Campbell L100208653 Flow Switch Nema 1 Brass Bushing

Product Description

The CAMPBELL L100208653 is a NEMA 1 flow switch with paddle and brass bushing, designed for use in hydronic heating and boiler systems. The flow switch monitors liquid movement through a pipe and signals the system to start or stop based on detected flow. When flow is present, the paddle actuates the internal switch mechanism, allowing the connected equipment to energize. When flow stops, the switch opens to shut down the system. This type of control is a critical safety and operational component in hot water boiler and heating system installations, typically serviced by licensed plumbers and HVAC technicians.

This flow switch is suited for residential and light commercial hydronic applications where reliable flow detection is required. It installs in a pipe fitting using the brass bushing and relies on the included paddle to sense water movement. The NEMA 1 enclosure rating makes it appropriate for indoor, dry-location installations. It is commonly installed on the supply or return piping of boiler systems to protect equipment from dry-fire conditions or low-flow faults.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic systems. Shut off the boiler and relieve system pressure before removing or installing any flow switch. Ensure the paddle size is appropriate for the pipe diameter prior to installation. Follow all applicable local plumbing and mechanical codes during installation and wiring of the switch.
