A magnetic float switch uses a buoyant float containing an internal magnet that rises or falls with liquid levels. As the float moves, the magnet triggers a reed switch or sensor in the stem, opening or closing an electrical circuit to activate pumps, alarms, or shutoff valves at a preset liquid level.
