Application and Buying Notes

This contact block is intended to suit OEX part no. ACX3438, so the most reliable buying check is to match the part number on the existing component or the related E-Stop switch assembly. Because it is a normally closed contact block, the contact state is a critical detail and should be confirmed before replacement.

The electrical rating is 3 amp at 12 or 24 volt, which means it should only be used where the application falls within that specification. When replacing any switch component, compare the number of terminals, the 1 pole arrangement, and the 2-position setup so the physical and electrical layout aligns with the original item.

This item is non illuminated and uses 2 terminals, so it suits applications that do not require an indicator lamp or additional terminal count. If the existing switch block has different illumination requirements, a different contact block may be needed even if the mounting arrangement looks similar.

The supplied weight is 0.1kg and the unit is sold individually. That makes it straightforward for replacement work, but the important point is still the same: confirm the part number ACX3438NC and the related ACX3438 application rather than relying on appearance alone.

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 ACX3438NC 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 Contact Block Normally Closed To Suit E-Stop Switch. Part number ACX3438NC should be checked first. Listed voltage is 12 or 24. Listed output rating is 3. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3438NC, 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 3 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 checking the part number ACX3438NC and the matching ACX3438 E-Stop application details before purchase. If the original switch differs in contact form, terminal count, illumination, or voltage rating, do not assume it is the same part.
