Float Switch | Tank & Pool Water Level Sensor | PP Plastic Ball

This horizontal float switch is a straightforward liquid level sensor for your tank or pool project. It mounts on the side of a container to detect a specific high or low water level. As the liquid rises or falls, the float pivots and activates an internal switch. Features and Benefits - Side-mounted horizontal design - Installs through the wall of a tank, which is useful when top access is limited or a vertical switch won't fit. - Made from corrosion-resistant PP plastic - Safely works in water, nutrient solutions, and other mild liquids, making it a good fit for hydroponics. - Simple magnetic reed switch - Provides a reliable on/off signal for a pump, valve, or alarm with its 10W power rating. - Reversible float for custom logic - Lets you set the switch to be normally open or normally closed just by removing a clip and flipping the float. Applications - Automating pumps to refill a water tank or empty a sump pit. - Triggering high or low-level alarms in aquariums and fish tanks. - Controlling water levels for a DIY pool auto-fill system or hydroponics setup. What It Is A float switch is a type of liquid level sensor designed to detect and monitor water levels in tanks and pools. This particular model features a PP Plastic ball, which is the buoyant component that moves with the liquid level. Inside the float, a physical switch, often a reed switch, is activated or deactivated by the movement of the float. This mechanism allows the float switch to act as an automated switch, signalling when a predetermined water level has been reached. Key Uses & Applications This liquid level float switch is suitable for a variety of applications where automated water level detection is required. Its primary use is in tanks and pools to sense when water levels change. The horizontal mounting type makes it ideal for installations where side-entry sensing is needed. As a sensor type, it can be integrated into systems that require an internal switch or relay to trigger other devices, such as pumps or alarms, based on water levels. Compatibility with Arduino systems expands its use in custom automation projects. How to Choose When selecting a float switch, consider the material and mounting type. This specific model is made from PP Plastic, which is suitable for many water-based applications, and features a horizontal mounting design. For systems requiring integration, note its compatibility with Arduino. The sensor type, a liquid level float switch, indicates its function in detecting water levels. Ensure the physical switch mechanism and any associated internal switch or relay meet the requirements of your project for accurate and reliable water level monitoring.
