OEX Toggle Switch Mom On - Off - Mom On Dpdt 15A 12V - ACX3919BL

The OEX Toggle Switch Mom On - Off - Mom On is a double pole, double throw switch rated at 15A and 12V, with part number ACX3919BL. It uses a standard toggle lever, 6 blade terminals, and a 12mm mount diameter, making it a compact electrical control component for suitable 12V applications.

This switch is described as a reversing polarity switch with bridged terminals, which is an important detail when comparing it with other toggle switches. The switch action is Mom On - Off - Mom On - DPDT, so the centre position is off and the outer positions are momentary rather than latched.

Construction details include a metal lever and bushing made from nickel plated brass, a phenolic base, and non-illuminated operation. Those details matter when selecting a switch for a panel install, especially where terminal style, mounting size, and contact arrangement need to match the job at hand.

Application and Buying Notes

Before ordering, confirm the control you are replacing is a 12V switch with a 15A contact rating and a 12mm mounting hole. Those are the main physical checkpoints supplied here, and they are the first items to compare against the existing panel opening and wiring arrangement.

The 6 blade terminals and DPDT layout are important if the original switch uses a reversing polarity arrangement or a bridged terminal setup. If your existing switch uses a different terminal count, pole arrangement, or action pattern, this unit may not be interchangeable without changes to the wiring.

Because the switch action is Mom On - Off - Mom On, it is suited to circuits where the lever returns to centre when released. That is different from a maintained on/off switch, so the correct function needs to be matched before purchase.

The nickel plated brass lever and bushing, phenolic base, and non-illuminated design are practical details for panel compatibility, but they do not replace a fitment check. Measure the panel opening, compare the terminal style, and verify the required switching function against the vehicle or equipment you are working on.

If you are matching by part number, ACX3919BL is the key identifier to confirm. Where a replacement is being sourced for a specific application, it is best to verify both the part number and the switch specification together, 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 ACX3919BL 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 Toggle Switch Mom On - Off - Mom On - DPDT (Contacts Rated 15A). Part number ACX3919BL should be checked first. Listed voltage is 12. Listed output rating is 15. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3919BL, 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 15 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number ACX3919BL, 12V rating, 15A contact rating, 12mm mount diameter, 6 blade terminals, and the Mom On - Off - Mom On DPDT switching action before purchase.
