Narva Sealed Rocker Switch Momentary On/off/momentary On Dpdt 12V/24V Red LED 63172BL

The Narva 63172BL sealed rocker switch is a momentary on/off/momentary on DPDT switch with red LED illumination, designed for 12V and 24V electrical systems. It carries a 20A rating at 12V and 10A at 24V, making the electrical load and supply voltage important checkpoints before fitting.

This is a 3-position rocker switch with 7 terminals and push on terminals for connection. The mounting opening is 37.5mm x 21mm, and the mount length is listed as 37.5mm, so it is important to confirm the panel cut-out and available depth before purchase.

Narva lists this switch as illuminated with red lamp colour/s and an 'On' illumination function. The switch action is Mom On - Off - Mom On - DPDT, which suits installations where a momentary switching action is required rather than a maintained on/off position alone.

Application and Buying Notes

Before ordering, confirm the switch style and panel opening against your existing installation. This Narva unit is a rocker switch with a 37.5mm x 21mm mounting opening and 37.5mm mount length, so the cut-out size and surrounding panel clearance need to suit the switch body as well as the face plate.

Electrical compatibility matters just as much as the physical opening. The contacts are rated at 20A at 12V and 10A at 24V, so the connected circuit should stay within those limits. If the application runs on 12V, the 20A rating is the relevant figure; for 24V systems, the listed 10A rating applies.

The switch action is Mom On - Off - Mom On - DPDT with 2 poles and 7 terminals, so wiring layout must match the intended function. It is not sensible to assume a simple on/off replacement will suit every loom or accessory setup, especially where momentary function or dual-pole switching is required.

The red LED illumination and 'On' illumination are useful for identifying switch status, but they do not remove the need to check the circuit design. The lamp colour is red, and the switch is listed as illuminated, so the visual behaviour should be considered when matching it to dashboard or accessory panel requirements.

Weight is listed at 0.045kg and the unit of measure is each. Those details are small, but they can still matter when comparing mounting hardware, panel load, or multiple-switch installations. The one year warranty is also listed for this part, which may be helpful when planning a replacement or custom fit-out.

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 63172BL 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 Red LED (Contacts Rated 20A @ 12V). Part number 63172BL 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 63172BL, 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.

Compatibility note: Confirm fitment by checking the part number 63172BL, the 37.5mm x 21mm mounting opening, the 3-position DPDT momentary action, and the 12V/24V current rating before ordering.
