Switches—whether they're toggles or rockers, push-button or disconnect—are found in every 12-volt electrical system, doing everything from turning on lights to moderating critical systems. To understand the basics of electrical switches, you must first understand the circuitry inside, then be able to discern the differences between different types of switches. Here's a crash course.

Battery Disconnect switches have several important jobs in commecrial vehicles and equipment. They cut-off electrical power, help protect against electrical fires and theft when equipment is not in use, provide a reliable shutdown of power during maintenance, and protect batteries from excessive drain. Waytek carries a new line of Terra Power Products Battery Disconnect Switches to perform these jobs and help increase the life of your batteries.

Fire trucks, work trucks, towing vehicles, boats, ambulances and off-road equipment do more than start their engines and move from point A to point B. Accessory components such as lights, entertainment systems, communications equipment and more are electrical loads drawing power from the battery when the engine is off. A common solution is adding an auxiliary battery to operate the additional loads, however if an auxiliary battery is simply wired into the vehicle electrical system, you will experience multi-battery drain issues. Starter batteries need to be isolated from auxiliary batteries.
