Narva Rocker Switch Off/on Spst Red LED 20A 12V Part No. 62039BL

The Narva Rocker Switch Off/On SPST Red LED is a 12V switch with contacts rated at 20A and a 30A power rating listed. It is a 1-pole, 2-position rocker switch with 3 terminals and a 20mm mounting opening, suited to tidy panel mounting where a compact illuminated switch is needed.

It uses a red LED illumination and is described as IP65 rated, with a push fit design, push on terminals and a waterproof neoprene boot. The switch weighs 0.01kg and is sold as each, with Narva part number 62039BL.

For buyers replacing or adding an automotive control switch, the important checks are the 12V electrical system, the 20mm mounting diameter, and the terminal count. The switch action is On - Off - SPST, so it is intended for a simple single circuit control arrangement rather than a multi-circuit setup.

Application and Buying Notes

Before ordering, confirm the switch is going into a 12V circuit and that your panel has a 20mm mounting opening. The listed mount diameter is 20mm, and the switch uses a push fit design, so the physical opening and panel thickness need to be checked carefully before installation.

The electrical side also matters. This switch is described as SPST with 3 terminals, so it suits a simple on/off circuit rather than a changeover or multi-function control. The contact rating is 20A at 12V, while the power rating is listed as 30A, so it should only be used within the limits of the application it is fitted to.

Illumination is by red LED, which is useful where the driver wants a visible switch status at night or in low light. Because the switch is listed as IP65 rated and supplied with a waterproof neoprene boot, it is a sensible choice where splash resistance is important, but it still needs to be mounted and wired properly to suit the vehicle or accessory setup.

If you are replacing an existing switch, the safest approach is to match the part number 62039BL and compare the physical details, including the 20mm opening, 3 terminals and rocker style. That is more reliable than relying on appearance alone, especially where dash apertures and connector layouts vary between vehicles and accessory panels.

This switch is sold as each and carries a one year warranty. As with any 12V electrical accessory, the final decision should be based on the circuit load, the type of control required and the available mounting space, not just the illuminated face or rocker shape.

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 62039BL 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.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 30, Voltage 12, Mount Diameter 20mm, Number of Poles 1, Switch Type Rocker, Weight 0.01kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 62039BL, Brand NARVA, Description Narva Rocker Switch Off/On SPST Red LED (Contacts Rated 20A @ 12V), Number of Terminals 3, Switch Action On - Off - SPST, Lamp Colour/s Red, Mount Length 3mm, Number of Positions 2, Switch Illumination Illuminated.

Narva Rocker Switch Off/On SPST Red LED (Contacts Rated 20A @ 12V). Part number 62039BL should be checked first. Listed voltage is 12. Listed output rating is 30. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 62039BL, 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 30 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by checking the Narva part number 62039BL, the 20mm mounting diameter, the 3-terminal SPST layout and the requirement for a 12V circuit before purchase.
