Bilge pumps operate with Bilge pump switches. The switch operates by a control switch that senses water and activates the pump. Rule Bilge Pump switches 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.
The float switches include 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 include a 2-year warranty.
