Tridon Stop Light Switch TBS012 M10 X 1.25 Normally Closed

The Tridon Stop Light Switch, part number TBS012, is a single switch unit sold each for automotive electrical applications. It is identified with a 14mm spanner size, M10 x 1.25 thread, and a normally closed circuit, so those details should be checked carefully against the existing switch before ordering.

This switch sits in the motor vehicle controls category and carries a two-year warranty. For a stop light switch, the critical checks are the thread size, spanner size, and circuit type, because those are the practical points that determine whether the part matches the original setup in the vehicle.

Tridon lists this item under auto electrical accessories and fuse, breaker, relay and switch groups. If you are replacing a faulty stop light switch, matching the part number TBS012 and confirming the M10 x 1.25 thread and normally closed circuit will help avoid unnecessary returns or installation delays.

Application and Buying Notes

Before buying, compare the old switch to TBS012 and confirm the thread is M10 x 1.25, the spanner size is 14mm, and the circuit is normally closed. Those three details are the most useful compatibility checkpoints supplied here, and they matter more than a general description of the part.

If you are fitting the switch to a vehicle with an existing stop light switch, the safest approach is to match by part number and physical specification rather than relying on appearance alone. The wrong thread or circuit type can stop the brake light circuit from working as intended, even if the switch looks similar.

This part is sold as each, so it suits a direct replacement job where only one switch is needed. The two-year warranty adds a useful level of purchase confidence, but it does not replace the need to verify the application on the vehicle before installation.

Stop light switches can vary between models and production runs, including differences in thread and circuit operation. If your original switch has the same 14mm spanner size, M10 x 1.25 thread, and normally closed circuit, TBS012 is the specification set to compare against when confirming suitability.

Keep the original switch handy when ordering if possible, and check the threaded section carefully. The M10 x 1.25 thread and normally closed circuit are the clearest identifiers in the listing, and they are the best reference points for making an informed 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 TBS012 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 TBS012 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS012, 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.

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 matching part number TBS012 and checking the M10 x 1.25 thread, 14mm spanner size, and normally closed circuit against your original switch or vehicle application details before ordering.
