This is one of the most critical components of any air system and is required to run a air compressor. A pressure switch regulates the compressor to turn on and off automatically when you are high and low pressure.

Even if you intend to use a manual switch with your pump, a pressure switch insures that you won't over-pressurize your system potentially damaging your equipment.
