Narva Sealed Rocker Switch Off/on Spst 12V Green Illuminated 20A Part No. 63124BL

The Narva Sealed Rocker Switch Off/On SPST is a 12V switch with green illumination and contacts rated at 20A at 12V only. It is listed as a rocker switch with 2 positions, 1 pole, and 5 terminals, making it a straightforward option where a sealed, illuminated dashboard-style switch is required.

This unit uses a push fit design with push on terminals and requires a mounting opening of 37.5 x 21mm. The mount length is 37.5mm, so checking the cut-out before ordering is important. The part number is 63124BL, which is the best reference to confirm you are selecting the correct switch variant.

Illumination is described as both 'Dash light' and 'On' illumination, with green lamp colour. That makes it suitable where a visible switched indicator is needed, but the electrical rating remains specific: 20A at 12V only. It is sold as each and carries a one year warranty.

Application and Buying Notes

Before buying, confirm the switch cut-out in your dash or panel matches the stated mounting opening of 37.5 x 21mm. The mount length is listed as 37.5mm, so the panel thickness and available space should also be checked against the installation location. A switch that is close in appearance can still differ in cut-out size, terminal layout, or illumination style.

The electrical rating is limited to 20A at 12V only, so it is important to match the switch to the load it will control. This switch is an SPST off/on design with 2 positions and 1 pole, which suits simple single-circuit switching rather than multi-function control. If your application needs a different switching action, more poles, or a different voltage rating, this part would not be the right match.

The switch has 5 terminals and push on terminals, so wiring access and terminal style should be checked before installation. The green illumination includes both 'dash light' and 'on' indication, which is useful when you want the switch to be visible in low light and show operating status. If your existing switch has a different lamp colour, terminal count, or body shape, compare those details carefully to the 63124BL part number 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 63124BL 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 SPST 12V Green Illuminated (Contacts Rated 20A @ 12V). Part number 63124BL 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 63124BL, 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 the part number 63124BL, the 12V / 20A rating, the SPST off/on action, and the 37.5 x 21mm mounting opening with your vehicle or panel application.
