Ultima Switch – Electronic Automatic Switch

The solid-state 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.

  • Limited 3 Year Warranty
  • No moving parts, totally sealed solid state electronics and field detectors
  • Environmentally sensitive; no mercury
  • No exposed sensors eliminate corrosion possibilities
  • Activates at a 50 mm (2″) fluid level and deactivates at a 20 mm (¾”) fluid level
  • A three second delay prevents false starts from water sloshing in the bilge
  • Ultima Switch is rated to handle pumps up to 20A at 12V or 10A at 24V.
