Narva Sealed Rocker Switch Off/momentary On Spst 20A 12V Part No. 63102BL

The Narva Sealed Rocker Switch is a 2-position switch with Off / Momentary On action and SPST contacts, rated at 20A at 12V. It is identified by Part No. 63102BL and is supplied as a single switch unit.

This switch uses push-on terminals and has a mounting opening of 37.5mm x 21mm, which makes the panel opening an important check before ordering. It is non-illuminated and has 2 terminals, so it suits straightforward switching applications where a sealed rocker layout is required.

At 0.04kg, it is a compact electrical accessory from Narva, backed by a one-year warranty. The stated current rating is 20A at 12V and 10A at 24V, so the system voltage and load should be matched to the published ratings before installation.

Application and Buying Notes

Before buying, check the part number 63102BL and compare the mounting opening against your panel cut-out. The required opening is 37.5mm x 21mm, so even a small difference in panel size can affect installation. The switch also uses push-on terminals, which means your wiring connectors need to suit that style of termination.

Electrical load is another key point. This Narva rocker switch is rated at 20A on a 12V system and 10A on a 24V system, so it should only be used within those limits. The SPST layout and 2-terminal design indicate a simple on/off-style control path with a momentary on function, so it is worth confirming that your application calls for Off - Momentary On operation rather than a maintained two-way switch.

Because the switch is non-illuminated, it will not provide built-in light indication. That may be suitable for some fit-outs, but if you need a visible status light, this model does not list illumination as a feature. The compact 0.04kg weight and sealed rocker style make it a tidy option for panel-based automotive electrical work where a clean, simple switch is needed.

If you are replacing an existing switch, compare the current rating, voltage rating, terminal style and panel opening before purchase. Matching the physical opening is just as important as matching the electrical rating, especially when working with a sealed rocker switch intended for neat dash or panel mounting.

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 63102BL 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/Momentary On SPST (Contacts Rated 20A @ 12V). Part number 63102BL 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 63102BL, 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 Part No. 63102BL, the 37.5mm x 21mm mounting opening, the 2-terminal SPST Off / Momentary On action, and the 20A at 12V / 10A at 24V ratings to your application before ordering.
