Narva Sealed Rocker Switch Off/on Spdt 12/24V Blue LED Illuminated Nav Lights Symbol Part No. 63256BL

The Narva Sealed Rocker Switch is an Off/On SPDT switch designed for 12 to 24V systems, with blue LED illumination and a nav lights symbol on the face. It is listed with contact ratings of 20A at 12V and 10A at 24V, making the electrical rating one of the first checks for any installation.

This switch uses a push fit design with push on terminals and a mounting opening of 37.5 x 21mm. The stated part number is 63256BL, and the unit is sold each, which helps when matching an existing switch opening or replacing a single control rather than a full panel assembly.

Illumination is provided for both 'Dash light' and 'On' positions, which can make the switch easier to identify in low light conditions. As with any sealed rocker switch, the important buying checks are the opening size, terminal style, system voltage, and the current draw of the circuit it will control.

Application and Buying Notes

Before ordering, confirm that your dash or control panel has a 37.5 x 21mm mounting opening. That measurement is one of the most useful physical checks because a rocker switch can look suitable but still fail to seat correctly if the aperture is different by only a few millimetres.

The electrical rating also matters. This switch is listed at 20A on a 12V system and 10A on a 24V system, so the circuit you plan to control should sit within those limits. If the load is higher, a relay or a different switch arrangement may be required rather than asking the switch to carry more current than it is rated for.

The terminal style is push on, so the existing wiring needs to suit push on terminals. If you are replacing an original switch, compare the connector style, terminal layout, and whether the existing wiring has enough reach and support once the switch is fitted into the panel.

The blue LED and 'Dash light' / 'On' illumination are useful for visibility, but they do not remove the need to verify the symbol orientation and the way the switch is intended to function in your setup. The switch action is Off - On with SPDT configuration, so it should only be used where that switching arrangement matches the circuit design.

If you are replacing an existing Narva switch, the part number 63256BL is the clearest reference to compare. Part number matching is often the safest way to confirm you are buying the same style and function, especially when the vehicle or equipment application is not specifically listed.

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 63256BL 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 12/24V Blue LED Illuminated Nav Lights Symbol (Contacts Rated 20A @ 12V). Part number 63256BL should be checked first. Listed voltage is 12 to 24. Listed output rating is 20A @ 12V/10A @24V. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 63256BL, 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 to 24 and output 20A @ 12V/10A @24V 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 checking the part number 63256BL, the 37.5 x 21mm mounting opening, the push on terminal style, and the 12 to 24V electrical requirements before purchase. If your existing switch or circuit details differ, do not assume it will be a direct replacement.
