A switch is a manual device used to open or close a circuit (like a light switch). A relay is an electromagnetic switch that uses a small current (from a switch) to control a much larger current (to a high-power device like a starter motor or large light bar). Relays protect the main switch from high current damage.
Battery disconnect switches (or kill switches) are crucial for safety in racing to quickly shut down all electrical power in an emergency (like an accident or fire). They also prevent battery drain during long periods of storage and act as a theft deterrent.
Yes. Off-road vehicles (trucks, Jeeps) and marine vessels are exposed to water, mud, and dust. Waterproof switches (rated IP67 or higher) prevent internal corrosion and short circuits, ensuring reliability in harsh conditions.
Selecting the best automotive performance switches and relays ensures not only the functionality of your custom electrical systems but also the overall safety and reliability of your vehicle. From heavy-duty battery cut-offs essential for racing to sophisticated multi-gang switch panels for off-road accessories, the products listed above represent the best in quality and performance. Review your specific needs, check the amperage ratings, and invest in components that will withstand the demands of your application.
