Ultima Switch™ - Electronic Automatic Switch

Patented Mirus field effect detector cells producing micro-electrical field 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. No moving parts, totally sealed solid state electronics and field detectors, no mercury and no exposed sensors eliminate corrosion possibilities and makes the Utima Switch environmentally sensitive. Activates at a 2" fluid level and deactivates at a 3/4" fluid level. A 3 second delay prevents false starts. Ultima Switch is rated to handle pumps up to 20 amp at 12 or 24 volt.
