OEX Toggle Switch On/off/on Dpdt 20A 12/24V IP68 Part No. ACX7638

The OEX Toggle Switch On/Off/On DPDT, part number ACX7638, is a non-illuminated switch rated at 20A and suitable for 12V or 24V systems. It uses a 12mm diameter mounting hole and is fitted with 6 screw terminals, which gives you a straightforward, hard-wired installation where a compact toggle switch is required.

This switch is a 3-position On-Off-On DPDT unit with 2 poles and 6 terminals. That combination is commonly used where a circuit needs positive centre-off control and separate switching paths, so the exact terminal layout and application should be checked before installation.

With an IP68 rating, this OEX switch is intended for demanding environments where protection against dust and water ingress matters. It is supplied as an each item and carries a one year warranty, making it a practical option when you need a sealed toggle switch with clear electrical and mounting details.

For buyers matching an existing switch, the key identifiers here are OEX, ACX7638, 20A, 12 or 24V, On-Off-On DPDT, and the 12mm mounting diameter. Those details matter more than appearance alone when confirming a replacement or selecting a new control switch for an automotive electrical setup.

Application and Buying Notes

Before buying, confirm that your application is designed for a 3-position On-Off-On DPDT toggle switch with 6 screw terminals and a 12mm mounting hole. Those are the main physical and electrical checkpoints for ACX7638, and they need to line up with the panel opening, wiring layout and circuit function you already have in place.

The 20A rating and 12V or 24V specification are important because the switch must suit both the system voltage and the load it will control. If your existing switch is marked with a different current rating, pole count, or terminal count, compare it carefully rather than relying on the switch shape alone.

IP68 protection is a useful feature for exposed or hard-working locations, but it does not remove the need to check the rest of the installation. Make sure the mounting arrangement, wiring access, and seal condition are appropriate for the vehicle or equipment where the switch will be fitted.

Because this is a non-illuminated toggle switch, it is best suited to applications where no lamp function is needed. If your current switch uses an indicator light or a specific lamp colour, this unit is not listed with illumination and should only be chosen where that detail is not required.

When matching a replacement, the most reliable checks are the part number ACX7638, the OEX brand, the On-Off-On DPDT switch action, and the 12mm mounting diameter. If any of those differ from your original component, take time to verify the wiring and function before installation.

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 ACX7638 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 or 24, Mount Diameter 12mm, Number of Positions 3, Item Type Switch, Weight .08kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. ACX7638, Brand OEX, Description OEX Toggle Switch On/Off/On DPDT (Contacts Rated 20A) IP68, Number of Terminals 6, Switch Action On - Off - On - DPDT, Lamp Colour/s Not Applicable, Number of Poles 2, Switch Type Toggle, Switch Illumination Non Illuminated.

OEX Toggle Switch On/Off/On DPDT (Contacts Rated 20A) IP68. Part number ACX7638 should be checked first. Listed voltage is 12 or 24. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX7638, 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 or 24 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.

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 number ACX7638, the OEX brand, the 12mm mounting hole, the 6-terminal On-Off-On DPDT layout, and the 20A 12/24V rating against your existing switch and application requirements before ordering.
