Narva Sealed Rocker Switch On/on Dpdt 12/24V Red LED 63166BL

The Narva Sealed Rocker Switch is a 2-position On/On DPDT switch designed for 12V or 24V vehicle electrical systems. It carries a 20A rating at 12V and 10A at 24V, with red LED illumination and a sealed rocker style suited to practical automotive electrical use.

This switch uses 7 terminals and a push fit design with push on terminals, which makes the connection style straightforward where the correct wiring layout has been planned. The mounting opening is 37.5 x 21mm, so checking the panel cut-out before ordering is essential.

Identified by part number 63166BL, this Narva switch is supplied as a single piece and sits in the auto electrical accessories group. It is a useful option where an illuminated DPDT On/On rocker is required and the installation space matches the stated 37.5 x 21mm opening.

Application and Buying Notes

Before buying, check that your panel can accept a 37.5 x 21mm mounting opening. That cut-out size is one of the most important checks for this Narva sealed rocker switch, because the switch style and terminal layout are only suitable when the panel space and wiring access match.

The 20A rating at 12V and 10A rating at 24V are important limits to respect. If your application draws close to those values, confirm the load requirements carefully before installation. The switch is DPDT with 2 poles, 7 terminals, and an On/On action, so it should only be used where that switching arrangement is appropriate.

Because the terminals are push fit with push on terminals, the wiring connectors need to suit that style. It is worth checking clearance behind the panel, the route of the wiring, and whether the illuminated red LED function is suitable for the way the switch will be used in the vehicle or equipment.

If you are replacing an existing switch, matching part number 63166BL is the most direct reference point available. Where the original switch differs in terminal count, panel cut-out, voltage range, or switching action, compare those details before purchase so the replacement can be assessed properly.

This switch is listed as suitable for 12 or 24 volt use, but the current rating changes with system voltage. That matters when you are choosing a switch for accessories, control circuits, or auxiliary equipment, because the electrical load must stay within the stated rating.

The warranty is one year, and the item is supplied individually. If the application is part of a larger control panel build, confirm whether you need one switch or several, and check that the red illumination suits the rest of the panel layout and visibility requirements.

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 63166BL 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 On/On DPDT 12/24V Red LED (Contacts Rated 20A @ 12V). Part number 63166BL should be checked first. Listed voltage is 12 or 24. Listed output rating is 20A @ 12V. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 63166BL, 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 or 24 and output 20A @ 12V 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 matching part number 63166BL, the On/On DPDT switching action, the 7-terminal layout, and the 37.5 x 21mm mounting opening against your existing switch or panel requirements before ordering.
