Barksdale Dia - Seal Piston Switches

E1S, E1H Series Pressure or Vacuum - Econ-O-trol

The E1S and E1H Econ-O-Trol Pressure Switches deliver powerful performance in a compact, economical package. Available in corrosion resistant thermoplastic or die cast aluminum, this switch measures, controls and switches pressures from vacuum to 500 psi. A snap action micro-switch eliminates the inconsistent operation of floating contacts found in similar designs. This UL recognized and CSA listed switch can be used for high and low limit control, safety shutdown and alarm functions for most industrial equipment applications. NSF approvals make these pressure switches an ideal choice for pressure control in demanding food and beverage applications. When the application is critical and space is limited, the Barksdale E1S and E1H Econ-O-Trol Pressure Switch are the ideal choice to meet your requirements.
