Thunder Rocker Switch On/off Spst 12 Or 24V Blue Illuminated 20A TDR11022

The Thunder rocker switch, part number TDR11022, is an On/Off SPST switch designed for 12 or 24 volt applications and fitted with blue illumination. It is listed with contacts rated at 20A at 12V, making the electrical rating and operating voltage clear before you start matching it to your setup.

This switch has 5 terminals, 1 pole, and 2 positions, with a rocker-style action and illuminated blue lamp. The mounting size is 36 x 20 mm, so it is important to check your panel opening carefully before ordering, especially where space is tight in a dash, console, or accessory panel.

It is described as a front diff switch, which gives a useful application reference for buyers looking for a simple illuminated On/Off control. The unit is sold each, carries a one year warranty, and sits within auto electrical accessories and fuses, breakers, relays, and switches product groups.

Application and Buying Notes

When checking suitability, start with the part number TDR11022, the 12 or 24 volt rating, and the 20A current rating at 12V. Those three details are the most practical starting points for confirming whether the switch matches the electrical demands of the circuit you want to control.

The mounting size is 36 x 20 mm, so panel fit is just as important as electrical suitability. Measure the opening in the vehicle or accessory panel before purchase, and allow for the rocker body and terminal clearance behind the face of the panel.

Because the switch is listed as a front diff switch, it may suit that type of use where a simple illuminated On/Off control is required. Even so, the buyer still needs to confirm the circuit load, terminal layout, and panel space against the existing setup rather than assuming the switch can be used everywhere a rocker switch is needed.

The switch has 5 terminals and a single pole, so it is worth checking the original wiring arrangement before installation. If you are replacing a switch, compare the physical connector style, the number of wires or terminals used, and the switching function so the replacement matches the existing circuit correctly.

Blue illumination can be useful where switch identification matters at night or in low light, but the lamp colour should be treated as a visual feature rather than an electrical substitute. The main compatibility checks remain voltage, current rating, terminal count, and the 36 x 20 mm mount size.

A one year warranty is listed, which is helpful for purchase confidence, but it does not replace the need to verify fitment before fitting. In vehicle electrical work, the safest approach is to confirm the part number, the application, and the mounting dimensions before the panel is modified or the old switch is removed.

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 TDR11022 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.

Additional published details for cross-checking include Part No. TDR11022, Brand THUNDER, Description Thunder Rocker Switch On/Off SPST 12 or 24V Blue Illuminated (Contacts Rated 20A @ 12V), Mount Width 20mm, Power Rating (Amp) 20, Voltage 12 or 24, Mount Length 36mm, Number of Positions 2, Switch Illumination Illuminated.

Thunder Rocker Switch On/Off SPST 12 or 24V Blue Illuminated (Contacts Rated 20A @ 12V). Part number TDR11022 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 TDR11022, 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 part number TDR11022, the 12 or 24 volt rating, the 20A at 12V contact rating, the 5-terminal SPST layout, and the 36 x 20 mm mounting size before purchase or installation.
