Narva Sealed Rocker Switch Off/on Spst 20A 12V Part No. 63100BL

The Narva Sealed Rocker Switch Off/On SPST is a 2-position switch rated at 20A at 12V and 10A at 24V. It uses a sealed rocker design with push on terminals and a non-illuminated face, making it a straightforward control option where a simple Off/On function is required.

This switch is identified by Part No. 63100BL and has a mounting opening of 37.5mm x 21mm. With 2 terminals and a single pole SPST layout, it suits basic circuit control tasks where the wiring and mounting dimensions need to be checked before purchase.

Narva lists this switch as an auto electrical accessory with a one year warranty. At 0.04kg each, it is a compact component, but the installation still depends on matching the 37.5mm x 21mm panel opening, the 2-terminal arrangement, and the intended 12V or 24V electrical load.

Application and Buying Notes

Before ordering, confirm the panel opening is 37.5mm x 21mm and that your installation suits a 2-terminal SPST switch with an Off/On action. Those dimensions and the terminal count are the key checks for this Narva 63100BL switch, especially where an existing rocker switch is being replaced.

The electrical rating matters just as much as the hole size. This switch is rated at 20A on 12V circuits and 10A on 24V circuits, so it should only be used within those limits. If the circuit load is higher, or if the application requires a different switching arrangement, this part is not the right match.

Because the switch is non-illuminated and the lamp colour is not applicable, it is best suited to jobs where a plain, functional rocker is needed rather than an illuminated control. The push on terminals also mean the connector style needs to suit the wiring already in the vehicle or panel setup.

The listed 0.04kg weight is light, but installation quality still comes down to the physical fit and wiring layout. If you are replacing an existing switch, compare the old unit’s mounting opening, terminal style, and switch action against the 63100BL details before you commit to the 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 63100BL 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.

Additional published details for cross-checking include Part No. 63100BL, Brand NARVA, Description Narva Sealed Rocker Switch Off/On SPST (Contacts Rated 20A @ 12V), Number of Terminals 2, Switch Action Off - On, Lamp Colour/s Not Applicable, Number of Poles 1, Switch Type Rocker, Switch Illumination Non Illuminated.

Narva Sealed Rocker Switch Off/On SPST (Contacts Rated 20A @ 12V). Part number 63100BL 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 63100BL, 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.

Compatibility note: Confirm compatibility by matching the part number 63100BL, the 37.5mm x 21mm mounting opening, the 2-terminal SPST Off/On layout, and the 12V or 24V electrical rating before ordering.
