Vertical Float Switch — 2 pcs (PP body, M10 thread, 77 mm length, 40 cm cable) What it does Detects liquid level changes and closes or opens a circuit to activate pumps, valves, or alarms. Prevents unwanted overflow and protects pumps from dry running in both freshwater and saltwater setups. Key benefits — why you need it Protects equipment: Automatically stops pumps or triggers alarms to avoid damage from dry running or overflow. Reliable sensing: Stable signal transmission for consistent level detection in tanks and systems. Spaceefficient: Compact 77 mm body and M10 threaded mounting fit tight spaces and common fittings. Longlasting material: Polypropylene (PP) construction resists corrosion in aquarium, pool, and general water applications. Main features Quantity: 2 pieces per package. Body material: PP (polypropylene) for chemical and water resistance. Mounting: M10 threaded fitting for standard installations. Size: 77 mm body length; compact for confined installations. Cable: Includes 40 cm cable for easy connection. Operation: Vertical float switch design for clear ON/OFF level detection. Environment: Suitable for freshwater and saltwater use. Electrical limits: Maximum switching voltage 110 V DC, maximum switching current 0.5 A. Temperature range: 10 to +60 °C. Typical function: Activates pumps or alarms to prevent overflow and dry running; provides a simple, binary level signal. Compatibility and installation General compatibility with water towers, storage tanks, aquariums, pools, gardening and irrigation systems, and similar liquid level applications. Compact design and M10 thread make installation straightforward in standard threaded ports and limitedspace locations. Practical use scenarios Aquarium or fish tank: Maintain a safe water level by automatically refilling or stopping off pumps to protect fish and equipment. Pump protection for ponds or pools: Shut off a pump or trigger an alarm when water falls below a set point to avoid dry running and pump damage. Irrigation and storage tanks: Monitor reservoir levels to automate refill cycles or prevent overflow in gardening and smallscale water storage systems. Specifications (summary) Pack: 2 pcs Material: PP (polypropylene) Mount: M10 thread Body length: 77 mm Cable length: 40 cm Switching voltage: up to 110 V DC Switching current: up to 0.5 A Temperature range: 10 to +60 °C Simple, reliable level sensing for compact installations where pump protection and overflow prevention are required.
