Daikin-McQuay 0130F00505 SPST Furnace Draft Inducer Air Pressure Switch -0.70" WC

The Daikin-McQuay 0130F00505 is an OEM single-pole single-throw (SPST) furnace air pressure switch rated at -0.70 inches water column (-0.70" WC). This safety switch monitors the negative pressure generated by the draft inducer motor during furnace operation, verifying that proper airflow and venting conditions are present before allowing ignition to proceed.

If the inducer motor fails to reach the correct operating speed or a venting obstruction is detected, the pressure switch interrupts the ignition sequence, protecting the heat exchanger and preventing the release of combustion gases into the living space.
