Installation instructions for OMEGA PSW27, PSW28 & PSW29 Series: Pressure and
vacuum switches, compact, rugged, pre-fixed setpoint.
General
These reliable, compact single pole switches are used in pressure and vacuum applications where
moderate accuracy is sufficient. The fixed setpoint is factory set.
Additional Information
Temperature Range: -10 to 75°C (14 to 167°F)
Setpoint Accuracy: +/- 10% at 70°F. Note: pressure settings may change over the temperature range.
Pressure Connection:
PSW27: 1/8" NPT male.
PSW28: Center spout for 1/8" ID tubing. Provided with 9/16-18
mounting nut.
PSW29: Radial spout for 1/8" ID tubing.
Approvals: UL recognized, CSA certified, microswitches bear the ENEC & CE Mark.
