Thunder Rocker Switch On/off Spst 12V Illuminated 20A TDR11061

The Thunder rocker switch is an illuminated On-Off SPST switch rated at 20A at 12V, with part number TDR11061. It is a 2-pole, 4-terminal switch designed for straightforward control applications where a compact 12V rocker is needed.

This switch uses a green illuminated lamp and has a mount size of 20mm x 35mm, with a stated mount length of 34.5mm. Those measurements matter when checking a dash, panel, or console opening before purchase, especially where space is tight or the existing cut-out must be matched closely.

If you are replacing a failed switch or fitting a new accessory control, the key checkpoints here are the 12V rating, 20A contact rating, SPST On-Off action, and the 4-terminal layout. The unit weighs .1kg and is sold each, with a one year warranty listed.

Application and Buying Notes

Before buying, confirm the panel opening and the switch body dimensions. The listed mount size is 20mm x 35mm, with a mount length of 34.5mm, so the physical cut-out and clearance behind the panel should be checked carefully against your application.

Electrical matching is just as important as the hole size. This switch is specified as 12V with a 20A contact rating, so it should be matched to a 12V circuit and used within the stated current rating. It is an SPST On-Off rocker with 4 terminals, so the wiring arrangement needs to suit that configuration.

The green illumination is useful where a visible switched position is preferred, but the lamp colour does not change the electrical requirements. If you are replacing an existing switch, the safest approach is to compare the part number TDR11061, the terminal count, the 2-position On-Off action, and the mounting dimensions before ordering.

For accessory installs, take care with load type and wiring quality. A switch rated at 20A at 12V still needs correct circuit protection, suitable connectors, and sound earth and feed arrangements. If the existing switch has a different terminal layout or a different cut-out size, it should not be assumed to be a direct replacement without checking all dimensions and wiring details.

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 TDR11061 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 On/Off SPST 12V Illuminated (Contacts Rated 20A @ 12V). Part number TDR11061 should be checked first. Listed voltage is 12. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TDR11061, 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 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.

Compatibility note: Confirm fitment by comparing part number TDR11061, the 12V 20A rating, the 4-terminal SPST On-Off layout, and the 20mm x 35mm mount size with your existing switch and panel opening before ordering.
