Frequently Asked Questions

What is the difference between a switch and a relay?

A switch directly controls the flow of electricity to a circuit. A relay is an electrically operated switch that uses a small amount of current (from a low-amperage switch) to control a much larger current flow to a high-power device (like a horn, fan, or large light bar). Relays protect the main switch and wiring from high heat and current.

Why do I need a battery disconnect switch?

Battery disconnect switches are essential for safety, especially in racing or performance vehicles, as they allow for immediate power shut-off in an emergency. They also prevent battery drain during long periods of storage and act as a theft deterrent.

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

No, unless the switch is explicitly rated for 24V (or 12V/24V dual compatibility). Using a 12V-only switch on a 24V system will cause the switch to fail quickly due to excessive voltage and arcing.
