OEX Rocker Switch On/off Spst 12V Green Illuminated 10A Part No. ACX3790

The OEX Rocker Switch, part number ACX3790, is a 12V on/off SPST switch with a green illuminated lamp and contacts rated at 10A @ 12V. It is a compact electrical control component suited to 12V vehicle and accessory installations where a simple single-pole, two-position switch is required.

This switch uses a rocker style action with 1 pole, 2 positions, and 4 terminals, with the supplied feature listing also noting 3 blade terminals. The mounting requirement is a 20mm round mounting hole, which is the main physical check to confirm before fitting it to a panel or dash location.

For buyers comparing replacement switches, the useful identifiers here are the OEX brand, ACX3790 part number, 12V operating voltage, 10A power rating, and illuminated green lamp colour. It is sold individually as each, and the listed weight is 0.04kg.

A specific note applies where 24V systems are involved: for 24V applications, use Part No. ACX3912 resistor with the switch. That makes the voltage application an important check before purchase, rather than assuming it will suit both 12V and 24V setups.

Application and Buying Notes

Before ordering, confirm that your panel has a 20mm round mounting hole, as that is the stated mounting diameter for this rocker switch. If the aperture is smaller or larger, the switch will not be a direct fit without modification, and that is the first measurement worth checking.

The electrical rating is 12V and 10A, so the switch should be matched to an application that stays within those limits. The switch action is On - Off - SPST, which means it is intended for simple single-circuit control rather than more complex switching arrangements.

Terminal count matters as well. This switch is listed with 4 terminals, while the feature list also notes 3 blade terminals, so it is sensible to compare the terminal layout on your existing switch before replacing it. Matching the physical terminal arrangement helps avoid wiring mismatch at installation.

If you are working on a 24V application, the supplied note specifies the use of Part No. ACX3912 resistor with the switch. That is a specific compatibility point, and it should be confirmed before purchase rather than assumed after the fact.

The green illumination is a useful visual cue in dark cabins or accessory panels, but it does not change the fundamental electrical requirement: the switch still needs to suit a 12V, 10A application. Check the circuit load, the panel depth allowance, and the terminal layout together before fitting.

For replacement work, the best approach is to compare the part number ACX3790, the 20mm mounting hole, the 12V rating, and the SPST on/off action against the switch being removed. Those details are the practical checks that matter most when choosing a direct replacement.

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 ACX3790 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) 10, Voltage 12, Mount Diameter 20mm, Note NOTE: For 24V applications, use Part No. ACX3912 resistor with the switch, Number of Positions 2, Item Type Switch, Weight .04kg.

Additional published details for cross-checking include Product Group 1 AUTO ELEC ACCESSORIES, Part No. ACX3790, Brand OEX, Description OEX Rocker Switch On/Off SPST 12V Green Illuminated (Contacts Rated 10A @ 12V), Number of Terminals 4, Switch Action On - Off - SPST, Lamp Colour/s Green, Mount Length 2mm, Number of Poles 1, Switch Type Rocker.

OEX Rocker Switch On/Off SPST 12V Green Illuminated (Contacts Rated 10A @ 12V). Part number ACX3790 should be checked first. Listed voltage is 12. Listed output rating is 10. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3790, 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 10 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching part number ACX3790, 12V operating voltage, 10A rating, SPST on/off action, and the 20mm round mounting hole before purchase. For 24V applications, the specified ACX3912 resistor is required with the switch.

FAQ

What type of switch is the OEX ACX3790?

It is an OEX rocker switch with On - Off - SPST action. The listing also identifies it as 1 pole and 2 positions.

What voltage and current rating does it have?

The switch is rated for 12V and has a 10A power rating. It should be matched to an application that stays within those stated limits.

What size mounting hole is required?

The stated mount diameter is 20mm, with a 20mm round mounting hole listed in the features. That is the key physical fitment check.

Is the switch illuminated?

Yes. The switch illumination is listed as illuminated, and the lamp colour is green.

Can it be used on 24V systems?

The note states that for 24V applications, Part No. ACX3912 resistor is to be used with the switch. That specific requirement should be confirmed before fitting.

What warranty is listed?

The listed warranty is one year.
