OEX Stop Light Switch OSL20

The OEX Stop Light Switch, part number OSL20, is a switch sold as each and identified in the electrical parts group. It is listed under engine management and carries a two year warranty. For buyers replacing a brake light switch, the part number is the key identifier to check before ordering.

This switch is described as an OEX product and the stated description is OEX Stop Light Switch. The available product details also note manufactured to OEM specifications, which is the main specification supplied for this item. That makes the part number OSL20 and the application details the most important checks when matching a replacement.

Fitment information is provided for a range of Ford and Holden vehicles, including Ford Cortina, Ford Fairlane, Ford Fairmont, Ford Falcon, Ford LTD, Holden H Series, Holden Monaro, Holden Statesman, Holden Sunbird, Holden Torana and Holden WB. Because these applications are grouped by make and model family, it is worth confirming the exact vehicle and year against the listing before purchase.

Application and Buying Notes

When matching a stop light switch, the safest starting point is the part number OSL20 and the vehicle application details. The fitment coverage supplied includes several Ford and Holden model families, but exact interchange can depend on year, body style and system variation, so the vehicle should be checked carefully before ordering.

The specification listed for this part is manufactured to OEM specifications. That makes correct identification important, because the switch needs to suit the brake light circuit and associated mounting or actuator arrangement used on the vehicle. If the original part has a different number, connector style or mounting design, compare those details before fitting.

This item is sold as each, so it is intended as an individual replacement switch rather than a kit. The two year warranty is also listed, which gives a clear reference point for the product offering, but it does not replace the need to confirm fitment against the vehicle and the original switch details.

For older Ford and Holden applications in the fitment coverage, year-specific differences can matter. Examples shown in the application data include Ford Cortina 1977 to 1982 and Holden H Series 1971 to 1980, so checking the exact model year is a sensible step. If the vehicle falls within one of the named families, use the part number OSL20 as the final check before purchase.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number OSL20 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Stop Light Switch. Part number OSL20 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number OSL20, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD CORTINA, FORD CORTINA 1977, FORD CORTINA 1978, FORD CORTINA 1979, HOLDEN H SERIES, HOLDEN H SERIES 1971. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is Two Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility using part number OSL20 and the exact vehicle application details before ordering. Fitment is listed for selected Ford and Holden model families, but the correct match still depends on the vehicle year, configuration and original switch details.
