Narva Sealed Rocker Switch Off/on/on Dpdt 20A 12V Part No. 63108BL

The Narva Sealed Rocker Switch Off/On/On DPDT is a 12V switch with contacts rated to 20A at 12V and 10A at 24V. It is supplied as a non-illuminated rocker switch with Off - On - On - DPDT action, making it a straightforward control option where a sealed switching layout is required.

This switch uses push-on terminals and has 4 terminals in total. The mounting opening is 37.5mm x 21mm, with a stated mount length of 37.5mm. If you are replacing an existing rocker switch, the opening size, terminal arrangement, and switch action are the main details to confirm before ordering.

The listed part number is 63108BL and the brand is Narva. It weighs 0.04kg and is sold as each. The one year warranty is useful for general buying confidence, but the practical check remains the same: confirm the 20A 12V rating, the DPDT configuration, and the physical mounting size match your application.

Application and Buying Notes

Before buying, check the existing switch opening and terminal layout. This Narva unit uses a 37.5mm x 21mm mounting opening and push-on terminals, so it is best matched to an installation that already accepts that size and style of connection. The part number 63108BL is the clearest reference to compare against a replacement switch.

The electrical rating also needs to suit the circuit. This switch is rated at 20A at 12V and 10A at 24V, so it should only be used where those figures align with the load and system voltage. Matching the switch action is just as important: this unit is Off - On - On with DPDT contacts and 2 poles.

Because it is non-illuminated, there is no lamp function to allow for in the panel wiring. If your original switch has a light, this rocker will not duplicate that feature. Check the 4-terminal layout carefully, as a DPDT switch is wired differently from a single-pole switch and should only be fitted where the circuit design calls for it.

For a clean replacement, compare the shape, mounting size, terminal style, and operating positions against the switch already in the vehicle or equipment. The listed 37.5mm mount length and 0.04kg weight are useful reference points when checking the panel opening and confirming you are not dealing with a different style of rocker assembly.

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 63108BL 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/On DPDT (Contacts Rated 20A @12V). Part number 63108BL 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 63108BL, 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 compatibility by matching the part number 63108BL, the 37.5mm x 21mm mounting opening, the 4-terminal push-on layout, and the Off - On - On DPDT switch action before purchase.
