The Rule Eco Switch is a remote mounted bilge switch which operates the bilge pump through the use of compressed air. The switch itself is mounted to the bulkhead high up above the bilge water level, while a tube runs down and connects to a plastic bell which sits in the water. As the bell fills up, the air in the bell and tube compresses and once a certain level is reached the switch operates the bilge pump.

All this means that no switch electronics are submerged in the water making the switch safe and reliable. The system is accurate and eliminates the need for a mercury float as in many bilge pump switches.
