The Rule ECO-Switch is an ecologically sound automatic bilge pump control switch. Featuring a non-mercury design, the pump operates with simple air pressure. As water rises in the bilge, air rises in the air tube that is attached to the switch. This air pressure activates the switch that controls the pump. There are no moving internal parts, as all wiring is out of the water, which means that there are no submerged electrical connections at all. Offering complete reliability and outstanding performance, the Rule ECO-Switch offers a viable alternative to traditional float switches.
A standard bilge pump operates by a control switch that senses water and activates the pump. Rule’s Float Switches offer outstanding performance. We use extra-large float chambers for increased buoyancy and detachable mounting bases that make them easier to install and remove for cleaning and inspection. All models are suitable for pumps that draw up to 20 amps, except the Model 35 Rule-A-Matic, which is suitable up to 14 amps.
Rule also produces the ECO-switch, which operates when rising bilge water levels increase air pressure. All switching gear is located outside of the bilge in a sealed, compact unit.
