OEX Contact Block Normally Open To Suit E-stop Switch ACX3438NO 12/24V 3A

The OEX Contact Block Normally Open to suit an E-Stop switch is a 12 or 24V switch component rated at 3A, supplied as part no. ACX3438NO. It is a non-illuminated unit with 2 terminals and 1 pole, intended for use where a normally open contact arrangement is required.

This contact block is listed to suit part no. ACX3438, which is the key compatibility point to check before ordering. The switch action is Off - Mom On, and the unit is supplied individually as each, with a stated weight of 0.1kg.

For buyers matching an emergency stop switch assembly, the contact type, voltage rating and terminal count are the main details to verify. The OEX description identifies it as a switch component for emergency stop applications, rather than a complete switch assembly.

The one year warranty provides a basic level of product support, but correct selection still depends on confirming the part number ACX3438 and the required normally open contact arrangement before installation.

Application and Buying Notes

Before buying, check that the existing application calls for part no. ACX3438, because this contact block is specifically listed to suit that part number. The most important match points are the normally open contact arrangement, the 2-terminal layout, and the 12 or 24V, 3A electrical rating.

If you are replacing a worn or damaged emergency stop switch contact block, compare the switch action and physical connection details carefully. This unit is described as Off - Mom On, with 1 pole and 2 positions, so it should only be selected where those details align with the original component.

The non-illuminated design is also worth confirming if the original assembly uses no lamp. The lamp colour is listed as not applicable, which reinforces that this is a contact block rather than an illuminated switch module.

For electrical accessories such as this, small differences in terminal count, contact type or voltage rating can change suitability. Confirm the application against the original part marking ACX3438 and the existing switch setup before ordering, especially where the equipment operates on either 12V or 24V systems.

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 ACX3438NO 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 Open To Suit E-Stop Switch. Part number ACX3438NO 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 ACX3438NO, 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 matching the original part number ACX3438 and checking that the application requires a normally open, non-illuminated emergency stop switch contact block rated at 12 or 24V and 3A.
