Narva Sealed Rocker Switch Off/on Spdt 12V Blue Illuminated Compressor Symbol 20A Part No. 63140BL

The Narva Sealed Rocker Switch is an Off/On SPDT switch rated at 20A at 12V only, with blue illumination and a compressor symbol on the rocker face. It is identified as part number 63140BL and uses a 5-terminal, 1-pole layout in a rocker-style switch body.

This switch uses a push fit design with push on terminals, and the mounting opening is listed at 37.5 x 21mm with a mount length of 37.5mm. Those dimensions matter when you are matching a replacement switch to an existing dash opening or planning a new installation in an auto electrical panel.

Illumination is described as both 'dash light' and 'on' illumination, which helps the switch remain visible in low light and gives a clear operating indication. The lamp colour is blue, and the unit is supplied as a single switch, sold each.

With a one year warranty and a listed weight of 0.04kg, this is a compact switch intended for vehicle electrical applications where the correct voltage, terminal style, and panel cut-out size need to be checked before purchase.

Application and Buying Notes

Before ordering, check the existing switch opening and mounting space carefully. The listed mounting opening is 37.5 x 21mm, and the mount length is 37.5mm, so the dash panel or control panel needs to suit those dimensions for a proper install.

Confirm the electrical setup as well. This switch is rated at 20A at 12V only, has 5 terminals, and uses an SPDT arrangement, so it should be matched to the circuit design and terminal layout required for the job.

The push fit design with push on terminals is useful when replacing a like-for-like switch, but it also means the terminal style must suit your existing wiring and connector arrangement. If the original switch uses a different terminal type or terminal count, do not assume this will be a direct replacement.

The compressor symbol and blue illumination make this a practical choice where the switch function needs to be clearly identified. The 'dash light' and 'on' illumination helps with visibility, but the switch still needs to be selected on the basis of fit, rating, and wiring compatibility rather than appearance alone.

If you are replacing an existing switch, compare the part number 63140BL, the Off/On action, and the panel cut-out size against the vehicle or accessory application before fitting. That is the safest way to avoid ordering a switch that looks suitable but does not match the opening or wiring.

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 63140BL 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 Off/On SPDT 12V Blue Illuminated Compressor Symbol (Contacts Rated 20A @ 12V). Part number 63140BL 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 63140BL, 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 63140BL, the 37.5 x 21mm mounting opening, the 5-terminal SPDT layout, and the 20A at 12V rating with your existing switch and application details before purchase.
