Tridon Stop Light Switch TBS042 M10 X 1.5 Dual Circuit

The Tridon Stop Light Switch, part number TBS042, is an electrical switch supplied as each and carries a two year warranty. It is listed as a stop light switch with a dual circuit arrangement, giving both Normally Open and Normally Closed operation in the one unit.

Key physical details for checking the job before purchase are the 14 mm spanner size and M10 x 1.5 thread. Those measurements matter because stop light switches need to match the threaded mounting point and be tightened with the correct tool size without forcing the body or thread.

This switch sits in the auto electrical accessories group and the fuses, breakers, relays and switches category. If you are replacing an existing stop light switch, the part number TBS042 and the thread specification are the clearest identifiers to compare before ordering.

Because brake light switch setups can vary between vehicles and even between model years, it is worth confirming the circuit type as well as the thread size. The dual Normally Open and Normally Closed arrangement indicates a more specific electrical function than a simple on/off switch, so the application must suit that configuration.

Application and Buying Notes

The most important checks on this Tridon stop light switch are the part number TBS042, the M10 x 1.5 thread and the 14 mm spanner size. If the mounting thread or tool size does not match the vehicle’s existing switch, the part is unlikely to be a direct replacement.

If you are replacing a brake or stop lamp switch, compare the removed part carefully before fitting. A stop light switch may look similar across different vehicles, but thread size, operating style and connector arrangement can differ. Matching the original part number where possible remains the safest way to avoid the wrong purchase.

The listed Subaru fitment data shows a number of applications, but the product details do not provide a full vehicle-by-vehicle confirmation in this listing. For that reason, it is sensible to verify the model, year and original switch details against the vehicle you are working on, especially if the vehicle is a Forester, Impreza, Legacy, Liberty, Outback, SVX or Tribeca.

The two year warranty applies to the supplied item itself, but warranty coverage does not replace fitment checking. Confirm the mounting thread, the circuit type and the original part reference before installation so the switch is appropriate for the job and the vehicle’s brake light 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 TBS042 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 TBS042 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS042, 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 SUBARU FORESTER, SUBARU FORESTER 1997, SUBARU FORESTER 1998, SUBARU FORESTER 1999. 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 the part number TBS042, the M10 x 1.5 thread, the 14 mm spanner size and the dual Normally Open/Normally Closed circuit arrangement before purchase or installation.
