Tridon Stop Light Switch M12 X 1.5 Normally Closed TBS038

The Tridon Stop Light Switch is listed under part number TBS038 and is supplied as a switch, sold each. It is identified with an M12 x 1.5 thread and a normally closed circuit, which are the key details to check when matching it to the vehicle application.

This switch sits in the auto electrical accessories range and is grouped with fuses, breakers, relays and switches. The listed warranty is two years, which gives a clear reference point for buyers who want a replacement stop light switch with defined product identification and basic coverage.

Fitment data supplied for this part includes Audi and Volkswagen applications, including Audi 100 and Volkswagen Passat. Because stop light switches rely on thread size, circuit type and application matching, the part number TBS038 and the M12 x 1.5 thread should be confirmed before purchase.

For workshop or repair use, the important points are straightforward: this is a Tridon stop light switch, it uses a normally closed circuit, and it is sold as one unit. Those details matter when replacing a switch in a braking or lighting circuit, where the wrong thread or circuit arrangement will stop the part from matching correctly.

Application and Buying Notes

A stop light switch should be matched carefully because thread size and circuit type are essential to fit and function. For this Tridon part, the usable identifiers are TBS038, M12 x 1.5 and normally closed, so those details should be checked against the original switch or vehicle application before you buy.

The application listing points to Audi and Volkswagen coverage, including Audi 100 and Volkswagen Passat. That is useful guidance, but it is still best practice to confirm the exact vehicle match using the part number and the existing switch details, especially where the vehicle has had previous electrical repairs or component changes.

The two-year warranty applies to the supplied part, but it does not replace fitment checking. If the original switch uses a different thread size or circuit arrangement, this part will not be the right replacement even if the vehicle make appears in the application list.

Sold each, this part is intended as a single replacement switch rather than a kit. If you are working on brake light faults, it is sensible to verify the old switch markings, thread specification and connector arrangement before fitting a new unit, because the critical match points here are the thread and the normally closed circuit.

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 TBS038 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.

For part number TBS038, 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 AUDI 100, AUDI 100 1984, AUDI 100 1985, AUDI 100 1986, VOLKSWAGEN PASSAT, VOLKSWAGEN PASSAT 1996. 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: Confirm compatibility using part number TBS038, the M12 x 1.5 thread and the normally closed circuit, and compare these details with the vehicle application before ordering.
