Description The Rule-A-Matic 35A is a float switch designed to automatically control non-automatic bilge pumps in marine installations. Suitable for pumps drawing up to 14 amps, it activates the pump when water rises in the bilge and switches it off once the water level has been reduced. Featuring a mercury-free snap switch mechanism tested to over one million cycles, the 35A model provides reliable long-term operation. The unit includes a removable base for easy cleaning and servicing, allowing debris removal without dismantling the wiring. Marine-grade blocked wiring enhances durability in harsh bilge environments. The Rule-A-Matic 35A is compatible with a wide range of bilge pumps, typically from 360 GPH up to 4000 GPH, depending on amperage draw. Interchangeable mounting bases (shared with model 37A) simplify replacement or upgrade installations. This model is backed by a 2-year manufacturer warranty.
