LSF and RT switches are rated for 600V AC and 60V DC, eliminating the need for separate AC and DC components. Designed for DIN-rail and base mounting applications, the LSF Series supports an extended handle application where a shaft extends beyond the electrical box, and an external handle interlocks with it to prevent the box from being opened while power is on. Other technical features of the LSF/RT Series include: switch bodies made from high-grade plastics that resist shock and chemicals and can operate in a wide temperature range; silver contacts and rivets that ensure long life and better conductivity; and a spring-loaded design that prevents DC current from arcing and burning the contacts after repeated use. They are available in 16A, 30A and 40A versions and carry UL 60947-4-1 certification.
