Armstrong Furnace R100684-04 Pressure Switch The inclusion of a robustThe Armstrong Furnace R100684 04 Pressure Switch is a critical safety component engineered for precise inducer motor verification and flue gas management. This OEM replacement part is factory calibrated to a . 65"wc set point, ensuring the combustion blower is generating the necessary static pressure before allowing the ignition sequence to proceed. As a SPST (Single Pole Single Throw) switch, it provides a reliable normally open circuit that closes
