Pressure Switches

We offer and stock a wide variety of pressure switches, both mechanical and electronic pressure switches. Pressure switches are a great method for pump control, High and Low alarm conditions, and any simple ON/OFF pressure condition. Pressure switches come in a multitude of options, including General Purpose and Explosion Proof Enclosures, AC and DC rated switching mechanisms, Bourdon Tube, Piston and Diaphragm Actuated, Fixed Deaband and Adjustable Deadband, numerous agency approvals, and many, many more options and configurations. Why worry about trying to decipher which options are necessary or not, when you could simply call Colonial Instruments, and have one of our skilled associates help you select and specify the correct switch for your application? We can also set switches in house and verify set point, as well as, provide SI or NIST traceable calibration, when necessary.
