OEX Toggle Switch On/off Spst 12V Amber Illuminated 20A – ACX3888BL

The OEX Toggle Switch ACX3888BL is a 12V, 20A switch with a single pole, double throw style listed here as On/Off - SPST, using 3 blade terminals and a 12mm mounting hole. It is designed as an illuminated toggle switch with amber lamp colour/s, making it suitable where a clearly visible switched position is needed in a compact 2-position layout.

With a 12V electrical rating and contacts rated 20A @ 12V, this switch suits low-voltage automotive and accessory control applications where the current draw stays within the stated rating. The unit measures as a 12mm mounting hole item and is supplied as one switch per each, under OEX part number ACX3888BL.

The listed construction details are straightforward: 1 pole, 2 positions, 3 blade terminals, On/Off operation, and amber illumination. Those are the key identifiers to check against your existing panel cut-out, wiring, and circuit load before ordering, especially if you are replacing an existing illuminated toggle switch.

Application and Buying Notes

Before buying, match the part number ACX3888BL and check that your panel accepts a 12mm mounting hole. That mounting size is one of the most important practical checks, because a switch can have the right electrical rating but still not suit the dash, switch panel, or bracket opening you already have in place.

The switch is listed as 12V and 20A, so the circuit it is used on should stay within those values. If the accessory or load draws more than the stated 20A rating, the switch is not the right choice. The 3 blade terminals and 1 pole, 2 position On/Off - SPST layout should also be compared with the existing wiring arrangement before installation.

Because this is an illuminated toggle with amber lamp colour/s, it may be chosen where a visible status light is wanted as part of the switch. The illumination style does not replace the need to confirm the circuit function, terminal count, and physical space behind the panel. Allow enough room for the switch body, wiring, and any connector clearance.

If you are replacing an existing switch, compare the old unit against the listed details rather than relying on appearance alone. Confirm voltage, amperage, terminal count, mounting diameter, and action type. Those are the safest checkpoints when selecting a switch for an automotive electrical application, especially where the panel is already cut to size.

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 ACX3888BL 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) 20, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Switch Illumination Illuminated.

OEX Toggle Switch On/Off SPST 12V Amber Illuminated (Contacts Rated 20A @ 12V). Part number ACX3888BL 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 ACX3888BL, 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 20 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: Confirm fitment by matching the part number ACX3888BL, the 12mm mounting diameter, the 12V / 20A rating, and the 3 blade terminal On/Off - SPST layout to your existing application before purchase.
