Thunder Rocker Switch Mom On-off-mom On Spdt 12/24V Blue Illuminated 20A TDR11007

The Thunder rocker switch is a momentary-on / off / momentary-on SPDT switch with 3 positions, 6 terminals and blue illumination. It is set up for 12 or 24 volt systems, with contacts rated at 20A @ 12V and a mounting hole size of 20mm x 36mm. The part number is TDR11007.

This is a rocker style switch supplied as a single unit, with 5 blade terminals noted in the product features and a 1kg listed weight. For installations where the switch position, terminal count and panel opening matter, the key checks are the 20mm x 36mm mount size, the 12 or 24 volt supply, and the momentary SPDT action.

For buyers replacing an existing switch, the most useful identifiers here are the Thunder brand, TDR11007 part number, 1 pole configuration, and the blue illuminated face. If you are matching a dash, console or accessory panel switch, confirm both the electrical rating and the physical cut-out before ordering.

Application and Buying Notes

Before buying, confirm that your application calls for a momentary-on / off / momentary-on SPDT rocker switch and that the panel opening is 20mm x 36mm. The listed electrical rating is 20A @ 12V, so the intended load and circuit design should be checked against that figure rather than assumed.

The switch is specified for 12 or 24 volt use, which makes it suitable for many automotive and accessory setups, but voltage alone does not confirm compatibility. You should match the terminal arrangement, the number of poles, and whether your original switch used blue illumination and the same blade-terminal layout.

Where a replacement switch is being fitted, part number matching is often the safest check. TDR11007 is the listed part number for this Thunder switch, and it is the best reference point if you are comparing an old switch, a service listing, or a panel cut-out template.

If you are unsure about the wiring side, count the terminals on your existing switch and compare the switch action carefully before removal. This model is listed with 6 terminals and a single pole SPDT arrangement, so it should only be used where that configuration is required.

Physical fit is just as important as electrical fit. A switch with the wrong mount width or mount length can leave you with a loose fit or a panel that needs modification, so measure the opening before purchase rather than relying on appearance alone.

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 TDR11007 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 Rocker Switch Mom On/Off/Mom On SPDT 12 or 24V Blue Illuminated (Contacts Rated 20A @ 12V). Part number TDR11007 should be checked first. Listed voltage is 12 or 24. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TDR11007, 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 12 or 24 and output 20 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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by matching the part number TDR11007, the 20mm x 36mm mounting hole size, the 12 or 24 volt supply, and the Mom On - Off - Mom On SPDT switch action against your existing application before ordering.
