The Rockwell Automation Trapped Key Interlock switches are used for electrical isolation of machinery to improve safe access and also as teach boxes in robot cells. Once the power has been turned off, the key can then be withdrawn and used in the next sequence of operation such as unlocking an access hatch or allowing valves to be operated. The rotary switch can either be mounted in a panel or purchased in an enclosure. IP20 rating
