The OEX ACX3678 is a 12V, 10A illuminated On/Off push button switch in a SPST (Single Pole Single Throw) configuration, featuring a dual-colour green/red LED indicator. Unlike the momentary ACX3677BL which returns to Off when released, the ACX3678 is a latching push button pressing it toggles the switch between On and Off states, remaining in the selected position until pressed again.
The dual-colour LED provides unambiguous status indication at a glance: green when the switch is On (circuit active) and red when the switch is Off (circuit inactive). This immediate visual feedback makes it particularly well suited to multi-switch control panels, auxiliary accessory circuits, and installations where confirming the active state of a circuit without inspecting the load itself is important. At 10A and 12V, it is suited to direct switching of most standard 12V accessories, LED lighting circuits, fans, and relay trigger inputs.

Is this a momentary or latching switch?
The ACX3678 is a latching (maintained) switch — pressing it toggles the circuit between On and Off, and the switch stays in the selected position until pressed again. This is different from a momentary switch such as the ACX3677BL, which only activates while the button is held down and returns to Off when released. For circuits that need to stay on without holding the button, use a latching switch like the ACX3678.
What do the green and red LEDs indicate?
Green illuminates when the switch is in the On position (circuit active). Red illuminates when the switch is in the Off position (circuit inactive). This dual-colour indication means the switch always shows its current state — not just when it is active — making it easy to confirm at a glance whether the circuit is on or off in a multi-switch panel.
How does this differ from the ACX1962BL?
The ACX1962BL is a pre-wired mouse-style surface mount switch with adhesive backing, designed for easy surface installation without a panel cutout. The ACX3678 is a panel-mount push button intended for installation in a switch panel or console cutout. Both feature green/red dual-colour LED indication at 10A, 12V, but are suited to different installation styles.
What is the maximum load this switch can handle directly?
This switch is rated at 10A at 12V. For loads exceeding 10A, use the switch to trigger a relay rather than wiring the load directly through the switch contacts.
What mounting hole does this switch require?
Mount diameter is not specified in the supplier data for this SKU. Confirm the required panel cutout size with OEX before installing.
