W.E. Anderson L4-AT Series L4 Flotect Float Switch, ATEX Approval

Series L4 FLOTECT Float Switch, ATEX Approval

Magnetically Operated Switch, Leak Proof Body, Explosion-Proof

Rugged and reliablethe Series L4 Flotect® Float Switch operates automatically to indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or actuating level alarm signals. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, the free-swinging float attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm. Float arm hinge design limits the arm angle to prevent vertical hang up.
