Tridon Stop Light Switch TBS072 M12 X 1.25 Normally Closed

The Tridon Stop Light Switch, part number TBS072, is an electrical switch supplied as each and carries a two-year warranty. It is described as a normally closed circuit switch with a 17mm spanner size and an M12 x 1.25 thread, so the physical thread and operating style are both important checks before purchase.

As a brake or stop light switch, the key details are the thread size, the spanner size for installation, and the normally closed circuit arrangement. Those specifications matter because the switch must match the vehicle’s threaded mounting point and the intended circuit type, not just the general shape of the part.

This Tridon switch sits in the auto electrical accessories and fuses, breakers, relays, switches product groups. For buyers replacing an existing stop light switch, the most useful identifiers here are the Tridon brand, TBS072 part number, M12 x 1.25 thread, and normally closed circuit specification.

Application and Buying Notes

The most reliable buying check for this Tridon stop light switch is the part number TBS072, then the physical details: M12 x 1.25 thread, 17mm spanner size, and normally closed circuit. If the thread or circuit type differs from the existing switch, the part may not suit the vehicle even if the application name looks close.

The available fitment information includes Holden E Series, H Series, Monaro, Statesman, Sunbird, Torana, and WB references, with previewed E Series years from 1963 to 1965 and H Series years from 1965 to 1971. That is useful guidance, but the safest approach is still to compare the removed switch with the listed measurements and circuit arrangement.

When replacing a stop light switch, it is worth checking the mounting thread and the way the circuit operates before installation. A normally closed switch is defined by its operating state, so the electrical behaviour needs to match the vehicle’s intended brake light control setup, not only the external thread size.

If you are matching an existing genuine or aftermarket switch, keep the old unit on hand and compare the stamped or referenced part number, the thread diameter and pitch, and the wrench size needed to remove it. Those checks help avoid ordering a switch that looks similar but is not the correct electrical match.

This item is sold as one switch per order, which is useful if you are replacing a single faulty unit. The two-year warranty provides additional purchasing confidence, but it does not replace the need to confirm application details against the vehicle and the original part.

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 TBS072 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 TBS072 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS072, 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 E SERIES, HOLDEN E SERIES 1963, HOLDEN E SERIES 1964, HOLDEN E SERIES 1965. 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 using part number TBS072, M12 x 1.25 thread, 17mm spanner size, and normally closed circuit requirements before ordering.
