Narva Sealed Rocker Switch Momentary On/off/momentary On Dpdt 20A 12V Part No. 63110BL

The Narva Sealed Rocker Switch Part No. 63110BL is a 3-position momentary on/off/momentary on switch with DPDT contacts, rated at 20A at 12V and 10A at 24V. It is supplied as a non-illuminated rocker switch with 6 terminals and push on terminals for installation where a compact control switch is needed.

This switch has a mounting opening of 37.5mm x 21mm and a mount length of 37.5mm, so the panel cut-out needs to match those dimensions before purchase. The switch action is listed as Mom On - Off - Mom On - DPDT, which is important when the circuit needs a spring-return function rather than a latching on/off action.

Narva identifies this as a sealed rocker switch in the Fuses, Breakers, Relays, Switches product group. It weighs 0.04kg and carries a one year warranty. As with any electrical switch, the part number 63110BL and the mounting opening size are the main checkpoints for confirming it is the right unit for the job.

Application and Buying Notes

Before buying, confirm the application needs a 3-position momentary on/off/momentary on rocker with DPDT contacts. The 20A at 12V and 10A at 24V ratings are important because the switch must suit both the circuit voltage and the electrical load it will carry.

Check the panel opening carefully. This switch requires a mounting opening of 37.5mm x 21mm and has a mount length of 37.5mm, so the physical cut-out must match rather than being estimated from a similar-looking switch.

The 6 terminal layout and push on terminals suit installations that are already configured for this style of connection. If the wiring layout in the vehicle or equipment does not match a DPDT 6-terminal switch, it will need to be rechecked before fitting.

Because the switch is non illuminated and lamp colour is not applicable, it is intended for applications where backlighting is not required. That matters if you are replacing a lighted switch or need the switch to match an illuminated dash panel.

The part number 63110BL is the safest way to cross-check the item when replacing a Narva switch or comparing alternatives. If the existing unit has a different action, different terminal count, or a different cut-out size, do not assume this one will substitute directly.

For best results, compare the circuit function, the terminal arrangement, and the panel opening dimensions together. A switch can look similar externally while having a different internal action or terminal setup, so the electrical and physical details both need to line up.

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 63110BL 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.

Additional published details for cross-checking include Part No. 63110BL, Brand NARVA, Description Narva Sealed Rocker Switch Momentary On/Off/Momentary On DPDT (Contacts Rated 20A @ 12V), Number of Terminals 6, Switch Action Mom On - Off - Mom On - DPDT, Lamp Colour/s Not Applicable, Number of Poles 2, Switch Type Rocker, Weight 0.04kg, Product Group 1 AUTO ELEC ACCESSORIES.

Narva Sealed Rocker Switch Momentary On/Off/Momentary On DPDT (Contacts Rated 20A @ 12V). Part number 63110BL 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 63110BL, 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.

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 matching part number 63110BL, the 37.5mm x 21mm mounting opening, the 6-terminal DPDT layout, and the momentary on/off/momentary on switch action before ordering.
