Newly FAA ETL certified, the Airport Lighting Company L-847 Circuit Selector Switch (CSS) provides the connection between the output of a single constant current regulator (CCR) to switch that output to multiple airfield series circuits, economically and dependably.

With the introduction of our L847 CSS, Airport Lighting Company has incorporated the latest technology to offer a state-of-the-art CSS that can switch CCR output to up to four (4) series circuits. These CSS’s can also be used as an interface device with standby CCR’s in the case of a CCR being out of service or in an emergency. The dead-front cover with an inner clear safety guard protects the user from the high voltage components. These CSS’s are also usable for switching CCR output to PAPI’s, stop bars and REILS.  Our CSS will meet your requirements and provide the versatility for switching multiple circuits.
