Application and Buying Notes

When replacing a stop light switch, the most important checks are the thread size, spanner size, and circuit style. This Tridon unit uses an M10 x 1.25 thread and a 14 mm spanner size, so it should only be considered where those measurements match the vehicle’s existing switch or the service information for the application.

The circuit is listed as normally closed, which is a critical detail because the switch operation must suit the vehicle’s brake light circuit. If the existing switch is a different circuit type, the replacement may not function correctly even if the thread appears to fit.

Part number TBS003 is the clearest identifier for ordering and cross-checking. If you are matching by visual comparison, remove the original switch and compare the thread, hex size, and terminal arrangement before fitting the new part.

The listing includes Daihatsu Applause and Daihatsu Charade references in the fitment data provided, but no model-year claim should be treated as confirmed unless it is checked against the vehicle records or the original part number. Use the catalog application details as a guide, not a substitute for physical confirmation.

Because stop light switches are part of the braking signal circuit, it is worth taking care with installation and adjustment. A correct thread match is only part of the job; the switch also needs to suit the vehicle’s circuit design and mounting position so the brake lamps operate as intended.

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 TBS003 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.

For part number TBS003, 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 DAIHATSU APPLAUSE, DAIHATSU APPLAUSE 1989, DAIHATSU APPLAUSE 1990, DAIHATSU APPLAUSE 1991. 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: Confirm compatibility by comparing part number TBS003, the M10 x 1.25 thread, the 14 mm spanner size, and the normally closed circuit against the existing switch and vehicle application before ordering.
