Rule ECO-Switch Automatic Bilge Pump Switch [39] Marine Plumbing & Ventilation | Hot Water Heaters 0-50 Amp AC AmmeterECO Switch The Rule ECO Switch is an ecologically sound automatic bilge pump control 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 switch. This air pressure activates the switch which controls your pump. There are no moving internal parts, all wiring is out of the water, and there are no submerged electrical connections at all.
