The Vertical Float Switch is a water-level sensor that mounts inside a tank and rises or falls with the water surface. As the float moves with the level, it makes or breaks contact so a connected pump or controller knows when the tank is full or empty. It is a simple, reliable way to automate filling and draining for home water tanks, garden irrigation reservoirs, hydroponic systems, and small farm or project setups.
Key features
- Vertical-mount float design that tracks the water surface as it rises and falls.
- Senses tank level to trigger automatic pump start or stop.
- Simple installation inside most common water tanks and reservoirs.
- Helps prevent dry-running of pumps and overflow of tanks.
- Compact build suited to everyday home and garden use.
Typical uses
- Automatic level control for rooftop and ground water tanks.
- Refilling irrigation reservoirs for drip and sprinkler systems.
- Top-up and drain control in hydroponic and nursery tanks.
- Pump protection on small farm and project water systems.
How to choose / tips
- Confirm the switch matches your pump or controller wiring and voltage before installing.
- Mount it vertically with clear space so the float can move freely.
- Keep the float area free of debris for consistent sensing.
- Pair it with a suitable relay or controller for fully automatic operation.
