Weatherproof Pressure Switches

SOR weatherproof pressure switches are designed to be weather tight for external use. They are built to stand up to the rigors of the environment and provide long-lasting and dependable service. Diaphragm type switches are recommended for most process applications while pivot seal type weatherproof pressure switches perform best in fluid power (hydraulic) applications.
