OEX Rocker Switch On/off Spst 25A 12V Part No. ACX3779BL

The OEX Rocker Switch On/Off SPST is a 12V switch with contacts rated at 25A and a 1 pole, 2 position layout. It uses 2 blade terminals and is supplied as a non-illuminated rocker switch, making it a straightforward option where a simple on/off control is required.

This switch is identified as Part No. ACX3779BL and is sold as each. The mounting requirement listed is a 21 x 37mm mounting hole, with a mount length noted as 3mm. Those dimensions matter when checking whether the switch will physically suit the panel or enclosure you plan to use.

For buyers comparing replacement electrical accessories, the most important details here are the 12V rating, 25A power rating, SPST action and 2-terminal arrangement. Those specifications define the switch’s intended use and help narrow it to applications that match the electrical load and mounting style.

OEX lists this item in the auto electrical accessories group, and the unit weighs 0.03kg. The switch is a conventional rocker type with no illumination, so it suits installations where a simple, non-lit control is preferred over a backlit or indicator style switch.

Application and Buying Notes

Before ordering, check the panel opening carefully against the listed 21 x 37mm mounting hole and note the 3mm mount length. These dimensions are the most useful physical checks if you are replacing an existing rocker switch or cutting a new opening.

Confirm the electrical requirements match the 12V supply and the 25A rating. A switch with SPST on/off action and 2 blade terminals is intended for simple single-circuit control, so it is important to compare the terminal count and switching style with the original part.

Because this switch is non-illuminated, it will not provide a lighted indicator in the rocker itself. If your original switch includes illumination, warning symbols, or a different lens style, that should be checked before purchase so the replacement matches the original function and appearance.

The part number ACX3779BL is the clearest reference for cross-checking. When replacing an electrical control component, it is best to verify the part number, terminal layout, mounting size and operating style together rather than relying on appearance alone.

The one year warranty applies to the product as supplied. As with any electrical switch, correct installation and a suitable circuit load are important, particularly where the switch is being used near its 25A limit.

If you are fitting this into a custom setup, compare the switch dimensions, terminal style and on/off function with the equipment instructions or the removed component. That helps avoid ordering a switch that looks similar but differs in rating or physical fit.

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 ACX3779BL 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) 25, Voltage 12, Mount Length 3mm, Number of Positions 2, Item Type Switch, Weight .03kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. ACX3779BL, Brand OEX, Description OEX Rocker Switch On/Off SPST (Contacts Rated 25A @ 12V), Number of Terminals 2, Switch Action On - Off - SPST, Lamp Colour/s Not Applicable, Number of Poles 1, Switch Type Rocker, Switch Illumination Non Illuminated.

OEX Rocker Switch On/Off SPST (Contacts Rated 25A @ 12V). Part number ACX3779BL 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 ACX3779BL, 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.

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 matching Part No. ACX3779BL, the 12V and 25A ratings, the 2 blade terminals, and the 21 x 37mm mounting hole before purchase.
