Adjustable-Reset Vacuum Switches
Control the amount of vacuum change between when these switches activate and deactivate by adjusting when they reset. Also known as adjustable deadband and differential switches, you can set the reset point anywhere within the setpoint range. Use them to power equipment, signal controls, or trigger alarms when they reach the set vacuum. They’re single pole, double throw (SPDT) and can either turn one circuit from off to on (normally open) or on to off (normally closed). All meet safety standards.
All protect against some corrosion. NEMA 4X and IP66 rated switches can be used in dirty and wet areas exposed to washdowns. NEMA 4X switches also stand up to weather and have increased protection against corrosion, similar to 304 stainless steel.

Pressure and Vacuum Switches
Because these switches work with both positive and negative (vacuum) pressures, you can use them in applications that span both. For example, these switches can turn on a light when they reach the setpoint to indicate which pressure is flowing. They’re also often used to trigger automated controls and activate alarms. These switches are single pole, double throw (SPDT) and can either turn one circuit from off to on (normally open) or from on to off (normally closed).
NEMA 4X and IP66 rated, they’re dust tight and protected from washdowns and corrosion. All are UL and C-UL listed, CSA and CSA-US certified, and CE marked, so they meet U.S., Canadian, and European safety standards.
