Pressure Instruments | pressure switch | mechanical switch

A pressure switch is a control device that senses changes in pressure and mechanically opens and closes an electrical circuit at a pre-determined point. Unlike other pressure instruments like pressure gauges and pressure sensors that measure and monitor pressure, switches are a bit more complicated. Ashcroft is an industry leader in pressure measurement instrumentation and created this article to provide a basic foundation of information about switches for the industry novice. Read on to learn about the different types of pressure switches, common applications, how they operate, key terms, switch accuracy, activation methods and more. When you’re done reading, you will also find additional resources about switches that may interest you.
