Carling-Style Rocker Switch Wiring Diagram - Generator & House Battery Pinouts
Switch terminal wiring diagram sheet showing rocker-switch positions and positive, negative and output connections
This document is an instruction/wiring sheet for Carling-style rocker (Contura-type) switches, photographed with two physical switch bodies and two laser-etched rocker actuator covers labeled "GENERATOR" (lightning bolt icon) and "HOUSE BATTERY" (battery icon). The sheet shows terminal pinout diagrams for a double-pole ON/(ON) switch: terminals 1–3 for pole 1 (Positive 1 OUT switch down, IN, OUT switch up) and terminals 4–6 for pole 2 (Positive 2 OUT switch down, IN, OUT switch up). A second diagram covers an illuminated momentary/latching variant: terminal 8 indicator lamp (+), terminal 7 negative, terminal 2 positive in, terminal 3 positive out (latching), terminal 5 positive in (via a T2-T5 jumper), and terminal 6 positive out (momentary). Numbered notes explain that the switch ships with a pre-installed removable jumper between terminals 2 and 5, that the latching center ON position is between terminals 2 and (cut off), the momentary top ON is between terminals 5 and (cut off), and that the latching ON is maintained while the momentary position is pressed. Common uses listed are START/RUN/OFF for engine switches and WASH/WIPER/OFF for wiper/washer fluid switches. The document is generic to the switches, not specific to any vehicle.

Frequently asked questions
- What do the terminals on this rocker switch do?
- Per the diagram: terminal 1 is Positive 1 (OUT) with the switch down, terminal 2 is Positive 1 (IN), terminal 3 is Positive 1 (OUT) with the switch up; terminals 4, 5, and 6 are the same functions for Positive 2 (the second pole).
- How is the illuminated momentary/latching version wired?
- Terminal 8 is the indicator lamp (+), terminal 7 is negative, terminal 2 is Positive (IN), terminal 3 is Positive (OUT) latching, terminal 5 is Positive (IN) connected via a T2-T5 jumper, and terminal 6 is Positive (OUT) momentary.
- What is the pre-installed jumper on the switch for?
- The sheet states the switch comes with a pre-installed but removable jumper between terminals 2 and 5, normally left in place unless separating the momentary and latching positions.
- What are common uses listed for this switch?
- START/RUN/OFF for engine switches and WASH/WIPER/OFF for wiper/washer fluid switches.
- What labels are on the included rocker covers?
- One cover is labeled GENERATOR with a lightning bolt symbol; the other is labeled HOUSE BATTERY with a battery symbol.
