Frequently Asked Questions

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 small amount of current (from a switch) to control a much larger current in a separate circuit. Relays are essential for protecting low-amperage switches from high-amperage accessories like horns or large light bars.

What does the amperage rating on a switch mean?

The amperage rating (e.g., 20A/12V) indicates the maximum continuous current the switch can safely handle without overheating or failing. Always ensure the switch rating exceeds the maximum current draw of the device it is controlling.

Are the Nilight rocker switches truly waterproof?

Many Nilight rocker switches and switch panels are rated IP65 or IP68, meaning they are highly resistant to dust and water ingress. This makes them ideal for use in exposed environments like boat dashboards, UTVs, and exterior vehicle mounting.

Why would a small business need a battery disconnect switch?

Battery disconnect switches (like the Top Post Disconnect) are crucial for vehicles in long-term storage (RVs, boats) to prevent parasitic battery drain. They are also a vital safety measure for technicians performing electrical repairs, allowing for quick and complete power cut-off.
