OEX Push Button Switch Off - Mom On - Spst 12V Green Illuminated 50A ACX3674BL

The OEX push button switch, part number ACX3674BL, is a 12V, single pole single throw switch with an Off - Mom On action and green illumination. It is rated at 50A @ 12V and uses a 22mm mounting stem, which makes the mounting size an important check before ordering.

This switch has 3 blade terminals and is described as a push button engine start switch with green illumination. The terminal note provided identifies Terminal 1 as ignition feed, Terminal 2 as start feed to solenoid, and Terminal 3 as earth connection for active illumination of the button.

For buyers working through a replacement or a custom electrical setup, the key details are the 12V operating voltage, 50A contact rating, 22mm mount diameter, and the 3 terminal layout. Those are the main points to confirm against the existing switch, panel opening, and wiring arrangement before purchase.

Application and Buying Notes

Before buying, match the part number ACX3674BL and check that the vehicle or accessory setup is designed for a 12V switch rated at 50A. The mounting stem is 22mm in diameter, so the panel hole size needs to suit that dimension if you want the switch to seat correctly.

The switch action is listed as Off - Mom On - SPST, so it is intended for a momentary start-style function rather than a maintained on/off control. That matters if you are replacing an existing starter button, because the function must match the way the circuit is meant to operate.

Green illumination is part of the product description, along with silver contacts. If the original switch uses a different lamp colour, terminal arrangement, or mounting size, the replacement should be checked carefully rather than assumed to fit on appearance alone.

For 24V applications, the note supplied calls for part number ACX3912 as a resistor. That is an important limitation to keep in mind if the circuit is not a standard 12V application.

The unit is sold each and carries a one year warranty. If you are comparing options, the safest approach is to verify the mounting diameter, terminal count, voltage, and part number together instead of relying on the general appearance of the switch.

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 ACX3674BL 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) 50, Voltage 12, Mount Diameter 22mm, Note Terminal connections: Terminal 1 = Ignition feed, Terminal 2 = Start feed to Solenoid, Terminal 3 = Earth connection for Active illumination of the button, Number of Positions 2, Item Type Switch, Weight .04kg.

Additional published details for cross-checking include Product Group 1 AUTO ELEC ACCESSORIES, Part No. ACX3674BL, Brand OEX, Description OEX Push Button Switch Off - Mom On - SPST 12V Green Illuminated (Contacts Rated 50A @ 12V), Number of Terminals 3, Switch Action Off - Mom On - SPST, Lamp Colour/s Green, Mount Length 12mm, Number of Poles 1, Switch Type Push.

OEX Push Button Switch Off - Mom On - SPST 12V Green Illuminated (Contacts Rated 50A @ 12V). Part number ACX3674BL should be checked first. Listed voltage is 12. Listed output rating is 50. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3674BL, 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 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by matching part number ACX3674BL, the 12V 50A rating, the 22mm mounting stem, and the 3 terminal wiring layout against your existing switch and application details before ordering.
