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. Float arm hinge design limits the arm angle to prevent vertical hang up.

Features

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
