Custom Pressure Switches

Customized switches for challenging applications

Custom Pressure Switches

In addition to commercial off-the-shelf (COTS) models, we design, manufacture and deliver custom engineered pressure switches for a range of challenging industries, including oil and gas, medical, transportation, food processing, military, commercial aerospace and more. Choose from gauge, absolute and differential switches—all of which are built to thrive in severe environments. You can also customize your switch with your own wire, cable, seal materials and weather-proof connectors.
