Series L4 FLOTECT Float Switch

Brand: Dwyer Instruments, LLC
Does not ship to OH, United States
Rugged and reliable the 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.
