Until now there have been three varieties of float switches: vertical, tethered and pressure. Unfortunately, all three of these switches are subject to various forms of failure. Now a float has been created with redundant switches to eliminate these problems. The Dual Float has, not one, but two floats mounted within a protective cage. Should one float fail to operate, the second float is available and ready to activate the pump. The protective cage prevents debris or other wires from interfering with movement of the floats. Dual Float Level Switch
