Horizontal Float Ball Water Level Sensor Switch for Water Tank

The Float Ball Water Level Sensor Switch detects rising and falling water levels by tilting a float (a buoyant ball that moves with the water surface) mounted on a horizontal axis. The water float sensor triggers at a 70-degree opening angle, making it responsive to small water level changes inside tanks, sumps, and reservoirs.

The float water level sensor switch carries a breakdown voltage (the maximum voltage before the switch fails electrically) of 220V DC and handles up to 1A of current. One non-obvious detail — this is a latching mechanical switch, meaning the float must travel the full 70-degree arc before the circuit changes state. Polling it with a microcontroller without a debounce delay can produce false triggers. The honest limitation is that hard water deposits can gradually coat the float and reduce its buoyancy over time.

The horizontal water float sensor suits students, plumbers, and makers building tank overflow alerts or pump control circuits. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
