Voltage Drop Resistor - 24V to 12V for LED Illuminated Switches (ACX3912)

The OEX ACX3912 Voltage Drop Resistor is a compact, reliable solution for running 12V illuminated switches on vehicles or equipment fitted with a 24V electrical system. Designed specifically for switches with built-in LED indicators, this resistor safely reduces 24V down to a switch-friendly level, preventing LED burnout, flickering or premature failure.

Lightweight and easy to install, the ACX3912 is ideal for trucks, heavy machinery, marine environments, caravans, RVs and custom electrical builds. If you're retrofitting dash panels, upgrading control switches or converting accessories to suit a 24V platform, this resistor ensures stable illumination without the need for a full voltage reducer or complex wiring modifications.

Built to OEX’s dependable standards, the ACX3912 provides a simple, effective way to integrate modern 12V LED rocker switches into any 24V system.
