Pressure Switches

The Pressure Switches category covers electromechanical and solid-state devices used to monitor, control, and signal based on system pressure conditions across industrial automation applications. Controls engineers, machine builders, and panel shop integrators rely on these devices for hydraulic systems, pneumatic circuits, compressed air monitoring, and process fluid control. Common product types include electromechanical pressure switches with adjustable setpoints for general-purpose switching, solid-state pressure sensors offering discrete or analog output with no moving parts for higher cycle-life applications, and replacement enclosures and accessories such as conduit adapters and cable assemblies for field service and maintenance. Available configurations span gauge, absolute, and vacuum pressure ranges — from deep vacuum (inHg) to high positive pressure — with 1/4 NPT and other common process connections. Key selection considerations include pressure range, output type (NPN/PNP, analog 4–20 mA), enclosure rating, and display requirements.
