesThe ideal solution for interlocking of hatches, guards and doors on machines in remote or intrisically safe locations.
The Rockwell Automation Safety Products Guardmaster™ Bulletin family of Prosafe™ trapped-key interlock switches are designed to provide power isolation, key exchange and interlocking for safety applications requiring a pre-defined sequence of operations.
The Prosafe™ range rugged products do not require power to operate which makes them the most practicable and reliable method of safety power interlocking for installations in industrial, process, petrochemical, nuclear, automotive and machine tool environments, where safe entrance to enclosures is required following the electrical isolation of machinery.
