Tridon Stop Light Switch TBS004 M10 X 1.25 Normally Closed

The Tridon Stop Light Switch, part number TBS004, is a switch supplied as a single unit for automotive electrical use. It is listed with a 14mm spanner size, an M10 x 1.25 thread and a normally closed circuit, so it is important to match those details to the application before ordering.

This switch sits in the Tridon range under auto electrical accessories and is grouped with fuses, breakers, relays and switches. For a replacement part like this, the thread size, circuit type and part number are the key checks that matter most when comparing against the original item.

If you are replacing a stop light switch, confirming the M10 x 1.25 thread and the normally closed circuit is just as important as the vehicle listing. The wrong circuit type or thread can stop the switch from installing correctly or operating as intended.

Application and Buying Notes

When matching a stop light switch, the most useful identifiers here are TBS004, M10 x 1.25 thread and normally closed circuit. Those details need to align with the vehicle or the replacement part already fitted, because stop light switches can vary in thread pitch, physical size and electrical operation even when they look similar.

The 14mm spanner size gives you a practical installation check. If the existing switch is removed for comparison, you can verify the thread and the wrench size before fitting the replacement. That is often the quickest way to avoid a mismatch on older vehicles or when previous repairs have altered the original part.

This switch is supplied as an each item and carries a two year warranty. That makes it straightforward to order as a direct replacement where the part number and application match, but it is still wise to check the connector arrangement, thread engagement and circuit operation against the original component before final installation.

Fitment references include Daihatsu Charade applications across model years 1983 through 1987. Even with that listing, buyers should still confirm the exact replacement by part number and physical details, because model ranges can overlap and small production changes can affect switch type.

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 TBS004 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 TBS004 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS004, 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 CHARADE, DAIHATSU CHARADE 1983, DAIHATSU CHARADE 1984, DAIHATSU CHARADE 1985. 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 part number TBS004, the M10 x 1.25 thread, the 14mm spanner size and the normally closed circuit before purchase or installation.
