Narva Sealed Rocker Switch Off/on Spdt 12V Blue Illuminated 20A Part No. 63132BL

The Narva Sealed Rocker Switch Off/On SPDT 12V is a compact electrical switch with a 20A contact rating at 12V, blue illumination, and a driving lights symbol. It is identified by part number 63132BL and is supplied as a single switch unit.

This switch uses an Off - On action, a 1 pole layout, and 5 terminals. The mounting opening is 37.5mm x 21mm, with a stated mount length of 37.5mm, so it needs to be checked against the panel opening before fitting.

The switch is described as sealed and uses push on terminals. It includes ‘Dash Light’ and ‘On’ illumination, which is useful where you want the switch position to be visible in low light and the panel layout to stay consistent with the vehicle interior.

Application and Buying Notes

Before buying, check the panel opening carefully. The mounting opening for this Narva switch is 37.5mm x 21mm, and the mount length is listed as 37.5mm. If the opening is smaller, shaped differently, or already used by another switch style, it may not seat correctly without modification.

The electrical rating matters as much as the physical size. This unit is rated at 20A for use at 12V only, so it should only be matched to a circuit that stays within that rating. If the circuit draw is close to the limit, allow suitable margin and confirm the wiring and fuse protection are appropriate for the application.

The switch is SPDT with 5 terminals and push on terminals, so the existing wiring arrangement needs to suit that configuration. If you are replacing a switch, compare the terminal count, switch action, and layout before ordering, especially where the original switch has a different contact arrangement or illumination style.

The blue illuminated finish and driving lights symbol help identify the switch location and function, but they do not confirm compatibility on their own. The most reliable checks are the part number 63132BL, the 12V rating, the 20A rating, and the 37.5mm x 21mm mounting opening. If any of those details differ from your vehicle or panel setup, confirm the application before 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 63132BL 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.

For part number 63132BL, 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 fitment by checking part number 63132BL, the 12V 20A rating, the 5-terminal SPDT layout, and the 37.5mm x 21mm mounting opening against your existing switch and panel before ordering.
