Tridon Stop Light Switch TBS140

The Tridon Stop Light Switch, part number TBS140, is a dual circuit switch supplied as one each. It is listed under auto elec accessories and grouped with fuses, breakers, relays and switches, which makes it a sensible choice when you are replacing a brake light switch in the vehicle’s electrical control circuit.

Key details to note are the dual circuit arrangement and the normally open / normally closed operation. Those switching characteristics matter because the stop light circuit needs the correct electrical behaviour for the brake lights to function as intended. The listing does not provide spanner or thread details, so those points should be checked against the original switch before fitting.

This Tridon switch is covered by a two year warranty and is identified as TBS140. For buyers comparing options, the part number and circuit type are the most useful identifiers here. If you are matching an existing switch, confirm the physical style, connector arrangement and vehicle application before ordering.

Application and Buying Notes

When replacing a stop light switch, the part number TBS140 is the first check to make, followed by the circuit arrangement. This switch is listed as dual with normally open and normally closed functions, so it should only be compared with the original switch if those electrical details match. The listing does not provide thread or spanner dimensions, so physical interchange should not be assumed from the product name alone.

The fitment information points to Hyundai and Kia passenger vehicles, including Accent, Elantra, i30, i40, i45, Veloster, Cerato, Cerato Koup, Optima, Rio and Rondo. Sample applications extend across Hyundai Accent 2010 to 2019 and Kia Cerato 2013 to 2016. That is useful guidance, but it is still important to confirm the exact vehicle, year and brake switch style against the existing part before ordering.

For anyone diagnosing brake light faults, a stop light switch needs to match the vehicle’s original electrical layout. The dual circuit design listed here may be suitable where the factory switch uses both normally open and normally closed contacts, but compatibility should be checked carefully. A mismatch can affect brake light operation, and the listing does not claim any broader vehicle coverage beyond the applications noted.

This part is sold individually as one each, which is worth checking if you are replacing more than one component in the same system. The two year warranty offers a useful level of backing, but it does not replace fitment verification. Matching the original part number, connector style and application details remains the safest way to confirm you are ordering 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 TBS140 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 TBS140 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS140, 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 HYUNDAI ACCENT, HYUNDAI ACCENT 2010, HYUNDAI ACCENT 2011, HYUNDAI ACCENT 2012, KIA CERATO, KIA CERATO 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.

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: Please confirm fitment using part number TBS140 and the exact vehicle application details before ordering. Check the original switch’s circuit type, connector style and physical dimensions, as spanner and thread details are not provided here.
