Narva Metal Changeover Toggle Switch On/on Spdt 20A 12V 60057BL

The Narva Metal Changeover Toggle Switch is a panel-mount SPDT switch with an On - On action, silver contacts and screw terminals. It is rated at 20A at 12V and 10A at 24V, with a 12mm mounting opening and a 6mm mount length, making it a practical choice where a compact 2-position toggle is required.

This switch is supplied as part number 60057BL and is sold individually. It is non-illuminated, has 2 terminals, 1 pole and a metal toggle construction, with a listed weight of 0.03kg. For wiring work, the screw-terminal arrangement is useful where a secure mechanical connection is preferred over plug-in style terminals.

When selecting a replacement or planning an installation, the key details are the On - On SPDT action, the 12mm panel cut-out, and the current rating. The 20A rating at 12V and 10A at 24V should be matched to the circuit load and system voltage before fitment, especially on vehicle electrical accessories and control circuits.

Application and Buying Notes

Before ordering, confirm that your application needs an On - On SPDT switch and not an On - Off or momentary style. The switch action here is specifically On - On - SPDT, so it suits circuits where the toggle changes between two live positions rather than switching to a centre-off state.

Check the panel opening carefully. This switch has a 12mm mounting diameter and a 6mm mount length, so the dashboard, switch panel or enclosure needs to suit those dimensions. If the cut-out is too small or the mounting depth is unsuitable, the switch will not install correctly even if the wiring is compatible.

The current rating matters just as much as the physical size. Narva lists this switch at 20A @ 12V and 10A @ 24V, so the circuit load and system voltage should be checked before use. If the application draws more than the stated rating, a different switch or a properly designed control arrangement may be needed.

The screw terminals are straightforward for wiring, but they still need the correct wire size, secure terminations and suitable circuit protection. Because the switch is non-illuminated and has no lamp function, it is best suited to applications where no backlighting is required.

For replacement work, compare the part number 60057BL and the product description before purchase. The same general switch style can vary in terminal count, mounting size, contact rating and action, so the exact specification should be matched rather than relying on appearance alone.

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 60057BL 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) 20, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Weight 0.03kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 60057BL, Brand NARVA, Description Narva Metal Changeover Toggle Switch On/On SPDT (Contacts Rated 20A @ 12V), Number of Terminals 2, Switch Action On - On - SPDT, Lamp Colour/s Not Applicable, Mount Length 6mm, Number of Positions 2, Switch Illumination Non Illuminated.

Narva Metal Changeover Toggle Switch On/On SPDT (Contacts Rated 20A @ 12V). Part number 60057BL 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 60057BL, 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.

Compatibility note: Confirm compatibility by matching part number 60057BL, the On - On SPDT action, the 12mm mounting opening, and the 20A @ 12V / 10A @ 24V rating against your application before ordering.

FAQ

What type of switch is this?

It is a Narva metal changeover toggle switch with SPDT action and an On - On position arrangement. It has 2 positions, 1 pole and 2 terminals.

What are the electrical ratings?

Narva lists this switch at 20A at 12V and 10A at 24V. The circuit load should be kept within those ratings for the intended system voltage.

What mounting size does it need?

The mounting opening is 12mm diameter, and the mount length is 6mm. The panel or enclosure needs to suit those dimensions for a proper fit.

Is the switch illuminated?

No. The switch is listed as non illuminated, and lamp colour is marked as not applicable.

What terminals does it use?

It has 2 terminals and screw terminals are listed as a feature. That makes it suitable for a secure wired connection where the application is set up for this terminal style.

What part number should I match for replacement use?

The listed part number is 60057BL. Matching the part number, switch action and mounting dimensions is the safest way to confirm replacement suitability.
