Narva Rocker Switch Off/on Dpst Green LED 20A 12V Part No. 63027BL

The Narva Rocker Switch Off/On DPST Green LED is a 12V switch with contacts rated to 20A, supplied under part number 63027BL. It uses a rocker-style on-off action with DPST switching, a green illuminated lamp, and a front fog light symbol on the face.

This unit is sold as a single switch and uses 4 terminals with 6.3mm push on blade connections. The mounting opening is 34.5mm x 20mm, and the listed mount length is 3mm, so the panel cut-out and space behind the dash should be checked before purchase.

With a one year warranty and a weight of 0.02kg, this Narva switch suits buyers looking for a compact, clearly identified control switch for a 12V vehicle electrical setup. The key points to confirm are the 12V system, the 20A current rating, the 4-terminal DPST layout, and the 34.5mm x 20mm mounting opening.

Application and Buying Notes

Before ordering, check that your vehicle or accessory circuit is operating on 12V and that the load does not exceed the 20A contact rating. The switch is described as a DPST rocker with 4 terminals, so it needs to suit the circuit design you are working with rather than a simple single-pole switch.

The mounting opening is 34.5mm x 20mm, which is one of the most important measurements to confirm on the dash, console, or switch panel. The listed mount length is 3mm, so allowance behind the panel should also be checked if the installation space is tight.

This switch uses 6.3mm push on blade terminals, so the wiring connectors need to match that terminal size. If your existing wiring uses a different terminal style, allow for suitable adapters or re-termination before fitting.

The front fog light symbol may make this a practical choice where an illuminated fog light-style switch is wanted, but the symbol alone does not confirm vehicle-specific compatibility. Always compare the part number 63027BL, the terminal count, and the cut-out size against the original switch or the intended installation.

Because the switch is illuminated with a green lamp colour, it can suit dash layouts where a lit control is preferred. Even so, the electrical function still needs to be matched correctly: 12V only, 20A rating, DPST operation, and a 4-terminal arrangement are the main checkpoints.

If you are replacing an existing switch, match the physical dimensions and electrical specification as closely as possible. The safest approach is to verify the panel opening, the terminal layout, and the circuit requirements before purchase, rather than relying on appearance alone.

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 63027BL 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.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 20, Voltage 12, Mount Length 3mm, Number of Positions 2, Item Type Light Switch, Weight 0.02kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 63027BL, Brand NARVA, Description Narva Rocker Switch Off/On DPST Green LED (Contacts Rated 20A @ 12V), Number of Terminals 4, Switch Action On - Off - DPST, Lamp Colour/s Green, Number of Poles 2, Switch Type Rocker, Switch Illumination Illuminated.

Narva Rocker Switch Off/On DPST Green LED (Contacts Rated 20A @ 12V). Part number 63027BL 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 63027BL, 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 checking part number 63027BL, the 34.5mm x 20mm mounting opening, the 4-terminal DPST layout, and the 12V 20A rating against your existing switch or intended circuit.
