Narva Rocker Switch Off/on Spst 25A 12V 62050BL

The Narva Rocker Switch Off/On SPST is a straightforward 2-position switch rated at 25A at 12V, with a 12.5A rating at 24V. It uses a 24mm mounting opening and has 2 terminals with push-on connections, making it a practical choice where a simple on/off rocker is required and the panel opening matches the specified size.

This switch is identified as part number 62050BL and is supplied as a non-illuminated unit. It is a single-pole, single-throw design, which means it provides a basic on/off function rather than a more complex switching arrangement. The switch action is listed as On - Off - SPST.

For buyers replacing a damaged switch or planning a new install, the key checks are the 24mm mount diameter, the 2-terminal layout, and the 25A at 12V contact rating. Those details matter because the switch must suit both the electrical load and the physical panel opening before it can be used with confidence.

Application and Buying Notes

Before ordering, confirm the panel cut-out is suitable for a 24mm mounting opening and that the switch location can accept a rocker style unit with a 3mm mount length. The physical size is just as important as the electrical rating, because a switch that does not fit the opening properly will not install correctly.

Electrical load should also be checked carefully. This Narva switch is rated at 25A at 12V and 12.5A at 24V, so it should only be used where the circuit demand stays within those limits. If the circuit is near that rating, it is sensible to allow margin rather than running at the upper edge all the time.

The switch has 2 terminals and uses push-on terminals, so the wiring setup needs to match that arrangement. Because it is a non-illuminated SPST rocker, it suits simple on/off control rather than applications that need indicator lighting or multiple switching positions.

For replacements, comparing the existing switch against part number 62050BL is the safest approach. Matching the part number, terminal count, mounting opening, and voltage rating gives the best chance of selecting the correct item without having to rely on guesswork.

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 62050BL 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.

Additional published details for cross-checking include Part No. 62050BL, Brand NARVA, Description Narva Rocker Switch Off/On SPST (Contacts Rated 25A @ 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 Rocker Switch Off/On SPST (Contacts Rated 25A @ 12V). Part number 62050BL should be checked first. Listed voltage is 12. Listed output rating is 25. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 62050BL, 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 25 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: Please confirm compatibility using part number 62050BL, the 24mm mounting opening, the 2-terminal push-on layout, and the 25A at 12V / 12.5A at 24V ratings before purchase.
