Designed for high-pressure applications, these switches electrically activate automated controls or alarms when a set pressure is reached. They are often used in pump and hydraulic power applications. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC). Switches are rated NEMA 1 for indoor use.

Sensitive to low pressures, these switches electrically activate automated controls or alarms when a set pressure is reached. They are often used in heating and ventilation systems. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC). Switches are rated NEMA 1 for indoor use.

Change your setpoint with a twist of the outer ring. These switches are rated NEMA 4 for protection from dirt and washdowns. They electrically activate automated controls or alarms when a set pressure is reached. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

Switches have a digital display for easy monitoring at the source of your application. Set the LED to show your pressure, setpoint, or reset point. Switches electrically activate automated controls or alarms when a set pressure is reached. They are rated NEMA 4X for protection from dirt, washdowns, and corrosion. They are single pole, double throw (SPDT), so they switch one circuit on and off. They can be wired normally open (NO) or normally closed (NC).

At only 1 1/4" wide, these compact switches are a good fit for cramped spaces. They are often used in pump and hydraulic power applications. Switches electrically activate automated controls or alarms when a set pressure is reached. They are rated NEMA 4 for protection from dirt and washdowns. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

Not only are these switches sensitive to high pressures, they have a digital display for easy monitoring at the source of your application. Set the LED to show your pressure, setpoint, or reset point. The difference between setpoint and reset point is adjustable so you can set it anywhere within the setpoint range. Switches electrically activate automated controls or alarms when a set pressure is reached. They are rated NEMA 4X for protection from dirt, washdowns, and corrosion. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

These switches are rated NEMA 4 or 4X for protection from dirt and washdowns. Sensitive to low pressures, they electrically activate automated controls or alarms when a set pressure is reached. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

Often used with hydraulic presses, compactors, and machine tools, these switches are rated NEMA 13 for indoor protection from dirt and oil/coolant spraying. Switches electrically activate automated controls or alarms when a set pressure is reached. They are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

Like other 3-A certified sanitary pressure switches, these switches trigger controls and alarms when food-processing, pharmaceutical, and biotech lines reach a set pressure, but they also have a sanitary adjustable setpoint ring that you twist to make quick changes. They have a sleeve to shield their internal parts from water and other contaminants that could produce bacteria. To further prevent bacteria from growing, as well as make cleaning easier, the surfaces of these switches are polished and their seams are continuously welded. Made of 316 stainless steel, they stand up to harsh cleaners and sanitizers without rusting. They’re rated IP67 and NEMA 6, meaning they’re protected against dust, dirt, corrosion, and temporary submersion. All have a flange that connects to sanitary quick-clamp fittings (also known as tri-clamp fittings); they’re easy to connect and remove from your line.

Their quick-clamp end has a 316 stainless steel diaphragm that protects these switches from corrosive substances and covers threads to keep bacteria from growing in them. The diaphragm is filled with 99.5% pure USP food-grade glycerin, reducing the risk of contamination if the diaphragm fails. To access the material certificate with traceable lot number and test report, the diaphragm is laser etched with its serial number—the etching leaves minimal room for bacteria to grow.

These switches are single pole, double throw (SPDT), so they switch one circuit on and off. Wire them normally open (NO) or normally closed (NC).
