Tridon Stop Light Switch TBS133 4 Pin Resistance Circuit

The Tridon Stop Light Switch, part number TBS133, is a 4 pin switch with a resistance circuit. It is supplied as each and sits in Tridon’s auto electrical accessories range, under fuses, breakers, relays and switches.

A stop light switch is a small but important control component in the brake light circuit, so matching the part number and terminal style matters. This unit is identified as TBS133 and is listed with no spanner size and no thread detail, which makes the part reference and application check the safest way to confirm it before ordering.

Tridon backs this switch with a two year warranty, and the listed specifications keep the focus on the electrical setup rather than vehicle assumptions. The confirmed details here are the 4 pin layout, resistance circuit, each unit sale, and the TBS133 part number.

Fitment references supplied for this item include a range of Audi, Skoda, Subaru, Toyota and Volkswagen applications. Because the listing does not provide a full vehicle-specific breakout here, the part number and application details should be checked carefully against the vehicle already in the workshop or on the registration record.

Application and Buying Notes

For a stop light switch, the main checkpoints are the part number, pin count and circuit type. This Tridon unit is TBS133, uses 4 pins, and is described as a resistance circuit switch, so those details need to match the vehicle’s original setup before purchase.

The listing does not specify a spanner size or thread, so do not rely on those details for identification. If the existing switch on the vehicle is damaged or unreadable, compare the connector layout, wiring arrangement and any stamped part references before fitting.

The fitment references include a broad range of Audi, Skoda, Subaru, Toyota and Volkswagen applications, but the safest confirmation is still the vehicle application against TBS133. That is especially important on brake light switches, where the wrong electrical style or terminal count can prevent correct operation.

This part is supplied individually, which suits a single failed switch replacement rather than a kit. The two year warranty provides a clear commercial reference, but it does not replace the need to confirm compatibility with the vehicle already in front of you.

Keep in mind that the fitment data shown here is a compatibility guide, not a substitute for a final vehicle check. The part number TBS133 remains the strongest identifier, and it should be used alongside the application details when confirming the correct switch.

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 TBS133 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 TBS133 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS133, 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 A1, AUDI A1 2013, AUDI A1 2014, AUDI A1 2015, SKODA FABIA, SKODA FABIA 2013. 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.

Compatibility note: Please confirm fitment by checking part number TBS133, the 4 pin connector layout and the vehicle application details before ordering or installing.
