Narva Sealed Rocker Switch Off-momentary On Spst 12/24V Blue LED Part No. 63165BL

The Narva sealed rocker switch, part number 63165BL, is an Off-Momentary On SPST switch designed for 12V or 24V electrical systems. It is supplied as a rocker switch with blue illumination and is rated at 20A at 12V or 10A at 24V, making the electrical rating an important check before installation.

This switch uses a push fit design with push on terminals and has 5 terminals in total. The mounting opening is 37.5 x 21mm, with a stated mount length of 37.5mm. Those dimensions matter when you are matching an existing dash opening or planning a new panel installation.

Illumination is listed as both ‘Dash light’ and ‘On’ illumination, with a blue lamp colour. For buyers replacing an existing switch, the key identifiers to confirm are the switch action, the terminal count, the mounting opening, and the part number 63165BL.

Application and Buying Notes

Before ordering, confirm that your vehicle or panel uses an Off-Momentary On SPST switch layout and that the available opening is 37.5 x 21mm. The mounting size is one of the most important checks here, because a correct electrical rating is not enough if the panel cut-out does not suit the switch body.

Also check the terminal arrangement. This switch has 5 terminals and uses push on terminals, so it is best matched to an installation that already accepts that style of connection. If you are replacing an existing switch, compare the rear terminal layout, the switch action, and the illumination function against the old unit before fitting.

The voltage and current rating should be matched to the application. Narva lists this switch at 20A at 12V and 10A at 24V. That means it should only be used within those stated limits, and you should allow for the actual circuit load rather than assuming the switch suits every accessory application.

The blue LED illumination and ‘Dash light’ and ‘On’ illumination functions are useful if you want the switch to be visible in a dark cabin or to indicate when the circuit is active. Even so, illumination style should be checked against the vehicle interior or panel layout so the finished installation meets your expectations.

If you are unsure about compatibility, compare the part number 63165BL with the original switch details and measure the panel opening before purchase. The listed dimensions, terminal count, and switch action are the best practical checkpoints for confirming whether this switch is the right replacement or the right switch for a custom installation.

This item is supplied as an each, with a one year warranty and a listed weight of 0.04kg. Those details are useful for handling, freight planning, and confirming that you are comparing like-for-like when checking replacement parts.

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 63165BL 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.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 20A @ 12V, Voltage 12 or 24, Mount Length 37.5mm, Number of Positions 2, Switch Illumination Illuminated, Product Group 2 FUSES BREAKERS RELAYS SWITCHES.

Narva Sealed Rocker Switch Off/Momentary On SPST 12/24V Blue LED (Contacts Rated 20A @ 12V). Part number 63165BL 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 63165BL, 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 fitment by matching part number 63165BL, switch action, terminal count, illumination type, and the 37.5 x 21mm mounting opening to your existing application before purchase.
