Johnson Pump Ultima Switch Auto Control with Mirus Field Effect Detector Technology

Ultima Switch

New digital technology uses the Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are totally sealed, are never in contact with the water, will not corrode and are not affected by oil or foreign debris.

ULTIMA activates at a 50 mm (2") fluid level and deactivates at a 20 mm (3/4") fluid level. A 3 second delay prevents false starts. ULTIMA switch is rated to handle all Johnson Pump submersible pumps pumps up to 20 amps at 12 or 24 volts.

Features:

• No moving parts
• Totally sealed solid state electronics and field detectors
• No mercury
• No exposed sensors eliminate corrosion possibilities
• Unique 3-way switch disables piezo alarm while keeping warning LED lit
• Environmentally sensitive
  
  

The Johnson Pump Ultima Switch (Part Number 36303) offers advanced, reliable water level detection with innovative Mirus field effect detector cells. Designed for seamless operation in demanding environments, this switch utilizes new digital technology that produces micro-electrical fields to detect disruptions caused by water and other fluids. The detector cells are fully sealed, eliminating contact with water, preventing corrosion, and making them unaffected by oil or debris, ensuring long-term durability and maintenance-free performance. Ideal for managing submersible pumps up to 20 amps at 12 or 24 volts, the Ultima Switch activates at a 50 mm (2-inch) fluid level and deactivates at a 20 mm (3/4-inch) level, with a 3-second delay that prevents false triggering. Its solid-state electronics provide a reliable, environmentally sensitive solution that reduces the risk of failure common in traditional mechanical switches. The switch features a unique 3-way control that allows disabling the piezo alarm while still illuminating the warning LED, giving operators flexible control over alarm notifications. Perfect for marine, industrial, and agricultural applications, the Johnson Pump Ultima Switch is a smart, maintenance-free choice for water level management, combining advanced technology, environmental sensitivity, and ease of use.
