DIY – Air Pressure Switch

There is no secret that many Airbrushists love to use DIY stuff as it comes much cheaper and they can spend more money for a good airbrush gun. Home-made compressor build of old refrigerator compressor with an old fire extinguisher tank or even with coke bottle tank and car fuel filters in it isn’t unusual anymore. Even manometer isn’t a problem to get. The biggest problem is to find an air pressure switch or set it up so it will work properly. I have found out a temporary solution which can be made in few minutes untill you get the real one.
