Before you choose
The Pressure switch is a Switch that acts according to a Pressure: in the Boilers watertight, the airtight one checks that the Flue fan evacuates the fumes before ignition; others monitor the Pressure from the water.
To choose it, compare the reference and, if read, the Pressure values of the label; check the Ports number and the position of the terminals. Two Pressure switches equals on the outside can work to different Pressures.
What data identify a Pressure switch?
The full reference and, when readable, Pressure signs on the label allow you to contrast variants. Also check the Ports and connections. Do not choose a Part just by the shape of your housing.
What do the Pressure switch label numbers indicate?
In addition to the reference, they usually indicate the Pressuress to which they connect and disconnect, often in pascals (Pa) or milibares (mbar). Compare them with your Part; if they are not read, do not give them equals.
