Fixed Setpoint Pressure Switches
 |  |
Screw-Terminal Wire Connection | Wire Lead Connection |
Prevent changes to the set pressure that activates equipment—these switches come ready to use at your preferred setpoint. Often used to turn equipment on and off when a set pressure is reached, they can also be used to activate automated controls or signal alarms. They’re single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed).
NEMA 4 and 13 rated, they seal out dirt, oil, and water from washdowns. These switches are also UL and C-UL recognized components and are CE marked, so they meet American, Canadian, and European safety standards.

Pressure Switches
 |
Style D |
The traditional pressure switch. These power equipment, activate controls or alarms, or kick-off other actions when they reach a set pressure. Larger than compact pressure switches, they're easier to wire. These switches are 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).
Pressure Switches with Cover
|
Style D |
Switches with a cover protect against impact and keep dust off the switch.
NEMA 13 Enclosure Rating—NEMA 13 rated switches can be used in dirty, damp, and oily areas.

Adjustable-Reset Pressure Switches with Digital Display
 |
Kick off automated controls, signal alarms, or activate equipment based on pressure changes while checking the pressure, setpoint, and reset point on the display. The adjustable reset point lets you control the amount of pressure change, also known as deadband and differential, before the switch resets. Adjust it anywhere within the setpoint range. Turn the external adjustment knob by hand to set pressure quickly. These are 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).
To power the display, these switches need a separate electrical input from the one used for switching.
These switches are IP and NEMA rated, so they’re dust tight and protected against water from washdowns and weather, as well as sprays of oil and coolant.

Differential Pressure Switches for Air
 |
Connects to Tube |
Often used with ovens, dryers, and HVAC systems, these switches detect small differences in air pressure to indicate a filter is clogged or help you maintain a certain air pressure. When the differential pressure reaches your setpoint, these switches can turn equipment on and off, activate automated controls, or signal alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on or from on to off. All meet at least one safety standard.
When measuring pressure in ductwork, pair them with a static pressure probe.
IP54 Enclosure Rating—Switches rated IP54 protect against dust and splashing water.
NEMA 13 Enclosure Rating— NEMA 13 rated switches can be used in dirty, wet, and oily areas.
