The air compressor pressure switch helps to measure the pressure inside your air tank and then is used to shut off your compressor when your tank reaches a set air pressure. The air compressor pressure switch will also help your compressor maintain the proper pressure level as you go about your work. The switch can turn on your compressor when tank air pressure levels drop and more air is needed. This makes your air compressor pressure switch a part that gets used often, so it may wear down sooner than others. You’ll want to keep it properly maintained and fix it, or replace it when any problems arise. Air Compressors Plus stocks a variety of pressure switches so when the time comes to replace your switch, give us a call or stop by.
