Johnson Pump Marine Ultima Combo bilge pumps are JPM's proven Cartridge Bilge Pumps combined with the non-clogging electronic switch Ultima Switch for automatic operation. The electronic automatic switch Ultima Switch uses the patented Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by level of water present in the bilge and automatically activates and deactivates the pump.

Theory of Operation
The electronic automatic switch Ultima Switch uses the patented Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are totally sealed and are never in contact with the water, will not corrode and are not affected by oil or foreign debris.
