Narva Heavy Duty Rocker Switch On/off/on Dpdt 25A 12V 63043BL

The Narva Heavy Duty Rocker Switch is an On/Off/On DPDT switch rated at 25A at 12V, with 12.5A at 24V. It uses a 6 terminal, 2 pole arrangement and is supplied as part number 63043BL. For buyers matching an existing switch panel, the mounting opening is 37.5 x 21mm, so the cut-out size is one of the first checks before ordering.

This is a non-illuminated rocker switch with a push fit design and push on terminals. The switch action is On - Off - On - DPDT, which gives three positions and a centre off position. That makes it suitable where a straightforward maintained control layout is needed, provided the electrical load and terminal layout suit the application.

The listed contact rating is 20A at 12V, while the overall power rating is 25A at 12V. For a 12V vehicle or accessory setup, those figures matter when comparing the switch to the current draw of the circuit. Weight is listed at 0.03kg, and the unit is supplied individually as each in blister pack form.

Application and Buying Notes

Before buying, compare the part number 63043BL and the physical format of your existing switch. The key installation dimension provided here is the 37.5 x 21mm mounting opening, which needs to match the panel cut-out or mounting space in your vehicle or accessory panel.

Because this is a 2 pole, 6 terminal On - Off - On DPDT rocker switch, the wiring arrangement should be checked against the circuit you are replacing or building. DPDT switching is not the same as a single pole switch, so the terminal count and switching action need to suit the application before installation.

The stated ratings are 25A at 12V and 12.5A at 24V, with contacts rated 20A at 12V. Those figures are important when assessing whether the switch is appropriate for the intended circuit load. As with any electrical part, matching the voltage, terminal layout and panel opening is more important than choosing by appearance alone.

This switch is non illuminated, so it will not provide an internal lamp or backlight. If you are replacing a lit switch, confirm whether the original unit used illumination, as the lamp colour is listed as not applicable here. The unit is sold each, and comes in blister pack form.

For a clean result, check the depth and access behind the panel as well as the front cut-out. A push fit design with push on terminals can be convenient in suitable panels, but only if the connectors, space and wiring route are compatible with your setup. The one-year warranty applies to the product as supplied.

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 63043BL 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) 25, Voltage 12, Number of Poles 2, Switch Type Rocker, Weight 0.03kg, Product Group 1 AUTO ELEC ACCESSORIES, Part No. 63043BL.

Additional published details for cross-checking include Brand NARVA, Description Narva Heavy Duty Rocker Switch On/Off/On DPDT (Contacts Rated 20A @ 12V), Number of Terminals 6, Switch Action On - Off - On - DPDT, Lamp Colour/s Not Applicable, Number of Positions 3, Switch Illumination Non Illuminated, Product Group 2 FUSES BREAKERS RELAYS SWITCHES.

Narva Heavy Duty Rocker Switch On/Off/On DPDT (Contacts Rated 20A @ 12V). Part number 63043BL should be checked first. Listed voltage is 12. Listed output rating is 25. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 63043BL, 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 25 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 fitment by matching part number 63043BL, the On - Off - On DPDT switch action, the 6 terminal layout, and the 37.5 x 21mm mounting opening before purchase.
