Narva Sealed Rocker Switch Off/momentary On Spst 12/24V Red LED Part No. 63164BL

The Narva Sealed Rocker Switch is an illuminated SPST switch with an Off - Mom On - SPST action, designed for 12 or 24 volt use. It carries a 20A rating at 12V and 10A at 24V, with a red LED lamp and both 'dash light' and 'on' illumination.

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 listed mount length of 37.5mm, so the cut-out size needs to be checked carefully before fitting.

It is identified as Narva part number 63164BL and is supplied as a single each unit. The switch is sealed, making it a practical choice where a neat dash-mounted rocker switch is needed and the panel opening matches the stated dimensions.

Application and Buying Notes

Before ordering, compare the switch opening in your panel with the stated 37.5 x 21mm mounting opening. A rocker switch can look similar to others from the outside, but the cut-out size and terminal layout need to line up properly for a clean installation.

The electrical rating matters as much as the physical size. This switch is rated at 20A at 12V and 10A at 24V, so the load you plan to control should be checked against those figures rather than assumed from the switch style alone.

Because the switch is a 5 terminal, push fit design with push on terminals, it is best suited to installations that already use this style of connection. If your existing wiring uses a different terminal arrangement, you may need to rework the connections rather than expect a direct swap.

The Off - Mom On - SPST action is important to confirm before buying. Momentary operation is not the same as a standard latched on/off switch, and the correct action needs to match the accessory or circuit it is controlling.

Illumination is another point to verify. This Narva switch uses a red LED with both 'dash light' and 'on' illumination, which can be useful for visibility at night, but you should still confirm that the lighting behaviour suits your dash layout and intended use.

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 63164BL 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 or 24 and output 20A @ 12V should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking the part number 63164BL, the 37.5 x 21mm mounting opening, the 5 terminal layout, and the Off - Mom On - SPST switching action against your existing application before purchase.
