Narva Sealed Rocker Switch Off/on/on Dpdt 12/24V Blue LED 63171BL

The Narva sealed rocker switch, part number 63171BL, is an Off/On/On DPDT switch designed for 12V or 24V systems. It has 6 terminals, a 3-position action, and a blue illuminated lamp arrangement with both “dash light” and “on” illumination.

It is rated at 20A at 12V and 10A at 24V, with a mounting opening of 37.5 x 21mm and a mount length of 37.5mm. The switch uses a push fit design with push on terminals, which is a useful detail to check before ordering if you are matching an existing panel cut-out or wiring layout.

This is a practical choice for installations where a sealed rocker style switch is needed and the electrical load sits within the stated current rating. The switch is sold each and carries a one year warranty.

Application and Buying Notes

Before buying, compare the part number 63171BL and the switch action Off - On - On - DPDT with the switch you are replacing. The 6-terminal layout and 2-pole, 3-position configuration are the key electrical checkpoints, especially if the existing switch uses a different terminal arrangement or only a single pole.

Check the mounting opening carefully against the stated 37.5 x 21mm panel cut-out. The listed mount length is 37.5mm, so the switch is best suited to panels that can accept that size without forcing the body or trimming the bezel area beyond what is already there.

The current rating matters just as much as the physical size. This switch is rated at 20A at 12V and 10A at 24V, so any connected circuit should stay within those limits. If the circuit load is higher, or if the existing application is outside 12V or 24V, it is not the right match.

The blue lamp colour and dual illumination function, described as “dash light” and “on” illumination, are useful if you want the switch to be visible in low light. If you are replacing a switch purely for function, the illumination details are still worth checking because they affect how the switch appears in the dashboard or control panel.

Because this is a sealed rocker style switch, it is worth confirming that the existing opening, terminal arrangement, and operating position all line up with your current setup. Using the part number, voltage rating, and mounting opening together is the safest way to check suitability before purchase.

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 63171BL 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/On DPDT 12/24V Blue LED (Contacts Rated 20A @ 12V). Part number 63171BL should be checked first. Listed voltage is 12 or 24. Listed output rating is 20A @ 12V. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 63171BL, 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 20A @ 12V 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 63171BL, the Off - On - On - DPDT switch action, the 12/24V rating, and the 37.5 x 21mm mounting opening against your existing switch and panel opening before ordering.
