Ford Headlamp Switch Continuity Diagram - Off, Autolamp, Park, Fog Positions
Headlight switch internal contact diagrams showing electrical connections in Off, Autolamp, Parking, Headlamp, and Headlamp w/Foglamp positions.
This document is a switch continuity diagram, most likely for a headlamp/light switch, showing the internal electrical connections of a multi-terminal switch connector in five different switch positions. The connector face is drawn five times with terminals numbered 2, 5, and 6 in the top row and 7 through 12 in the bottom row. In the "Off" position, no terminals are connected. In the "Autolamp" position, terminals 7 and 8 are bridged. In the "Parking Lamp" position, terminals 10, 11, and 12 are connected together. In the "Headlamp" position, terminals 8 and 9 are connected, and terminals 10, 11, and 12 are connected together. In the "Headlamp w/Foglamp" position, all headlamp-position connections are present (8–9 and 10–11–12), plus an additional bridge between terminals 2 and 5 for the foglamps. A reader can use this chart to bench-test a light switch with an ohmmeter/continuity tester by verifying which pins should show continuity in each detent, helping diagnose a faulty switch versus a wiring problem. The document contains no year, make, model, part numbers, wire colors, or amperage data—only terminal numbers, connection paths, and position names.
