Frequently Asked Questions

Why does my small business need a master battery disconnect switch?

Master battery disconnect switches are essential for safety, especially in commercial or fleet vehicles. They prevent electrical fires during accidents, deter theft, and eliminate parasitic battery drain during long periods of storage or non-use, extending battery life and ensuring the vehicle is ready when needed.

What is the difference between a 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-current signal (from a switch) to control a much higher-current circuit. For high-power accessories (like large fog lights or air horns), you should always use a relay controlled by a smaller, safer dash switch.

Are waterproof switches necessary for trucks and RVs?

Yes, even if the switch is mounted inside the cabin, moisture from spills, high humidity, or external washing can cause corrosion and failure. For any exterior or semi-exposed application (like marine or off-road trucks), waterproof switches are critical for long-term reliability.

Final Thoughts

Equipping your small business fleet with high-quality automotive performance switches and relays is a direct investment in reliability and operational safety.
