Frequently Asked Questions

What is the difference between an automotive switch and a relay?

A switch is a manual device used to open or close a circuit directly. A relay is an electromagnetic switch that uses a small amount of current (from a switch) to control a much larger current flow to a high-power device (like a horn or large light bar). For high-amperage accessories, you should use a switch to trigger a relay.

Are these budget switches durable for outdoor use?

Many budget switches, especially those labeled for marine or off-road use (like those with rubber boot caps or waterproof shells), are designed to resist dust and moisture. Always check the product description for specific IP (Ingress Protection) ratings if you plan to use them in exposed areas.

Can I use a 12V switch on a 24V system?

Only if the switch is explicitly rated for 24V, as several Nilight products listed are (e.g., 20A/12V, 10A/24V). Using a switch rated only for 12V on a 24V system will likely cause premature failure and could pose a safety risk.

Final Thoughts

Finding reliable, budget-friendly automotive switches and relays is easier than ever. The products highlighted above offer excellent value, ensuring your custom wiring projects or simple replacements are both functional and safe. Before purchasing, always confirm the voltage and amperage ratings meet your specific needs. Ready to start your next upgrade?
