Narva Push Button Switch Momentary On Spst 16A 12V 60040BL

The Narva Push Button Switch Momentary On SPST is a panel-mount switch with a 12mm mounting opening, 2 terminals, and a momentary action set up as Off - Mom On - SPST. It is rated at 16A at 12V, with an 8A rating at 24V, making it suitable where a compact, non-illuminated push switch is required for 12V automotive or accessory control circuits.

This switch is supplied as part number 60040BL and is listed as a Narva switch with a 1-year warranty. The unit weighs 0.015kg and uses a 4mm mount length, which are useful checks when you are confirming panel depth, fitment space, and wiring access before ordering.

Because it is a push-button, momentary-on style switch with SPST contacts and 2 terminals, it is intended for simple on-demand control rather than a maintained latching function. That makes the switch action and electrical rating the main points to verify against the circuit you are working on, especially where the load sits near the 16A at 12V limit.

Application and Buying Notes

When checking whether this switch is suitable, start with the part number 60040BL, the 12mm mounting opening, and the momentary Off - Mom On - SPST action. Those three details matter most because they confirm the physical panel fit, the switch behaviour, and the contact arrangement needed by the circuit.

The 16A rating at 12V is the key electrical figure for 12V use, while the 8A rating at 24V matters if the switch is being considered for a higher-voltage system. Keep the load within the stated rating and avoid assuming it is suitable for any circuit just because the panel hole size matches.

This is a non-illuminated switch with 2 terminals and 1 pole, so it suits simple switching applications rather than multi-circuit or backlit installations. If you need an illuminated switch, a latching function, or more than one switched circuit, this model is not the right match based on the listed specifications.

The listed mount length is 4mm and the unit weight is 0.015kg, which are small but useful details when checking a dash panel, console, or control box for available depth and cable clearance. It is worth confirming the panel material and thickness before fitting, so the switch can seat correctly in the 12mm opening.

If you are replacing an existing switch, compare the switch action, terminal count, and mounting diameter against the original unit rather than relying on appearance alone. A push-button switch can look similar to other panel switches, but the internal contact type and action are what determine whether it will operate as intended in your application.

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 60040BL 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) 16, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Push, Weight 0.015kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 60040BL, Brand NARVA, Description Narva Push Button Switch Momentary On SPST (contacts Rated 16A @ 12V), Number of Terminals 2, Switch Action Off - Mom On - SPST, Lamp Colour/s Not Applicable, Mount Length 4mm, Number of Positions 2, Switch Illumination Non Illuminated.

Narva Push Button Switch Momentary On SPST (contacts Rated 16A @ 12V). Part number 60040BL should be checked first. Listed voltage is 12. Listed output rating is 16. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 60040BL, 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 16 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 the part number 60040BL, the 12mm mounting diameter, the 2-terminal SPST layout, and the momentary Off - Mom On action to your existing switch or application before ordering.
