Schneider Electric (Square D) 9037EW9 Float Switch

The Schneider Electric (Square D) 9037EW9 Float Switch used to detect fluid height in different systems. The Part contains a buoyant float element that moves up and down with liquid changes to trigger electrical snap-action contacts. The switch operation enables control of pumps and valves and alarms to maintain fluid management. The switch operates frequently within HVAC systems condensate drainage systems to protect equipment from water damage. The part operates reliably to prevent floods which in turn decreases maintenance requirements as well as system downtime. The basic operation of this system enables efficient level monitoring which improves system performance and extends operational life.
