Application and Buying Notes

Before ordering, check the mounting opening carefully. This Narva switch is specified with a 37.5mm x 21mm mounting opening and a 37.5mm mount length, so it needs to suit the panel or housing you are fitting it into.

Electrical compatibility matters just as much as the physical size. The switch is rated at 20A at 12V only, so it should only be used where the circuit, wiring, and accessory load are suitable for that rating.

The SPDT format and 5-terminal layout are important if you are replacing an existing switch. If the original switch uses a different terminal count, pole arrangement, or action, it may not be a direct swap even if the opening is close.

The blue illumination and aux lights symbol are useful when you want the switch to be easy to identify at night. It has both ‘Dash Light’ and ‘On’ illumination, which may suit dashboard accessory control applications where visible status indication is wanted.

The listed weight is 0.04kg and the unit of measure is each, so this is a single switch supplied for individual use. If you are replacing an existing switch, the safest approach is to compare Part No. 63144BL and the physical dimensions against the old unit before buying.

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 63144BL 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.

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.

Compatibility note: Confirm compatibility by matching Part No. 63144BL, the 12V 20A rating, the 5-terminal SPDT layout, and the 37.5mm x 21mm mounting opening with your existing application before purchase.
