Ensure precise and reliable liquid level control with this Double Ball Float Switch, crafted from durable 304 stainless steel for long-lasting performance and corrosion resistance. Designed for use in water tanks, pools, sinks, fish tanks, and other liquid containers, this float switch provides accurate upper and lower level detection with high-sensitivity reed switch contacts, making it ideal for both water intake and drainage applications. Key Features: · Durable 304 Stainless Steel Construction: Offers excellent corrosion resistance and durability for extended service life in various liquid environments. · Double Float Design: Features two floats with a 10mm action range, allowing precise control of liquid levels and reducing pump cycling by enabling a larger control stroke when used in combination. · High-Sensitivity Reed Switch Contacts: Ensures accurate and reliable switching with minimal power consumption. · Versatile Liquid Level Control: Suitable for controlling water tanks, pools, sinks, fish tanks, and other liquid containers for both filling and draining operations. · Requires Relay for High-Power Devices: Cannot directly control solenoid valves, high-power relays, or AC contactors; a small relay (e.g., HH54P) is needed for safe transition and operation. · Multiple Size Options: Available in floating body lengths of 100mm (3.94in), 150mm (5.91in), 200mm (7.87in), and 250mm (9.84in) to fit various installation requirements. · Simple and Effective Operation: The lower float activates normal water intake while the upper float stops it; conversely, the upper float activates drainage while the lower float stops it, providing reliable level management. Specifications: · Voltage: DC 0~110V · Material: 304 Stainless Steel · Floating Body Length Options: 100mm / 3.94in, 150mm / 5.91in, 200mm / 7.87in, 250mm / 9.84in Package Includes: · 1 x Double Ball Float Switch This Double Ball Float Switch is an essential component for precise liquid level control in various applications, delivering reliable performance and long service life thanks to its stainless steel construction and sensitive reed switch technology. Ideal for preventing frequent pump starts and ensuring efficient liquid management in your system.
