Narva Heavy Duty Toggle Switch Off/on Spst 50A 12V Part No. 60078BL

The Narva Heavy Duty Toggle Switch is an off/on SPST switch with contacts rated at 50A @ 12V, making it a straightforward option for a 12V panel-mounted control setup where a simple two-position switching action is required. It uses a 12mm mounting opening and a chrome toggle with screw terminals for installation.

This is a non-illuminated switch with 2 terminals and 1 pole, listed as On - Off - SPST with 2 positions. The mounting length is 3mm, and the unit weight is 0.056kg. For buyers matching by part reference, the part number is 60078BL.

It is sold as an each item and carries a one year warranty. The voltage and current ratings are important here: 50A at 12V, and 25A at 24V. Those figures should always be checked against the circuit requirements before fitting to any vehicle or accessory system.

Application and Buying Notes

Before ordering, confirm the switch will suit the panel opening and circuit load. The key checks here are the 12mm mount diameter, the 3mm mount length, and the electrical rating of 50A at 12V or 25A at 24V. If your application needs a different bezel size, a different terminal layout, or illumination, this model may not be the right match.

The switch uses 2 screw terminals and an SPST on/off action, so it is intended for simple single-circuit control rather than multi-function switching. That makes the part number 60078BL and the listed switch action the safest references when comparing against a replacement or planning a new installation.

Because this is a heavy duty toggle switch, it should still be matched carefully to the rest of the circuit, including wire size, fuse protection, and the actual load draw of the accessory being controlled. The current rating is a useful guide, but it does not replace proper circuit design or vehicle-specific checks.

If you are replacing an existing switch, compare the physical mount, terminal count, and the position of the toggle in the off and on states. The non-illuminated design means there is no lamp function to factor in, and the lamp colour field is not applicable. Those details matter when you are trying to match an original panel layout or dash arrangement.

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 60078BL 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) 50, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Weight 0.056kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 60078BL, Brand NARVA, Description Narva Heavy Duty Toggle Switch Off/On SPST (Contacts Rated 50A @ 12V), Number of Terminals 2, Switch Action On - Off - SPST, Lamp Colour/s Not Applicable, Mount Length 3mm, Number of Positions 2, Switch Illumination Non Illuminated.

Narva Heavy Duty Toggle Switch Off/On SPST (Contacts Rated 50A @ 12V). Part number 60078BL should be checked first. Listed voltage is 12. Listed output rating is 50. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 60078BL, 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 50 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.

Compatibility note: Confirm compatibility by comparing part number 60078BL, the 12mm mounting opening, the 2-terminal SPST layout, and the 50A @ 12V rating with your existing switch and circuit requirements before purchase.
