Narva Rocker Switch Off/on Spst Amber LED 30A 12V Part No. 62057BL

The Narva Rocker Switch Off/On SPST Amber LED is a 12V switch rated at 30A, with a 12mm mounting diameter and 3 terminals for push-terminal wiring. It is identified by Part No. 62057BL and is supplied as an illuminated rocker switch with amber lamp colour.

This is a single-pole single-throw switch with an On-Off action and 2 positions. The contacts are rated for 30A at 12V only, so it needs to be matched carefully to the circuit voltage and current demand before installation.

For buyers replacing a worn rocker or adding a simple switched control to a 12V automotive electrical circuit, the key checks are the 12mm mounting opening, the 3mm mounting length, and the 3-terminal arrangement. Those details matter just as much as the switch style itself.

Narva lists this item as part of its auto electrical accessories range, with a one-year warranty and a very light unit weight of 0.015kg. If you are matching an existing panel switch, the part number 62057BL and the 30A/12V rating are the most useful identifiers to compare.

Application and Buying Notes

Because this switch is rated at 30A for use at 12V only, it should be used where the circuit requirements suit that rating. It is not appropriate to assume compatibility from the switch style alone; the voltage, current draw, and terminal arrangement all need to line up with the existing setup.

The mounting opening is 12mm diameter, which is one of the main installation checks for dashboard, console, or accessory panels. If the panel hole is larger or smaller than 12mm, the switch may not seat correctly or may need a different mounting solution.

With 3 terminals and push terminals, this Narva switch suits wiring setups that are designed for that connection style. Before ordering, compare the existing switch body, terminal count, and wiring layout with the 62057BL part number rather than relying on the appearance of the face only.

The amber illumination is part of the switch specification, so it may be useful where a visible status light is preferred. Even so, the key buying decision remains the electrical match: 12V system compatibility, 30A contact rating, and a physical fit at the 12mm mounting opening.

If you are replacing an existing switch, confirm the old part number, mounting diameter, and terminal count before installation. A close visual match is not enough on its own when working with vehicle electrical controls, especially where panel cut-outs and circuit loads are involved.

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 62057BL 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. 62057BL, Brand NARVA, Description Narva Rocker Switch Off/On SPST Amber LED (Contacts Rated 30A @ 12V), Number of Terminals 3, Switch Action On - Off - SPST, Lamp Colour/s Amber, Mount Length 3mm, Number of Positions 2, Switch Illumination Illuminated.

Narva Rocker Switch Off/On SPST Amber LED (Contacts Rated 30A @ 12V). Part number 62057BL should be checked first. Listed voltage is 12. Listed output rating is 30. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 62057BL, 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 30 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking Part No. 62057BL, 12V operating voltage, 30A rating, 12mm mounting diameter, and the 3-terminal push-terminal layout against the vehicle or panel application before purchase.
