Narva Sealed Rocker Switch Off/on Spst 12V Amber Illuminated 20A Part No. 63122BL

The Narva Sealed Rocker Switch is an Off/On, SPST switch rated at 20A for use at 12V only, with amber illumination for both “Dash Light” and “On” indication. It suits applications where a compact illuminated rocker is needed and where the mounting opening can accommodate 37.5mm x 21mm.

This switch is supplied as a single unit and carries Narva part number 63122BL. It uses push on terminals and has 5 terminals in total, so checking your wiring setup before purchase is an important step. The switch is described as sealed, which is a practical feature for vehicle interiors and accessory panels where dust and general wear are a concern.

For buyers replacing an existing switch or planning a new accessory installation, the key details to confirm are the 12V operating requirement, the 20A amperage rating, the Off/On SPST action, and the mount length of 37.5mm. Those are the main checkpoints that determine whether the switch is suitable for the job.

Application and Buying Notes

Before ordering, compare the part number 63122BL and the physical mounting size of 37.5mm x 21mm with your existing switch panel or dash opening. A switch can look similar from the front but still differ in terminal layout, mounting size, or illumination arrangement, so the dimensions and terminal count matter as much as the appearance.

This Narva rocker is rated at 20A and is for 12V use only. That means the current draw of the circuit and the system voltage need to match the switch rating. If the accessory load exceeds 20A, or if the circuit is not a 12V system, this is not the right switch to fit.

The switch uses an SPST Off/On function with 2 positions and 1 pole. That suits a simple single-circuit control setup. The 5 push on terminals are also worth confirming against your existing wiring, as terminal style and count can affect how easily the switch integrates into the vehicle or accessory panel.

Illumination is amber, with separate “Dash Light” and “On” illumination noted. If you are replacing a matching illuminated rocker, check that the colour and lighting behaviour are the same as your current setup. For clean installation, allow for the 37.5mm mount length and make sure the opening size is suitable before starting the work.

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 63122BL 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 Off/On SPST 12V Amber Illuminated (Contacts Rated 20A @ 12V). Part number 63122BL 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 63122BL, 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 the Narva part number 63122BL, the 12V / 20A rating, the SPST Off/On action, the 5 terminal push on layout, and the 37.5mm x 21mm mounting opening against your existing application before purchase.
