Frequently Asked Questions

What is the difference between a switch and a relay in automotive applications?

A switch directly controls the flow of electricity in a circuit, often handling lower currents. A relay is an electromagnetic switch that uses a small amount of current from a switch (or control signal) to control a much larger current in a separate circuit. Relays are essential for protecting sensitive switches and wiring from high-amperage loads like headlights or fuel pumps.

Why do I need a battery disconnect switch?

Battery disconnect switches (or kill switches) serve several purposes: they prevent parasitic battery drain during long-term storage, provide a quick way to cut power in an emergency (like an electrical fire), and are often required for safety in racing applications.

What does SPST mean on a rocker switch?

SPST stands for Single Pole, Single Throw. This is the simplest type of switch, meaning it has one input terminal (the pole) and one output terminal (the throw). It simply turns a circuit either completely ON or completely OFF.

Final Thoughts

Investing in reliable automotive performance switches and relays is a non-negotiable step for any serious vehicle modification. Whether you need the high-amperage safety of a QuickCar disconnect switch, the versatility of an Auxbeam switch panel, or simple, reliable rocker switches from Nilight, the products listed above represent some of the best options available for durability and performance. Review your specific current requirements and environmental needs before making your final selection to ensure a safe and effective electrical system upgrade.
