Narva Sealed Rocker Switch Off/on Spdt 12V Blue Illuminated Beacon Symbol 20A Part No. 63147BL

The Narva Sealed Rocker Switch is an Off/On SPDT switch rated at 20A at 12V only, with a blue illuminated beacon symbol and “dash light” and “on” illumination. It uses a push fit design with push on terminals and has 5 terminals, making it a compact electrical control option for suitable 12V applications.

This switch has a mounting opening of 37.5 x 21mm and a mount length of 37.5mm. The unit is listed as a rocker switch with 2 positions, 1 pole, and a switch action of Off - On. For buyers matching an existing panel opening, the 37.5 x 21mm cut-out is the main check point before ordering.

Narva identifies this item as part number 63147BL. It is sold as each, weighs 0.045kg, and carries a one year warranty. The combination of blue illumination, beacon symbol marking, and sealed rocker style makes it important to confirm both the electrical rating and the panel size before purchase.

Application and Buying Notes

Before buying, check the panel cut-out first. This Narva switch requires a mounting opening of 37.5 x 21mm and has a mount length of 37.5mm, so it needs to suit the existing dash or accessory panel opening exactly enough for a proper fit.

Electrical matching matters as much as the physical size. The switch is rated at 20A at 12V only, so it should only be used in applications that stay within that voltage and current rating. If the circuit draws more than 20A at 12V, this is not the correct choice.

The terminal layout is also worth confirming before installation. This is a 5-terminal, push fit design with push on terminals, so the wiring style must suit the vehicle or accessory being connected. A quick check of the existing switch wiring can save time and avoid unnecessary rework.

The illumination style is part of the identification as well. This model has blue illumination with both “dash light” and “on” illumination, plus a beacon symbol. If you are replacing an existing illuminated switch, compare the symbol, colour, and lighting behaviour rather than relying on the rocker shape alone.

This is a general-purpose switch listing rather than a vehicle-specific fitment listing. If you are unsure, confirm the existing part number 63147BL, the rocker format, the 37.5 x 21mm mounting opening, and the 12V 20A rating before placing the order.

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 63147BL 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.

Narva Sealed Rocker Switch Off/On SPDT 12V Blue Illuminated Beacon Symbol (Contacts Rated 20A @ 12V). Part number 63147BL 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 63147BL, 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: Confirm compatibility by matching part number 63147BL, the 12V 20A rating, the 5-terminal push fit layout, and the 37.5 x 21mm mounting opening against the vehicle or panel application.
