OEX Rocker Switch Momentary On/off Momentary On Dpdt 20A 12V ACX3783BL

The OEX Rocker Switch is a 3-position momentary on/off/momentary on switch with DPDT action and 6 blade terminals. It is rated at 20 amps at 12V, with the feature listing also stating suitability for 12 or 24V use, so the voltage and circuit requirements should be checked carefully before purchase.

This switch is part number ACX3783BL and is sold as a single unit. It is a non-illuminated rocker switch with 2 poles and 6 terminals, making it a straightforward electrical control component where the correct switching pattern and terminal layout matter more than appearance.

Mounting size is listed as 21 x 37mm, with a mount length of 3mm and a very light unit weight of 0.02kg. Those dimensions are important if you are replacing an existing dash, console, or panel switch and need the new unit to fit the opening and mounting arrangement already in place.

Application and Buying Notes

Before ordering, confirm the switch pattern you need. This unit is a momentary on/off/momentary on DPDT rocker with 3 positions and 6 blade terminals, so it is not interchangeable with a standard latching on/off switch unless the wiring and function match exactly. The part number ACX3783BL is the best reference point when comparing against a removed switch or an existing catalogue listing.

Check the panel opening carefully against the stated mounting hole size of 21 x 37mm. The listed mount length is 3mm, so clearance behind the panel should also be considered if the installation space is tight. A switch can have the correct electrical rating and still not suit the physical opening, terminal access, or depth available behind the mounting surface.

Electrical rating matters just as much as the shape. The switch is rated at 20A at 12V, and the feature listing also notes 12 or 24V. If the circuit load, wiring size, or system voltage does not align with those details, the switch should not be treated as a universal replacement. Matching the original wiring arrangement and verifying the terminal count are the safest ways to avoid installation problems.

Because this is a non-illuminated rocker with no lamp colour specified, it is best suited to installations where backlighting is not required. If your original switch has an illuminated face, warning light, or symbol lighting function, compare that carefully before buying so the replacement matches the vehicle or accessory layout.

The one-year warranty applies to the product as supplied, but correct selection still depends on confirming the application, mounting size, terminal layout, and rated load. For parts like this, the most reliable approach is to compare the old switch, the part number ACX3783BL, and the 21 x 37mm mounting opening before fitting.

If you are replacing a switch in an accessory circuit, take note of the 6 blade terminals and DPDT configuration before disconnecting the old unit. A clear terminal count check helps avoid rewiring errors, especially where the switch is used for directional or function-changing control rather than a simple on/off job.

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 ACX3783BL 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.

OEX Rocker Switch Momentary On/Off Momentary On DPDT (Contacts Rated 20A @ 12V). Part number ACX3783BL 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 ACX3783BL, 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.

Compatibility note: Confirm fitment by matching part number ACX3783BL, the 21 x 37mm mounting hole size, the 6 blade terminals, and the Mom On - Off - Mom On - DPDT switching pattern against the original switch and wiring layout before purchase.
