Electronic Pressure and Vacuum Switches for Compressed Air
Designed specifically for air systems, these switches send signals to your programmable logic controller (PLC) to activate controls or alarms when your system reaches a set pressure or vacuum. All meet at least one American, Canadian, or European safety standard.
Monitor pressure, setpoint, and reset point on the digital display. Use the display’s buttons to change your settings. These switches have an adjustable reset point (also called adjustable deadband or differential), so you can control the amount of pressure or vacuum change before the switch resets. Choose anywhere within the setpoint range for your reset point.
Add a panel-mounting bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Dual-Setpoint Electronic Pressure and Vacuum Switches for Compressed Air
With two setpoints, these switches trigger different actions in your air system by sending signals to a programmable logic controller (PLC) when they reach one of their set pressures or vacuums. For example, they can activate one light when a system is pressurized and another when it’s under vacuum. They have an adjustable reset, so you can control the amount of pressure change before the switch resets. This pressure difference is also called deadband or differential. Choose a reset point anywhere within the setpoint range.
Easily monitor your pressure or vacuum setpoint on the digital display. Use its buttons to adjust the settings and setpoint.
These switches are rated IP65 to seal out dust and water from light rinses. They’re CE marked, UL and C-UL recognized components, and CSA certified to meet American, Canadian, and European safety standards.
Add a panel-mounting bracket (sold separately) to mount switches to a control panel for easy viewing and adjusting.
