OEX ACX1971BL Rocker Switch On/Off SPST Red Illumination

Control your 12V accessories with confidence using the OEX ACX1971BL — a 30-amp illuminated rocker switch built for reliable switching in demanding automotive and marine environments.

Product Overview

The OEX ACX1971BL is a single-pole single-throw (SPST) rocker switch designed for 12V DC applications requiring clear visual status indication. With a 30-amp power rating and red LED illumination, this switch handles high-current accessories like driving lights, light bars, spotlights, pumps, and fans. The 12mm mounting hole suits standard switch panel cutouts, making it ideal for custom dash installations, auxiliary switch panels in 4WDs, or marine helm stations. Three-terminal design simplifies wiring, while the illuminated rocker provides at-a-glance status verification day or night. Backed by OEX's one-year warranty and built to withstand Australian heat, dust, and vibration.

Features & Benefits

30-Amp Capacity — Handles high-draw accessories like LED light bars, spotlights, auxiliary fans, and pumps without overheating or voltage drop, eliminating the need for external relays in most applications.

Red LED Illumination — Backlit rocker provides instant visual confirmation of switch state, preventing accidental accessory activation and making night-time operation foolproof in dark cabins or on moonless outback tracks.

12mm Standard Mounting — Fits common switch panel cutouts used across aftermarket automotive panels, marine helm stations, and custom fabrications, allowing quick integration into existing setups.

SPST Simplicity — Single-pole design keeps wiring straightforward with just three terminals, reducing installation time and troubleshooting complexity compared to multi-pole alternatives.

Rugged Rocker Action — Positive-feedback switching mechanism survives thousands of cycles in high-vibration environments like corrugated dirt roads, boat hulls, and work vehicles.

Frequently Asked Questions

What accessories can I run with a 30A switch? Most LED light bars, spotlights, driving lights, auxiliary fans, water pumps, and air compressors. For loads over 25A continuous or inductive loads like winches, use this switch to trigger a relay instead.

Does the red light stay on when the switch is off?  No — the LED illuminates only when the switch is in the ON position, providing clear status indication without draining your battery when accessories are off.

Will this fit my existing switch panel? If your panel has a 12mm hole, yes. Measure your existing cutout or check your panel specs. This is the standard size for most aftermarket automotive and marine rocker switches.

Can I use this in a marine environment? Yes — the switch is suitable for 12V marine applications, but ensure the installation location is protected from direct water spray. Consider using dielectric grease on terminals in high-moisture areas.

Do I need a relay for my 20A light bar? Not necessarily — the 30A rating handles a 20A load comfortably. However, if your light bar is mounted far from the switch or you want to reduce voltage drop, running a relay near the load is still good practice.
