A standard bilge pump operates by a control switch that senses water and activates the pump. Rule’s Float Switches offer outstanding performance.

Extra-large float chambers are used 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.
