Arrow Hart and Hegeman 1R363 Sump Pump Float Switch

The Arrow Hart and Hegeman 1R363 Sump Pump Float Switch is a float-operated device that automatically activates a sump pump as water level rises in a sump basin and deactivates it when the level falls, enabling hands-free operation and helping prevent basement overflows. It is intended for use in residential and light commercial sump pump installations to provide level-based control without manual operation, supporting reliable water removal in basements, crawl spaces, garages, and other low-lying areas prone to water intrusion. As part of the Arrow Hart family, the 1R363 is a switch component designed for integration with standard sump pump wiring in damp environments, aligning with the company’s emphasis on safety, durability, and compatibility with common electrical fittings and pump configurations. The model designation 1R363 identifies this specific float switch within Arrow Hart and Hegeman’s line of sump-pump control components, providing a defined reference for installers seeking replacement parts or coordinating with compatible pumps, housings, and control panels in service-entry basements and utility rooms.
