Now backed by a 5 years warranty, the non-mercury super switch is designed for the toughest applications. Design includes marine-grade 14 ga "blocked wire", larger float for increased buoyancy, removable base for easy servicing and a snap switch design capable of handling pumps drawing up to 20 A. A standard bilge pump operates by a control switch that senses water and activates the pump. Rule® 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 A, except the model 35 Rule-A-Matic, which is suitable up to 14 A. 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.
