Frequently Asked Questions

What is the primary purpose of a battery disconnect switch?

A battery disconnect switch is primarily used to completely isolate the battery from the vehicle's electrical system. This serves three main purposes: safety (emergency power cut-off), maintenance (preventing battery drain during storage), and security (acting as an anti-theft kill switch).

Do I need a relay for my automotive switch?

If the accessory you are controlling (e.g., headlights, air horn, high-power LED light bar) draws more current than the switch is rated for, you absolutely need a relay. The switch activates the low-current relay coil, which in turn closes the high-current circuit to the accessory, protecting the switch and wiring from overheating.

What does 'SPST' mean on a rocker switch?

SPST stands for Single Pole, Single Throw. This is the simplest type of switch, meaning it controls one circuit (Single Pole) and has only two positions: ON or OFF (Single Throw).

Final Thoughts

Investing in high-quality performance switches and relays is crucial for the safety, reliability, and functionality of any customized vehicle. Whether you prioritize emergency power cut-off with a robust disconnect switch or streamlined control with a modern switch panel, the products listed above represent the best options available.
