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