Tridon Stop Light Switch TBS111

The Tridon Stop Light Switch, part number TBS111, is a dual circuit switch supplied as each. It is listed under auto elec accessories and fuses, breakers, relays and switches, which makes it a straightforward replacement item when you are dealing with brake light circuit faults and need the correct switch reference on hand.

The key electrical detail here is the dual circuit arrangement: Normally Open and Normally Closed. That is important when matching the switch to the vehicle’s brake light and related control logic, because the circuit configuration must suit the application. The listing also notes no spanner size and no thread detail are specified, so confirming the exact part number and application is the safest way to order.

Tridon identifies this item as a stop light switch with a two year warranty. For workshop or driveway replacement, the most useful identifiers are the Tridon brand, TBS111 part number, and the dual circuit specification. Those details are the best starting point when comparing the old switch, the vehicle application, and any catalogue reference you may already have.

Application and Buying Notes

When buying a stop light switch, the most important checks are the part number, the circuit type, and the vehicle application. This Tridon item is TBS111 and it is a dual circuit switch with Normally Open and Normally Closed operation, so the electrical configuration needs to match what the vehicle expects. If your removed switch carries a different identifier, do not assume it will interchange just because the general part name is the same.

The listing does not provide a spanner size or thread detail, so those fitting dimensions should be checked against the old switch or the vehicle specification before installation. That matters on brake light switches because even a correct electrical part can still be unsuitable if the physical fitment details do not align. Keep the original switch or its markings handy when cross-checking.

The fitment references supplied with this item point to a range of Citroen and Peugeot applications, including C3, C4, C5, C6, Dispatch, 207, 308, 406, 407, 508 SW, 607 and Expert variants. Those names are useful as a guide, but they should be treated as application references only. Confirm the exact vehicle model, year, and any other relevant details against the part number TBS111 before ordering.

For parts in the brake light circuit, it is worth being methodical rather than relying on appearance alone. The same vehicle family can use more than one switch arrangement, and this Tridon part is defined by its dual Normally Open / Normally Closed circuit design. Matching the part number and the circuit description gives you a much better chance of selecting the correct replacement the first time.

The two year warranty provides a useful level of purchase confidence, but it does not replace fitment checking. A correct-order decision still depends on matching the switch to the vehicle’s application and electrical requirements. If you are unsure, compare the removed part, catalogue reference, and the TBS111 identifier before fitting.

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 TBS111 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 TBS111 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS111, 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 CITROEN C3, CITROEN C3 2002, CITROEN C3 2003, CITROEN C3 2004, PEUGEOT 207, PEUGEOT 207 2006. 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 the Tridon part number TBS111 and the vehicle application details before ordering. The reported applications include several Citroen and Peugeot models, but the final check should always be made against the vehicle’s exact switch requirement.
