The Grundfos Float Switch is a simple, reliable level-sensing accessory designed for use with SQFlex pump systems and storage tank applications. When paired with the CU200 controller or IO101 Switch Box, it automates pump start and stop functions based on water level — preventing tank overflow and protecting the pump against dry-running in unattended or remote installations. Built for durability in wet environments, it is a straightforward, low-maintenance solution for hands-free water level management.
