Pump Switches & High Water Alarms

Pump switches and high-water alarms that activate bilge pumps or alert crew when water levels rise beyond safe limits. High-water alarms provide a separate warning when bilge level rises beyond normal pump operation, while control switches automate pumps. Design the alarm so a failed pump or primary switch does not also disable the warning circuit. Compare sensor technology, switching current, supply voltage, audible output and manual override arrangement.
