I recently tested a pressure switch for my car that I was extremely happy with .As a result of my tests I determined that this switch was the best way to monitor oil, fuel, and transmission pressure. The switch was easy to install and provided consistent and reliable data to my gauges. The only con was that it was a bit more expensive than other options on the market, but the quality made it worthwhile. Overall, if you're looking for a top-quality pressure solution for your car, this switch is a great choice..
