DC 220V Aquarium Float Switch – Right Angle Water Level Sensor
DC 220V Aquarium Float Switch – Right Angle Water Level Sensor
DC 220V Aquarium Float Switch – Right Angle Water Level Sensor
Keep your aquarium, water tank, or reservoir perfectly regulated with this compact and reliable DC/AC 220V Float Switch Water Level Sensor. Engineered for precision liquid level detection, this right-angle float switch automatically triggers open or closed circuits as water rises or falls — making it ideal for pumps, alarms, and automated water management systems.
Key Features
- High-Quality Plastic Construction – Durable, corrosion-resistant body built for long-term use in wet environments.
- Wide Voltage Compatibility – Works with both AC/DC 0–110V and AC/DC 0–220V circuits for flexible installation.
- Reliable Magnetic Reed Switch Mechanism – The magnetic float rises and falls with the liquid level, triggering the internal reed switch for accurate, contact-based control.
- Compact Right-Angle Design – Small footprint allows easy installation in tight spaces such as tanks, sumps, and aquarium cabinets.
- Wide Operating Temperature Range – Rated for -30°C to 125°C, suitable for a broad range of environments.
- Supports Multi-Point & Remote Control – Easily integrate into multi-sensor or remote-monitoring setups.
- Simple Operation – No complex programming required; plug-and-play liquid level automation.

How It Works
The float switch is composed of a magnetic reed switch housed in a sealed non-magnetic tube, and a floating ball containing magnetic material. As the liquid level rises or falls, the magnetic float moves along the tube. When the float approaches the reed switch, it closes the circuit (ON); when it moves away, the circuit opens (OFF). This simple yet effective mechanism ensures dependable liquid level control and indication without any external power for the sensing element.
Common Applications
- Aquariums and fish tanks
- Water storage tanks and reservoirs

Frequently Asked Questions
Q: What voltage is this aquarium float switch compatible with?
A: This float switch supports both low and high voltage circuits — it operates at 0–110V DC/AC (0.5A switching current, 10W) and 0–220V DC/AC (1A switching current, 50W). For everyday aquarium use, the 0–110V range is recommended for safety.
Q: How does the right-angle float switch work in an aquarium or water tank?
A: The float switch uses a magnetic reed switch mechanism. As water levels rise, the magnetic float moves up toward the reed switch, closing the circuit and activating connected devices such as pumps or alarms. As the water drops, the float descends and the circuit opens, turning the device off — providing fully automatic water level control.
Q: Is this float switch suitable for outdoor or high-temperature environments?
A: Yes. With a working temperature range of -30°C to 125°C, this float switch is suitable for use in a wide variety of environments, including outdoor installations and systems that may experience temperature extremes.
Q: Can this float switch be used in a multi-point or remote control setup?
A: Absolutely. This sensor conveniently supports multi-point configurations and remote control implementations, making it easy to integrate into automated or monitored water management systems.
