Horizontal Float Sensor Switch | Side Mount Water Level Controller
Horizontal Float Sensor Switch | Side Mount Water Level Controller
Horizontal Float Sensor Switch — Precise Liquid Level Control for Tanks, Aquariums & More
Keep your water systems running smoothly and automatically with this compact horizontal float sensor switch. Designed for side-mount installation, this high-precision liquid level controller detects water level changes and triggers your pump or valve automatically — no guesswork, no manual monitoring required.
Built from food-grade polypropylene (PP) with a reed tube sensing mechanism and silicone sealing gasket, it's engineered for reliable, long-lasting performance in aquariums, water purifiers, household storage tanks, and small liquid equipment setups. Made in Mainland China.
Key Features
- Corrosion-Resistant PP Housing: Food-grade polypropylene construction resists water, weak acids, and alkalis — will not rust or contaminate your liquid, making it ideal for drinking water systems and aquariums.
- High-Precision Reed Tube Sensing: Fast induction response ensures accurate on/off switching with minimal water level control error, improving the operational stability of your connected equipment.
- Smooth Duckbill Float Structure: Integrated engineering plastic float is highly sensitive to buoyancy changes, moves without jamming, and accurately triggers the switch as water levels fluctuate — greatly reducing false triggers.
- Waterproof Sealed Design: Food-grade silicone gasket and fully encapsulated wiring provide excellent waterproof and moisture-proof protection, extending service life in humid environments.
- 6 Model Options (A–F): Choose from six different specifications to match your tank type and mounting requirements — no additional modification needed, easy and fast to install.

Frequently Asked Questions
Q: What types of tanks is this horizontal float sensor switch compatible with?
A: This side-mount liquid level float switch is compatible with a wide range of small tanks and equipment, including aquarium tanks, household water storage tanks, water purifiers, and small liquid storage systems. With 6 available models (A–F) covering body lengths from 5 cm to 9 cm, it fits most standard mounting holes without any modification.
Q: Is this float switch safe to use in drinking water or aquarium systems?
A: Yes. The switch is constructed from food-grade polypropylene (PP) and sealed with a food-grade silicone gasket, making it safe for use in drinking water purifiers and aquarium environments. It will not rust or leach contaminants into the liquid.
Q: How does the reed tube in this water level sensor work?
A: The reed tube is a magnetically actuated switch housed inside the sensor body. As water rises or falls, the buoyant duckbill float moves and the magnet within it activates or deactivates the reed tube, creating a fast and accurate on/off signal to control your pump or valve automatically.
Q: Is this float sensor switch waterproof?
A: Yes. The design features fully encapsulated wiring and a food-grade silicone sealing gasket that prevents water vapor from penetrating internal components, ensuring reliable, long-lasting performance in wet and humid environments.
