Tridon Stop Light Switch TBS051

The Tridon Stop Light Switch TBS051 is a dual circuit switch supplied as each unit, with the listed circuit arrangement noted as Normally Open and Normally Closed. It sits in the automotive controls category and is identified here as a Tridon switch with a two-year warranty.

For buyers matching an existing part, the key identifiers are Brand: Tridon, Part No.: TBS051, and Description: Tridon Stop Light Switch. Those details matter because stop light switches can vary by circuit layout, thread arrangement and physical fit, even where the application name looks similar.

The product notes list the spanner and thread fields as blank, so the safest way to approach purchase is by confirming the part number against the vehicle application and the switch specification. The supplied fitment data includes Audi A3, Audi TT, Volkswagen Bora, Volkswagen Golf, and Volkswagen Transporter / Caravelle references.

This is a straightforward electrical switch item rather than a universal accessory. If you are replacing a brake or stop light switch, the dual circuit setup is the most important functional detail to check alongside the exact TBS051 part number and the vehicle application listed for your vehicle.

Application and Buying Notes

When replacing a stop light switch, the best starting point is the part number TBS051. The supplied details also show a dual circuit with both Normally Open and Normally Closed operation, so the electrical configuration needs to match the vehicle’s original setup, not just the shape of the old part.

Fitment references are listed for Audi A3, Audi TT, Volkswagen Bora, Volkswagen Golf and Volkswagen Transporter / Caravelle, with sample year coverage shown for Audi A3 from 1997 through 2007, Volkswagen Bora from 1999 through 2005, and Volkswagen Golf from 1998 through 2000. If your vehicle falls outside those references, do not assume compatibility without checking the part number and application details carefully.

The spanner and thread fields are not provided here, which means you should compare the old switch directly before ordering if the vehicle has been modified, repaired previously, or already has a non-standard replacement fitted. In brake light switching circuits, the correct electrical operation is just as important as the physical mounting arrangement.

This switch is listed as one each and carries a two-year warranty. That makes it suitable as a direct replacement item where the original specification is known, but the final check should always be the same: confirm the TBS051 part number, confirm the dual circuit arrangement, and confirm the vehicle application against the existing part.

If you are fitting this to a Volkswagen or Audi model, check the original switch label or removed unit for any matching identifiers before purchase. Matching the part number and the circuit type is the most reliable way to avoid a mismatch on a stop light switch, particularly where several switch styles can appear similar at a glance.

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 TBS051 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.

Tridon Stop Light Switch. Part number TBS051 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS051, 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.

Compatibility note: Confirm fitment by matching part number TBS051, the dual normally open / normally closed circuit arrangement, and the vehicle application details before purchase. If your vehicle is not clearly covered by the listed applications, compare the removed switch directly rather than relying on appearance alone.
