Built from durable polypropylene (PP) plastic, this compact liquid level sensor uses a magnetic reed switch mechanism to automatically open or close a circuit as the liquid rises or falls — no external power supply or complex wiring required.\u003c\/p\u003e\n\n\u003cp\u003eIdeal for home water tanks, aquariums, sump pumps, dyeing equipment, food processing lines, hydraulic machinery, petrochemical systems, and more. Its simple mechanical design means fewer failure points and a longer service life compared to electronic-only alternatives.\u003c\/p\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe float ball rises and falls with the liquid level. Inside the sealed non-magnetic tube, a magnetic reed switch activates when the float's internal magnet comes close — completing the circuit. When the float moves away, the circuit opens. The clamp can be removed and the float flipped downward to reverse the switching action (open or close on water outlet).\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFloat Ball Material:\u003c\/strong\u003e Polypropylene (PP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFloat Body Material:\u003c\/strong\u003e Polypropylene (PP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Contact Rating:\u003c\/strong\u003e 10W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Switching Voltage:\u003c\/strong\u003e 220V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Switching Current:\u003c\/strong\u003e 0.5A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Breakdown Voltage:\u003c\/strong\u003e 220VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Carry Current:\u003c\/strong\u003e 1.0A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Contact Resistance:\u003c\/strong\u003e 100mΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -10°C to +60°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e Low voltage — below 50VAC or 75VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Concern Chemicals:\u003c\/strong\u003e None\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eSimple, No-Power Design\u003c\/strong\u003e — purely mechanical magnetic reed switch; no external power needed\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eDurable PP Construction\u003c\/strong\u003e — resistant to a wide range of liquids including water and mild chemicals\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eAdjustable Switching Direction\u003c\/strong\u003e — flip the float to reverse open\/close action\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eCompact \u0026amp; Long-Lasting\u003c\/strong\u003e — smaller than standard mechanical switches with extended service life\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eWide Application Range\u003c\/strong\u003e — suitable for any compatible liquid within the rated temperature and voltage range\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eEasy Installation\u003c\/strong\u003e — horizontal mount, straightforward wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWide Industry Applications\u003c\/h3\u003e\n\u003cp\u003eThis float switch is used across many industries and setups: shipbuilding, power generation equipment, petrochemical plants, food processing, water treatment facilities, dyeing and finishing machinery, hydraulic systems, home water tanks, and more.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMade in Mainland China.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch3\u003eYou May Also Like\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/air-compressor-pressure-gauge-0-10-0-12-0-25-bar-hydraulic-diy\"\u003eAir Compressor Pressure Gauge 0-10\/0-12\/0-25 Bar | DIY Tool\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/electromagnetic-induction-tester-coil-motherboard-fault-detector\"\u003eElectromagnetic Induction Tester – Coil \u0026amp; Circuit Fault Detector\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/balashov-2500w-handheld-steam-cleaner-kitchen-car-home\"\u003eBALASHOV 2500W Handheld Steam Cleaner – Kitchen, Car \u0026amp; Home\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.osha.gov\/hand-power-tools\" target=\"_blank\" rel=\"noopener\"\u003eOSHA guidance on hand and power tools\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What liquid types is this PP float switch compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The polypropylene (PP) float switch is compatible with water, mild chemicals, and a wide range of non-aggressive liquids. As long as the liquid is within the rated temperature range (-10°C to +60°C) and does not chemically degrade PP plastic, this float switch can be used effectively.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I reverse the switching action of the horizontal float switch?\u003c\/h4\u003e\n\u003cp\u003eA: Simply remove the retaining clamp and flip the float ball downward. This reverses the open\/close action so the switch triggers when the liquid level drops rather than rises — or vice versa — giving you flexible control over your application.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this float switch with a pump or solenoid valve?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The float switch can be wired into a control circuit to activate or deactivate a pump, solenoid valve, or alarm when a set liquid level is reached. Ensure the load stays within the rated limits: max 0.5A switching current and 220V switching voltage.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What liquid types is this PP float switch compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The polypropylene (PP) float switch is compatible with water, mild chemicals, and a wide range of non-aggressive liquids.
