The KARI Float Switch is a cable suspended control device for filling and discharging pumps, motor and magnetic valves. It is also an alarm device at certain pre-determined surface levels.  Kari Float Switch consist of a free floating switch enclosure to which a protected multiconductor cable is attached. Inside the float there are a number of microswitches set at different angles. A control weight is fixed at a point along the cable to keep the cable immersed in the liquid. The suspended float switch follows the movement of the liquid level. As the liquid level rises and falls, the weight on the cable causes the inclination of the float to change. This tilting action results in microswitches opening and closing, sequentially, at different elevations. By separating the switching levels, turbulence problems are overcome. The switch operating levels are easily adjusted by moving the weight along the cable and/or altering the height of the cable fixing point.

Due to its large float casing the Kari Float Switch has a buoyancy which guarantees smooth, trouble-free operation under all conditions.
