PSI was founded by Warren R. Davis in
1989, a graduate of UCLA, and a registered professional engineer
from the state of California. Prior to starting PSI, Mr. Davis had
over 30 years of extensive experience in all phases of engineering
and manufacturing of pressure switches for both the airborne and
industrial markets. All of the pressure switches manufactured by PSI
were designed by Mr. Davis, noting that all models have third-party
approvals, i.e., UL or CSA as applicable.
backbone of our operation at Pressure Switches, Inc. is a modern, well

of "State-of-the-Art" equipment, located in a modern
facility with close proximity to surface and air transportation (with
overnight delivery if required).
We have over 50 years of designing
and manufacturing in the pressure switch field. We feel the manufacturing
and performance of our switches equals or exceeds "Industry
