Description

Advance Truck Parts 5 PSI Heavy Duty Pressure Switch – 3-Terminal SPDT

SKU: W021280-5PSI | Brand: Advance Truck Parts USA

The Advance Truck Parts USA W021280-5PSI is an extended-duty universal pressure switch engineered for heavy-duty commercial trucks, off-road equipment, and industrial machinery. Designed with a versatile SPDT (Single Pole, Double Throw) 3-terminal configuration, this single unit replaces both dedicated Normally Open (N.O.) and Normally Closed (N.C.) switches.

Each terminal includes a dual-connection setup—featuring both a #8-32 screw and a 1/4" quick-connect male spade—allowing seamless installation with ring terminals or standard push-on connectors. Built with a zinc-plated steel hex base and high-temperature composite housing, it provides reliable switching for air, oil, fuel, and hydraulic circuits.

Key Features

Dual-Style Terminals: Equipped with both combination #8-32 screw terminals and 1/4" quick-connect blades for fast, tool-friendly wiring.
SPDT Universal 3-Terminal Design: Clearly marked C (Common), NO (Normally Open), and NC (Normally Closed) terminals to consolidate inventory across multiple single-circuit SKUs.
Direct Cross-Compatibility: Wire as Normally Open to replace 76583 / 76575, or Normally Closed to replace 76585 / 76577.
Heavy-Duty Durability: Rugged plated steel hex base resists high-vibration cracking, paired with a chemical-resistant diaphragm suitable for air brake, engine oil, and fuel systems.

Terminal Wiring Guide

C (Common): Connects to your incoming 12V / 24V power supply or ground line.
NO (Normally Open): Remains open at rest; activates/closes at 5 PSI. (Use for 76583 replacements)
NC (Normally Closed): Remains closed at rest; opens/shuts off at 5 PSI. (Use for 76585 replacements)
