Tridon Stop Light Switch TBS037, M12 X 1.5, Normally Closed

The Tridon Stop Light Switch, part number TBS037, is a vehicle electrical switch supplied as a single unit each. It is identified with a 22mm spanner size, an M12 x 1.5 thread, and a normally closed circuit, so the fitting details need to match the brake light switch position and thread arrangement on the vehicle before purchase.

This switch sits in the AUTO ELEC ACCESSORIES group and is also listed under FUSES BREAKERS RELAYS SWITCHES. For workshop or retail ordering, the key identifiers are Tridon, TBS037, M12 x 1.5, and normally closed. Those details are the fastest way to check whether the part is the correct style for the application being serviced.

A two year warranty is listed for this switch. That gives a useful commercial reference, but it does not replace the need to confirm the thread size, spanner size, and circuit type against the vehicle application. Brake light switches are small parts, but the wrong thread or circuit arrangement can stop the switch from operating as intended.

Application and Buying Notes

Before ordering, confirm the switch on the vehicle uses an M12 x 1.5 thread and accepts a 22mm spanner size. Those two measurements are practical checks when comparing the existing switch, especially if the part is being replaced during a brake system or electrical fault diagnosis.

The circuit type is normally closed, which is a critical detail for a stop light switch. If the vehicle requires a different circuit arrangement, the lights may not respond correctly. Matching the circuit type is just as important as matching the thread size and part number TBS037.

The fitment list includes a range of Holden, HSV, and Toyota Lexcen applications, but the safest check is to compare the vehicle application and the actual part details together. Year, model family, and switch specification all matter, particularly on vehicles with multiple electrical variations across the range.

If you are replacing a worn or faulty switch, inspect the mounting thread and surrounding hardware before installation. A brake light switch should thread in cleanly and seat correctly; forcing an incorrect thread can damage the component or the vehicle housing. Using the correct part number and specification reduces that risk.

For trade customers, the most useful identifiers to match are Tridon, TBS037, M12 x 1.5, 22mm, and normally closed. Those details allow quick comparison against existing stock or the removed part without relying on assumptions about vehicle model alone.

The listed two year warranty is useful for purchase confidence, but the correct application still needs to be confirmed before the part is fitted. A switch can look similar to another one while differing in thread pitch or circuit operation, so the label and physical measurements should be checked together.

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 TBS037 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 TBS037 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS037, 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 HOLDEN ADVENTRA, HOLDEN ADVENTRA 2003, HOLDEN ADVENTRA 2004, HOLDEN BARINA, HSV AVALANCHE, HSV AVALANCHE 2003. 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 TBS037, the M12 x 1.5 thread, the 22mm spanner size, and the vehicle application details before ordering or fitting.
