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. A relay is an electromagnetic switch that uses a low-power signal (from a switch or ECU) to control a high-power circuit. Relays are essential for protecting low-amperage switches from high-amperage accessories like horns or large light bars.

Are these affordable switches difficult to install?

Most modern affordable automotive switches, especially rocker and round toggle types, are designed for easy, drop-in installation. Many include pre-wired harnesses or jumper wires (like the Nilight sets) to simplify the connection process. Always disconnect the battery before working on electrical systems.

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

Only if the switch is explicitly rated for 24V operation, usually indicated on the product specifications (e.g., 20A/12V, 10A/24V). Using a 12V-only switch on a 24V system will cause premature failure due to excessive voltage stress.
