Frequently Asked Questions

Why are master battery disconnect switches necessary?

Master disconnect switches are crucial for safety, especially in performance and racing vehicles. They allow for immediate power cut-off in emergencies, prevent electrical fires, and serve as a theft deterrent. They also prevent battery drain during long periods of storage or maintenance.

What is the difference between SPST and SPDT switches?

SPST (Single Pole, Single Throw) switches have two terminals and are simple ON/OFF switches. SPDT (Single Pole, Double Throw) switches have three terminals and can connect a single input to one of two outputs, making them useful for functions that require switching between two different circuits or modes.

Can I use a standard automotive switch for high-amperage accessories?

No. High-amperage accessories (like large light bars or winches) should always be controlled by a switch that activates a heavy-duty relay. The relay handles the high current load, while the switch only handles the low-current signal required to trigger the relay, preventing the switch from burning out.
