When the water rises or falls to a set point, the float triggers a connected device such as a pump, alarm, or indicator. It's commonly used in aquariums, hydroponics systems, water heaters, humidifiers, and home appliances.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this float switch work with 220V systems?\u003c\/h4\u003e\n\u003cp\u003eA: This switch supports switching voltages up to 110V DC directly. For 12V, 24V, or 220V systems at higher loads, you will need to pair it with an appropriately rated relay — this is not included but is a standard, easy-to-source component.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this float switch suitable for saltwater or chemical tanks?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The PP plastic material offers strong resistance to acids, alkalis, and fungi, making it suitable for saltwater aquariums, freshwater tanks, and many chemical-resistance applications. The heat-resistant lead wires also hold up well against oils and humid environments.\u003c\/p\u003e\n\u003ch4\u003eQ: How is the float switch installed?\u003c\/h4\u003e\n\u003cp\u003eA: The duckbill bracket design allows for flexible mounting in various orientations. Installation is straightforward — attach the duckbill to the tank wall or fitting at your desired water level, connect the lead wires to your circuit or relay, and the switch will automatically respond to rising and falling water levels.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
