Discharge Pressure Switch

Wiring: Remove the two screws retaining the cover and cover gasket. A 1/2” NPT conduit connection is provided on the left hand side of the enclosure. Two cast-in knockouts for the 1/2” conduit are located on the side and back of the enclosure. These can easily be knocked out by placing the blade of a screwdriver in the groove and tapping sharply with a hammer. The three switch terminals are clearly labeled “common”, “normally open” and “normally closed”. For switches supplied with leadwires, the following color coding applies: Common-Yellow, Normally Closed-Orange, Normally Open-Brown.
