OEX Micro Switch On-off / Off-on 15A 12 Or 24V ACX7640

The OEX Micro Switch On-Off / Off-On is a compact 1 pole switch with 3 terminals, rated for up to 15A on 12V or 24V systems. It carries part number ACX7640 and is supplied as a single unit, making it a straightforward choice when you need a simple micro switch with a defined switching action.

This switch is non-illuminated and has a mount length of 25mm, so space and panel layout should be checked before purchase. The listed switch action is On-Off / Off-On, which is the key identifier to match against the replacement part or the control function required in the vehicle or application.

OEX lists this item in the auto electrical accessories group, under fuses, breakers, relays and switches. Weight is listed at 0.1kg, and the warranty is one year. For buyers replacing an existing switch, the part number ACX7640 and the 3 terminal layout are the most useful identifiers to confirm before ordering.

Application and Buying Notes

Before ordering, compare the existing switch against ACX7640, the 3 terminal arrangement, and the On-Off / Off-On switching action. Those details matter more than the general description alone, because a micro switch can look similar to others while differing in terminal count, position logic, or mounting length.

The electrical rating is listed at 15A on 12V or 24V systems, so the load on the circuit should stay within that rating. If the replacement circuit draws close to the limit, check the current draw of the connected accessory and confirm the switch is appropriate for the intended duty.

The mount length is 25mm, which is a practical sizing detail when replacing a panel-mounted control. Measure the available space and compare it with the existing opening or mounting arrangement, especially if the switch sits in a tight dash, console, or accessory panel location.

As this item is non-illuminated, it will not provide a lamp function or backlighting. If the original switch includes illumination, the appearance and operation will differ even if the switching function is otherwise similar. Confirm the required style before buying, particularly where visual matching is important.

The one-year warranty applies to the item as sold, but the most reliable way to avoid delays is to verify the part number ACX7640, the terminal count, and the voltage rating against the existing component. That is the best check for a direct replacement when only limited application detail is available.

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 ACX7640 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) 15, Voltage 12 or 24, Mount Length 25mm, Number of Positions 2, Item Type Switch, Weight .1kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. ACX7640, Brand OEX, Description OEX Micro Switch On - Off /Off - On (Contacts Rated 15A @ 12 or 24V), Number of Terminals 3, Switch Action On - Off /Off - On, Lamp Colour/s Not Applicable, Number of Poles 1, Switch Type Micro, Switch Illumination Non Illuminated.

OEX Micro Switch On - Off /Off - On (Contacts Rated 15A @ 12 or 24V). Part number ACX7640 should be checked first. Listed voltage is 12 or 24. Listed output rating is 15. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX7640, 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 15 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number ACX7640, the 3 terminal layout, the 25mm mount length, and the On-Off / Off-On switch action with the existing part or application requirements before ordering.
