Narva Sealed Rocker Switch Off/on Spdt 12V Blue Illuminated Fog Lights Symbol 20A Part No. 63134BL

The Narva sealed rocker switch is an Off/On SPDT switch rated at 20A for use at 12V only, with blue illumination and a fog lights symbol. It carries Part No. 63134BL and uses a 5-terminal layout with push-on terminals for straightforward installation in the correct 37.5mm x 21mm mounting opening.

This is a 1-pole rocker switch with 2 positions and a switch action of Off - On. The illumination includes both 'Dash Light' and 'On' indication, which helps identify switch status in a vehicle interior once fitted correctly.

At 0.04kg, it is a compact automotive electrical accessory designed for controlled switching applications where the mounting size, terminal style, voltage, and current rating all need to match the vehicle or accessory circuit. The sealed construction is part of the product type, which is important in vehicle environments where dust and moisture can be a concern.

Application and Buying Notes

Before buying, check that your application is designed for a 12V circuit and that the load will remain within the 20A rating. The switch is described as SPDT with an Off - On action, so it needs to suit the way the circuit is intended to operate rather than simply matching a similar-looking rocker.

Confirm the mounting opening is 37.5mm x 21mm and that there is enough panel space for the 37.5mm mount length. A switch can be the right electrical match but still be unsuitable if the panel cut-out or surrounding trim does not allow a proper fit.

The terminal layout matters as well. This unit has 5 push-on terminals, so the vehicle wiring or accessory loom needs to suit that style of connection. If your original switch uses a different terminal count, different terminal arrangement, or a different illumination format, it may not be a direct replacement.

The blue illumination and fog lights symbol are useful identifiers, but they do not confirm vehicle fitment on their own. Matching the part number 63134BL, the switch action, the 12V rating, and the mounting size is the most reliable way to assess suitability before purchase.

As with any electrical switch, the current draw of the connected circuit should be checked carefully. The 20A rating applies at 12V only, so it is important to verify the actual load and not rely only on the accessory name or the appearance of the switch.

If you are replacing a damaged or missing switch, compare the old unit against the part number, terminal count, illumination style, and cut-out size before ordering. That approach reduces the risk of having to modify the panel or rework the wiring after the part arrives.

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 63134BL 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.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 20, Voltage 12, Mount Length 37.5mm, Number of Positions 2, Item Type Switch, Weight 0.04kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 63134BL, Brand NARVA, Description Narva Sealed Rocker Switch Off/On SPDT 12V Blue Illuminated Fog Lights Symbol (Contacts Rated 20A @ 12V), Number of Terminals 5, Switch Action Off - On, Lamp Colour/s Blue, Number of Poles 1, Switch Type Rocker, Switch Illumination Illuminated.

Narva Sealed Rocker Switch Off/On SPDT 12V Blue Illuminated Fog Lights Symbol (Contacts Rated 20A @ 12V). Part number 63134BL 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 63134BL, 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.

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: Please confirm fitment by matching Part No. 63134BL, the 12V 20A rating, the 5-terminal push-on layout, and the 37.5mm x 21mm mounting opening with your existing switch and vehicle application before ordering.
