It opens or closes an electrical circuit when the float rises or falls with the liquid, making it ideal for pumps, alarms, and automated liquid management systems in industrial, agricultural, and household applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this float switch compatible with both AC and DC systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This duckbill float switch supports a working voltage range of DC 0–220V and a working current of 0.5–1.5A, making it compatible with a wide variety of electrical setups, including both low-voltage DC and standard AC control circuits.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this stainless steel level sensor be used with corrosive liquids?\u003c\/h4\u003e\n\u003cp\u003eA: The sensor is constructed from SUS304 stainless steel, which offers good resistance to a range of acids, alkalis, and varying liquid densities. However, we recommend verifying compatibility with highly aggressive chemicals before use in extreme chemical environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I install the G1\/2\" duckbill float switch?\u003c\/h4\u003e\n\u003cp\u003eA: The switch features a standard G1\/2\" threaded fitting, allowing it to be screwed directly into a tank wall, pipe fitting, or vessel port. No separate power supply is required — simply connect the switch contacts into your circuit, and the reed switch will activate as the float detects the liquid level.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a duckbill float switch used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A duckbill float switch is a liquid level sensor used to detect and control the level of water or other liquids in tanks, pipes, and vessels.
