Frequently Asked Questions

What is the difference between a switch and a relay in a car?

A switch is a manual device used to open or close a low-current circuit. A relay is an electromagnetic switch that uses a low-current signal (from a switch or ECU) to control a separate, high-current circuit. Relays are essential for protecting sensitive switches and wiring from high-amperage loads like headlights or large light bars.

What does 'SPST' mean on a rocker switch?

SPST stands for Single Pole, Single Throw. This is the simplest switch type, meaning it has one input and one output, used only to turn a circuit completely on or off. Most basic automotive accessory switches are SPST.

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

Only if the switch is explicitly rated for 24V operation, as many of the products listed here are (e.g., Nilight 20A/12V, 10A/24V). Using a switch only rated for 12V in a 24V system will likely cause the switch to fail prematurely or create a fire hazard due to excessive voltage and heat.

Final Thoughts

Upgrading or repairing your vehicle’s electrical system requires components that are reliable and correctly rated for the job.
