Series L4 FLOTECT Float Switch
Brand: Dwyer Instruments, LLCRugged 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.
