Detroit Diesel 23511818 Pressure Switch - New (NOS)

Detroit Diesel pressure switch, OEM part number 23511818, in the original Detroit Diesel Corporation box (group 7.4598). Molded black housing with a brass 1/8" NPT male pressure port and three stud terminals for ring-terminal wiring — a Nason-style switch supplied as an OEM item for Detroit Diesel engine instrumentation and alarm/shutdown circuits. Application: Detroit Diesel engine electrical/instrument circuit as indicated on the OEM box; specific engine series, switch setpoint, and circuit function are not verified from the photos — the switch's own label is not legible. Buyer should confirm function and setpoint against the DDC parts book. Condition: New old stock (NOS) in an open, aged original box. The switch appears unused with clean threads and no installation marks. Not bench-tested — sold as NOS, untested. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
