Thunder OE Style Push Button Switch Roof Light 12V 3A TDR11090

The Thunder OE Style Push Button Switch Roof Light is a 12V switch rated at 3A and supplied as one each. It is identified by part number TDR11090 and is listed as an OE style push switch for roof light applications in Holden and Isuzu vehicles.

Physical size matters when replacing a dash or accessory switch, and this unit measures 34mm x 22mm. The switch action is On - Off - SPST, with blue LED illumination for the switch face and a wiring setup that includes black for earth, red for 12V input, green for 12V output, and blue for the dash light circuit as an optional connection.

The listing notes suitability for Isuzu and Holden applications, with example fitment references to Isuzu D-Max 2013-2016 and Holden Colorado 2013-2016. As with any electrical switch, the correct match depends on the mounting opening, wiring needs, and the vehicle application, so part number TDR11090 and the 34mm x 22mm mount size are the key checks before ordering.

Application and Buying Notes

For a clean replacement, compare the switch opening in your dash or roof panel with the 34mm x 22mm mount size. The part is described as an OE style push button switch and uses an On - Off - SPST action, so it is best suited to simple switched accessory circuits rather than more complex multi-function switching.

The electrical rating is 12V and 3A, so it should be matched to the load you intend to control. The supplied wiring code is black for earth, red for 12V input, green for 12V output, and blue for the optional dash light circuit. Those connections should be checked against your vehicle’s loom or planned installation before fitting.

Because fitment is only listed for certain Isuzu and Holden applications, the part number TDR11090 should be used as the primary reference when comparing alternatives. If your vehicle is a D-Max or Colorado from the years noted, verify the panel shape, switch cavity, and wiring arrangement rather than relying on the vehicle badge alone.

The blue LED illumination is a useful feature where a lit switch is preferred, but the actual appearance and function depend on the correct wiring of the optional blue dash light circuit. If the circuit is not being used, the switch can still be assessed against the main earth, input, and output wires for your application.

One year warranty cover is listed for this item. Even so, electrical parts should be checked for correct sizing, correct voltage, and correct circuit type before installation, especially where the switch is being added to an existing accessory setup or replacing a factory unit.

As a practical buying step, measure the mounting aperture and compare it with the 34mm x 22mm dimensions, then confirm the intended circuit load stays within the 3A rating. Those two checks will resolve most compatibility questions before the switch is installed.

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 TDR11090 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.

Thunder OE Style Push Button Switch Roof Light, Suits Holden and Isuzu. Part number TDR11090 should be checked first. Listed voltage is 12V. Listed output rating is 3. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TDR11090, 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 voltage 12V and output 3 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Please confirm fitment by matching part number TDR11090, the 34mm x 22mm mount size, the 12V 3A rating, and the vehicle wiring/application details before ordering.
