Narva Sealed Rocker Switch Momentary On/off/momentary On Dpdt 12V/24V Blue LED 63173BL

The Narva sealed rocker switch, part number 63173BL, is a momentary on/off/momentary on DPDT switch designed for 12V or 24V systems. It is rated at 20A at 12V and 10A at 24V, with a blue LED for on illumination and a 7-terminal layout.

This switch uses a push fit design with push on terminals and a mounting opening of 37.5 x 21mm. The listed mount length is 37.5mm, which is a useful check when matching the switch to an existing dash, panel, or switch housing.

As a sealed rocker switch with a 3-position action, it suits installations where a momentary function is needed in both directions with an off position in the centre. The unit is sold each and carries a one year warranty.

Application and Buying Notes

Before ordering, confirm the panel cut-out is 37.5 x 21mm and that the available depth suits a switch with a 37.5mm mount length. The 7-terminal arrangement and DPDT design need to match the wiring layout already in the vehicle or equipment.

The current rating is 20A at 12V and 10A at 24V, so the switch should be matched to the circuit demand rather than assumed to suit all accessories. If the load is close to the rated current, it is wise to check the full circuit design, including wiring size, protection, and operating conditions.

The momentary on/off/momentary on action is important. This is not a standard maintained two-position rocker, so it should only be selected where spring-return operation is required in both directions. Confirm the application needs a 3-position switch with a centre off position before fitting.

The blue LED on illumination helps indicate switch status, but illumination style does not replace proper wiring verification. Make sure the terminal layout and backlighting arrangement suit the intended installation, especially where the switch is being added to an existing dashboard or switch bank.

For a clean replacement, compare the existing switch markings, terminal count, and part number 63173BL before purchase. That is the safest way to avoid ordering a switch that looks similar but uses a different action, terminal configuration, or cut-out size.

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 63173BL 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.

Narva Sealed Rocker Switch Momentary On/Off/Momentary On DPDT 12V/24V Blue LED (Contacts Rated 20A @ 12V). Part number 63173BL 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 63173BL, 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 the part number 63173BL, the 37.5 x 21mm mounting opening, the 7-terminal DPDT layout, and the momentary on/off/momentary on switch action against your existing application.
