The backbone of our operation at Pressure Switches, Inc. is a modern, well equipped CNC Manufacturing Facility here in the south Louisiana. The design of the PSI switches was based upon utilizing this extensive line of "State-of-the-Art" equipment, located in a modern, spacious facility, with close proximity to surface and air transportation (with overnight delivery if required).

We have over thirty years of designing and manufacturing in the pressure switch field. We feel the manufacturing and performance of our switches equals or exceeds those "Industry Standards"

All series are field adjustable, with an internal slotted adjustment wheel for use with a screwdriver tip, in a separate area away from the electrical switch and wiring. Our aim has been simplicity of design, based upon sound engineering principles, in an extremely clean, rugged "package", yet sensitive and reliable in operation. BACK-TO-BASIC is what we have attempted to accomplish. All models in all series have extremely sturdy enclosures that are precision machined from aluminum extrusions. We use stainless steel fasteners. Internal parts are either stainless steel or anodized aluminum. (NO aluminum diecastings or cadmium plated steel is used in any of the fabricated parts.) All markings including the range scales are laser engraved for long term readability. Pressure Switches Inc. / aka PSI is the only full line pressure switch manufactured in the deep South. We are now in our second decade of providing dedicated service to our customers.
