Pressure Switches | Air Suspension Parts
Pressure switches are an integral part of every air suspension system. They are small electronic devices that monitor the air pressure inside of the suspension air tank. Without them, your system would not be able to accurately fill or bleed the air reserve tank.
How Do Air Suspension Pressure Switches Work?
The pressure switch in an air suspension system has an electronic sensor that measures the air pressure in your tank. Using this information, the switch instructs the compressor on when to run and when to shut off to maintain the optimal tank pressure.
In most cases, the switch turns the compressor on when pressure goes under 110 PSI. It typically shuts the compressor off once internal pressure reaches 145 PSI.
How to Find the Right Pressure Switch For Your Vehicle
Different vehicles have different needs when it comes to the air pressure in their suspension systems. In general, the heavier your vehicle is or the heavier load you need to haul, the higher PSI capacity you’ll want.
Pressure switches typically range from around 120 PSI to 500 PSI for the OFF switch. When it comes to the ON switch, they tend to range from around 50 to 150 PSI.
Finding the right pressure switch for your vehicle can be somewhat of a balancing act. While a higher PSI means more support, the increased pressure also increases the likelihood of a leak. Such leaks can lead to early failure of your air suspension components.
