What do the terminals on this rocker switch do?

Terminals 1, 2, 3 are Positive 1 OUT (switch down), IN, and OUT (switch up); terminals 4, 5, 6 are the same for Positive 2. On the illuminated version, 8 is the indicator lamp (+), 7 is negative, 2 is positive in, 3 is positive out (latching), 5 is positive in, and 6 is positive out (momentary).

What is the jumper between terminals 2 and 5 for?

The switch comes with a pre-installed but removable T2-T5 jumper connecting terminals 2 and 5. It is normally left in place unless separate feeds are needed for the momentary and latching positions.

Which terminals are used for the latching and momentary positions?

The latching center ON position is between terminals 2 and 3, while the momentary top ON position is between terminals 5 and 6. The latching center ON position is maintained while the momentary position is pressed.

What labels are on the included switch covers?

One actuator cover is labeled GENERATOR with a lightning bolt icon, and the other is labeled HOUSE BATTERY with a battery icon.

This document is a photographed instruction/wiring sheet for Carling-style rocker switches, shown alongside two physical switch bodies and two snap-on actuator covers labeled "GENERATOR" (lightning bolt icon) and "HOUSE BATTERY" (battery icon). The sheet provides terminal pinout diagrams for a DPDT-style ON/(ON) rocker switch: terminals 1 (Positive 1 OUT, switch down), 2 (Positive 1 IN), 3 (Positive 1 OUT, switch up), 4 (Positive 2 OUT, switch down), 5 (Positive 2 IN), and 6 (Positive 2 OUT, switch up). A second diagram covers an illuminated latching/momentary variant: terminal 8 = indicator lamp (+), 7 = negative, 2 = positive in, 3 = positive out (latching), 5 = positive in (via a pre-installed T2-T5 jumper), and 6 = positive out (momentary). Numbered notes explain that a removable jumper joins terminals 2 and 5, that the latching center ON position uses terminals 2/3, that the momentary top ON position uses terminals 5/6, and that the latching center ON position is maintained while the momentary position is pressed. Common uses listed include START/RUN/OFF for engine switches and WASH/WIPER/OFF for wiper/washer fluid switches. Useful for anyone wiring generator or house-battery rocker switches in an RV or truck upfit.
