• Dual-Point Water Level Control – The dual-float design enables both water intake and drainage automation, with the lower float activating fill operations and the upper float stopping them – while drainage is triggered by the upper float and halted by the lower one.
• High-Sensitivity Reed Switch with 10mm Action Range – Built with a precision reed switch inside for rapid response to liquid level changes. Each float triggers within a tight 10mm action range, delivering accurate on/off switching for consistent water level management.
• Rugged 304 Stainless Steel Construction – Crafted from 304 stainless steel. The durable floating body (250mm / 9.84in length) ensures long-term reliability in demanding environments like swimming pools, sump pumps, gardens, and industrial tanks.
• Reduced Pump Cycling: Combining two switches extends control range up to 250mm floating body length. Minimizes pump activation frequency, lowering energy use and mechanical strain. Prevents frequent starts in water systems, ensuring efficient operation for stable tank and pool level management
• Versatile Liquid Level Sensor for Multiple Applications – This dual ball float switch functions as both a water level controller and an upper/lower limit alarm switch. Ideal for water tanks, swimming pools, sinks, aquariums, ponds, and pump systems.
• Relay-Compatible System Integration – The float switch is designed for integration with control systems – it cannot directly drive solenoid valves, high-power relays, or AC contactors. A small relay (such as HH54P) is required for transitioning to higher-power loads.
