{"product_id":"a9304940-tridon-stop-light-switch","title":"Tridon Stop Light Switch TBS023 M12 X 1 Normally Closed","description":"\u003cp\u003eThe Tridon Stop Light Switch, part number TBS023, is a switch type unit sold each. It uses an M12 x 1 thread, a 17 mm spanner size, and a normally closed circuit, so it is important to compare the thread and circuit arrangement against the original switch before ordering.\u003c\/p\u003e\n\u003cp\u003eThis switch sits in the auto electrical accessories range and is listed under fuses, breakers, relays and switches. For buyers working on older BMW and Volvo applications, the key check points are the part number TBS023, the M12 x 1 thread, and the normally closed circuit specification.\u003c\/p\u003e\n\u003cp\u003eThe unit carries a two year warranty and is branded Tridon. Those details are useful when you are cross-checking a replacement stop light switch for the correct physical fit and electrical function, especially where the original switch has worn threads, unreliable pedal input, or intermittent brake light operation.\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: TBS023\u003c\/li\u003e\n\u003cli\u003eM12 x 1 thread\u003c\/li\u003e\n\u003cli\u003e17 mm spanner size\u003c\/li\u003e\n\u003cli\u003eNormally closed circuit\u003c\/li\u003e\n\u003cli\u003eSold each\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.: TBS023\u003c\/li\u003e\n\u003cli\u003eUnit of measure: Each\u003c\/li\u003e\n\u003cli\u003eThread: M12 x 1\u003c\/li\u003e\n\u003cli\u003eSpanner size: 17 mm\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eListed fitment applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 3\u003c\/li\u003e\n\u003cli\u003eBMW 3 1975\u003c\/li\u003e\n\u003cli\u003eBMW 3 1976\u003c\/li\u003e\n\u003cli\u003eBMW 3 1977\u003c\/li\u003e\n\u003cli\u003eBMW 3 1978\u003c\/li\u003e\n\u003cli\u003eBMW 3 1979\u003c\/li\u003e\n\u003cli\u003eBMW 3 1982\u003c\/li\u003e\n\u003cli\u003eBMW 3 1983\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, check the original switch against the Tridon TBS023 using the thread size, the 17 mm spanner size, and the circuit type. The listed M12 x 1 thread and normally closed circuit are the most important physical and electrical match points for this part.\u003c\/p\u003e\n\u003cp\u003eFitment listings include BMW 3 models from 1975 through 1987 and Volvo 240 applications from 1979 through 1990, with additional grouped applications shown for BMW 5, BMW 6, BMW 7, Volvo 260, Volvo 265, Volvo 740, Volvo 760, Volvo 850, Volvo 940 and Volvo 960. Use those applications as a guide, but still verify the switch fitted to the vehicle.\u003c\/p\u003e\n\u003cp\u003eStop light switches are simple in appearance but specific in operation. A normally closed circuit must match the vehicle’s brake light circuit design, and the thread must suit the mounting point. If either detail differs, the switch may not install correctly or may not operate as intended.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a failed brake light switch, compare the old unit’s part number where possible. The TBS023 reference is the clearest identifier here, along with the M12 x 1 thread and 17 mm spanner size. These details are more reliable than a broad vehicle model match on its own.\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 TBS023 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. TBS023, 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 TBS023 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 TBS023, 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 BMW 3, BMW 3 1975, BMW 3 1976, BMW 3 1977, VOLVO 240, VOLVO 240 1979. 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.\u003c\/p\u003e\n\u003cp\u003eThe listed warranty is Two Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm fitment by matching the part number TBS023, the M12 x 1 thread, the 17 mm spanner size, and the normally closed circuit against the existing switch and vehicle application before purchase.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the part number for this Tridon stop light switch?\u003c\/h4\u003e\n\u003cp\u003eThe part number is TBS023.
