Application and Buying Notes

Before ordering, confirm the panel opening is 37.5mm x 21mm and allow for the 37.5mm mount length. That physical size is the most immediate check on whether the switch will suit your dash, console, switch panel, or other mounting position.

Electrical compatibility also needs to be checked carefully. This Narva switch is rated at 20A at 12V and 10A at 24V, so the connected circuit should sit within those limits. It is an SPST Off/On switch with one pole, two positions, and 5 terminals, so the existing wiring arrangement should suit that style of switch before fitting begins.

The push on terminals make installation straightforward where matching female terminals are already used, but terminal style is only one part of the job. The switch is illuminated with red lamp colouring and has both “Dash Light” and “On” illumination, so make sure that lighting function suits the intended application and the vehicle’s wiring setup.

Because fitment data is not provided for specific vehicle makes or models, the safest buying step is to compare the part number 63158BL, the switch action, the terminal count, and the mounting dimensions against the original switch or the opening you have available. That is the best way to avoid ordering a part that is electrically close but physically unsuitable.

The unit is sealed, but it still needs to be installed in a suitable location and wired correctly for the circuit it will control. If you are replacing an existing switch, match the function carefully: Off/On SPST, illuminated rocker, 12V or 24V supply, and the listed amperage rating are the key details that matter most here.

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 63158BL 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, Item Type Switch, Weight 0.04kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 63158BL, Brand NARVA, Description Narva Sealed Rocker Switch Off/On SPST 12V/24V Red LED (Contacts Rated 20A @ 12V), Number of Terminals 5, Switch Action Off - On - SPST, Lamp Colour/s Red, Number of Poles 1, Switch Type Rocker, Switch Illumination Illuminated.

Narva Sealed Rocker Switch Off/On SPST 12V/24V Red LED (Contacts Rated 20A @ 12V). Part number 63158BL 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 63158BL, 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 compatibility by checking part number 63158BL, the Off/On SPST switch action, 5 terminals, and the 37.5mm x 21mm mounting opening against your existing switch or panel requirements before purchase.
