OEX Toggle Switch On/off Spst 20A 12V 12MM Mount ACX3913BL

The OEX ACX3913BL is a toggle switch with On-Off SPST action, rated at 20A on 12V systems. It is a 2-position, single pole single throw switch with 2 blade terminals, supplied as a single unit for vehicle electrical applications.

Mounting dimensions are important with this part: the listed mount diameter is 12mm, with a mounting stem of 12.50mm and a mount length of 3mm. Those measurements need to suit the panel or housing before fitting, especially where a close tolerance switch opening is involved.

The switch is non illuminated and uses 2 terminals, with lamp colour noted as not applicable. It also includes a pre-mounted spring loaded switch cover, and the switch is matched with the cover for smooth operation. The cover options listed are ACX3915BL with White Missile Cover and ACX3916BL with Yellow Missile Cover.

Application and Buying Notes

Confirm the panel opening before ordering. The critical dimensions here are the 12mm mount diameter, the 12.50mm mounting stem and the 3mm mount length. If the opening or retaining arrangement does not suit those measurements, the switch may not sit correctly or operate as intended.

Electrical load is another key check. This switch is rated at 20A on 12V systems, so it should be selected for circuits that stay within that rating. As with any vehicle electrical switch, the current draw of the circuit and the quality of the wiring, terminals and protection devices need to be suitable for the application.

The switch is a single pole single throw unit with 2 blade terminals and 2 positions, which makes it a straightforward On-Off switch rather than a multi-function control. If you are replacing an existing switch, compare the part number ACX3913BL, the terminal style, and the physical layout of the mounting stem and cover before purchase.

The included spring loaded switch cover is part of the package and is matched to the switch for smooth operation. If you are working around an existing dash, console or custom panel, check whether the cover style and clearance will suit the installation. The product is non illuminated, so it will not provide switch backlighting or an indicator lamp function.

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 ACX3913BL 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, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Switch Illumination Non Illuminated.

OEX Toggle Switch On/Off SPST (Contacts Rated 20A @ 12V). Part number ACX3913BL should be checked first. Listed voltage is 12. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3913BL, 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 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.

Compatibility note: Always confirm fitment using the part number ACX3913BL, the 12mm mounting diameter, the 12.50mm mounting stem, the 3mm mount length, and the 20A 12V On-Off SPST specification before ordering.
