Field Controls 602602002 Pressure Switch

The Field Controls 602602002 Pressure Switch is a critical safety component designed for precise draft induction monitoring in HVAC systems. This SPST pressure switch is factory-calibrated to a .8" WC set point, ensuring the venting system maintains proper static pressure before allowing ignition. As the direct replacement for 46246100, this component is engineered to meet the exact specifications of legacy Field Controls units, providing a seamless drop-in solution for service contractors. The switch utilizes high-quality silicone diaphragms and robust electrical contacts to handle the cycling demands of residential and commercial power venters. By monitoring negative pressure within the flue or collector box, it prevents operation during venting blockages or motor failure. Its compact design allows for versatile mounting in tight cabinets, while the standard spade terminals simplify HVAC wiring and installation. This technical component is essential for maintaining equipment reliability and code compliance in forced-draft applications.

• Precise .8" WC Calibration: Ensures accurate differential pressure sensing for safety circuit integration.
• Universal Compatibility: Serves as the designated OEM replacement part for discontinued model 46246100.
• Reliable SPST Logic: Simplified Single Pole Single Throw configuration for standard normally open operation.
• Durable Construction: Built to withstand high-temperature environments near draft inducer motors.
• Field Reliability: Reduces call-backs by providing consistent pressure switch trip points.

Is the 602602002 compatible with high-efficiency furnaces?
This switch is specifically calibrated for .8" WC and is primarily used with Field Controls power venting systems. Always verify the pressure switch rating on your existing part’s label before installation.

Can this replace a switch with a different WC rating?
No, HVAC pressure switches must match the specific water column inches required by the equipment manufacturer to ensure the system fails-safe under improper venting conditions.

What are the symptoms of a failing Field Controls pressure switch?
Common indicators include the inducer motor running without the burners igniting or the system displaying pressure switch lockout codes due to stuck contacts or a ruptured diaphragm.
