Hazardous Location Pressure Switches


Style A	Style B

Built with an explosion-proof enclosure to meet NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive liquids, dust, and gas are present. When they reach the set pressure, they power equipment, signal controls, or trigger alarms. They’re single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). In addition to being UL listed and CSA certified, these switches are CE marked, so they also meet European safety standards.

All switches are IP and NEMA rated for use outdoors and protection from some corrosion, dust, and spraying water.

Style A	Style B

IP67 Enclosure Rating and NEMA 4X Enclosure Rating—IP67 and NEMA 4X rated switches seal out water from temporary submersion and have increased protection against corrosion, similar to 304 stainless steel.

Compact Pressure Switches

With a round body that’s at least one-third thinner than traditional pressure switches, these fit in tight, cramped spaces. They’re often built into pumps and hydraulic systems with limited space in order to turn equipment on and off, activate automated controls, or signal alarms when they reach a set pressure. These switches are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). They also meet at least one American, Canadian, or European safety standard.

Wire Lead Connection

Internal Adjustment—Switches with an internal setpoint adjustment have a sliding cover to prevent accidental setting changes.

IP67 Enclosure Rating and NEMA 6 Enclosure Rating—IP67 and NEMA 6 rated switches seal out dust and water from washdowns and temporary submersion.
