Trane SWT2535 - OEM Furnace Air Pressure Switch 2.25"

# Switch

Key Features:

Built with quality in mind, this new pressure switch is made of bakelite and designed to operate in temperatures ranging from -40° to 250° Fahrenheit.

The switch is something that we don't really complain about as a customer but if it breaks down or needs to be replaced we certainly notice. It's also one of those things that is not easily replaced by the home owner and most will call an HVAC contractor if anything goes wrong. This particular unit has been discontinued but there are still a lot of older homes out there with this same furnace and they will eventually need to be replaced. It's also something that if you don't make any changes to your home heating system it's something you may never even have to think about.
