Year after year, the Rule-A-Matic has been the switch of choice for boaters the world over. Our latest design now includes a removable base for easy cleaning and servicing, a mercury free snap switch tested to over one million cycles and marine grade "blocked" wire. Designed for pumps drawing up to 14 Amps. Model 35A and 35FA now includes 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.

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.
