Model Number: 40A
Model Name: Rule-A-Matic Plus with shield
Sleek and rugged, the Rule-A-Matic Plus float switch has a strong, fully integrated, impact resistant cover that protects against debris and jamming. It features 14 gauge highly abrasive resistant marine grade wire and a built-in test feature. Designed for pumps drawing up to 20 Amps. Both the 40A and 40FA now include a 2 year warranty.
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.
