Pressure Switch

Pressure switches enable your air conditioning system to react appropriately given certain pressures being obtained within your system. The are used most commonly to shut your system down if pressures are too low or too high, and are also used to allow condenser fans to cycle, running only when they are required.

In many modern vehicles, pressure switches have been replaced by pressure transducers, which serve a similar purpose, but in a much more advanced way that is more valuable to modern, computer-controlled A/C systems.

Pressure switch failure can lead to an inoperable system, or worse still, major component failure. It is essential that the operation of your pressure switches is checked by a competent air conditioning specialist, such as those found on this site.
