Some DC electromechanical switches are hard to come by in today’s environment of materials shortages and shipping constraints. In contrast, solid-state switches and contactors can be easier to source and offer many advantages over traditional switches—often at the same price point.

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.
