A vertical float switch detects liquid level by allowing a magnetic stainless steel float ball to rise and fall along a vertical stem or rod. As the liquid level changes, the float's magnet triggers an internal reed switch, activating pumps, alarms, or valves to control filling, draining, or overflow protection in tanks and vessels.
