Application and Buying Notes

Before ordering, confirm the panel cut-out matches the listed 21 x 37 mm mounting hole size. That dimension is the main physical check for a rocker switch installation, and it should be matched to the existing opening or the space you plan to cut.

Also check the electrical requirements of the circuit. This switch is rated at 20 amp and is suitable for 12 or 24 volt systems, so it needs to be used within those limits. The 3-terminal, 1-pole SPST layout means it suits a simple on/off circuit rather than a multi-function switching setup.

The amber illumination is part of the switch design, so it is worth confirming that the lamp colour and illuminated style are what you want for the dash or control panel. If you are replacing an existing switch, the part number TDR11076 is the safest reference to compare against the old unit.

Because this is an electrical control component, proper terminal matching and circuit loading are just as important as the physical size. If the original switch has a different terminal count, different action, or a different cut-out size, it may not be interchangeable even if it looks similar from the front.

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 TDR11076 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 Amber Illuminated. Part number TDR11076 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 TDR11076, 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.

Compatibility note: Confirm compatibility by matching part number TDR11076, the 21 x 37 mm mounting hole, the 3-terminal SPST layout, and the 12 or 24 volt 20 amp rating before purchase.
