{"product_id":"a9573154-tridon-stop-light-switch","title":"Tridon Stop Light Switch TBS146 Normally Closed","description":"\u003cp\u003eThe Tridon Stop Light Switch, part number TBS146, is a single switch sold each and identified as a normally closed circuit unit. It sits in the auto electrical accessories group and is listed under fuses, breakers, relays and switches, so it belongs in the vehicle’s brake light control circuit rather than as a general-purpose electrical item.\u003c\/p\u003e\n\u003cp\u003eThis switch is supplied under the Tridon brand and carries a two-year warranty. The listed features are limited but useful for identification: spanner is not specified, thread is not specified, and the circuit is normally closed. Those details matter when matching the part to the original switch arrangement on the vehicle.\u003c\/p\u003e\n\u003cp\u003eKnown fitment references include Holden Colorado, Holden Rodeo and Isuzu D-Max applications. Sample applications provided include Holden Colorado 2008 to 2012, Holden Rodeo 2003 to 2007, and Isuzu D-Max 2007 to 2017. That makes the part number and the application list the key checks before ordering.\u003c\/p\u003e\n\u003cp\u003eBecause stop light switches can differ by circuit type, thread form and mounting style, the safest approach is to match TBS146 against the vehicle’s original switch details before purchase. A normally closed circuit should only be used where that operating style is required by the vehicle’s brake light system.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTridon stop light switch\u003c\/li\u003e\n\u003cli\u003ePart number TBS146\u003c\/li\u003e\n\u003cli\u003eNormally closed circuit\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003cli\u003eTwo-year warranty\u003c\/li\u003e\n\u003cli\u003eListed for auto electrical accessory applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tridon\u003c\/li\u003e\n\u003cli\u003eProduct type: Switch\u003c\/li\u003e\n\u003cli\u003eDescription: Tridon Stop Light Switch\u003c\/li\u003e\n\u003cli\u003ePart No.: TBS146\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally Closed\u003c\/li\u003e\n\u003cli\u003eUnit of measure: Each\u003c\/li\u003e\n\u003cli\u003eWarranty: Two Years\u003c\/li\u003e\n\u003cli\u003eProduct group 1: Auto Elec Accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment references provided\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHolden Colorado: 2008, 2009, 2010, 2011, 2012\u003c\/li\u003e\n\u003cli\u003eHolden Rodeo: 2003, 2004, 2005, 2006, 2007\u003c\/li\u003e\n\u003cli\u003eIsuzu D-Max: 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the part number TBS146 with the switch currently fitted to the vehicle. The listed fitment references cover Holden Colorado, Holden Rodeo and Isuzu D-Max applications, but the important detail on this item is the normally closed circuit, along with the unspecified spanner and thread details.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a brake light switch, the operating style needs to suit the vehicle’s original circuit arrangement. A normally closed switch is not a generic substitute for every stop light application, so checking the old part’s markings, connector arrangement and mounting style is the right way to avoid a mismatch.\u003c\/p\u003e\n\u003cp\u003eThe fitment references include Holden Colorado 2008 to 2012, Holden Rodeo 2003 to 2007, and Isuzu D-Max 2007 to 2017. Even within those ranges, variations can occur, so the vehicle build details and the existing switch identification should be confirmed before purchase.\u003c\/p\u003e\n\u003cp\u003eThis part is sold each and sits in the vehicle’s electrical switching category. If the old switch has a different thread form, spanner size or circuit type, do not assume interchangeability. Those items are not specified here, so the part number and application check become the main buying safeguards.\u003c\/p\u003e\n\u003cp\u003eThe two-year warranty applies to the item as supplied, but warranty coverage does not replace fitment checking. Matching TBS146 to the original brake light switch is still necessary, especially where a vehicle has had previous repairs, altered wiring or a non-original switch fitted.\u003c\/p\u003e\n\u003cp\u003eFor workshop or DIY use, it is sensible to inspect the existing switch before removing it completely. Confirm the listed vehicle application, compare the part number, and make sure the normally closed circuit matches the original stop light operation. That is the most reliable way to reduce returns and delays.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number TBS146 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty Two Years, Product Group 1 AUTO ELEC ACCESSORIES, Part No. TBS146, Brand TRIDON, Description Tridon Stop Light Switch, Product Group 2 FUSES BREAKERS RELAYS SWITCHES.\u003c\/p\u003e\n\u003cp\u003eTridon Stop Light Switch. Part number TBS146 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number TBS146, 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.\u003c\/p\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include HOLDEN COLORADO, HOLDEN COLORADO 2008, HOLDEN COLORADO 2009, HOLDEN COLORADO 2010, ISUZU D-MAX, ISUZU D-MAX 2007.
