A rocker switch looks simple from the outside. You press one side down, the other side rises, and the circuit turns on or off.<\/p>\n\n\n\n

But once you look at the back of the switch, things can get confusing.<\/p>\n\n\n\n

Some rocker switches have two pins. Others have three, five, six, or even seven. Some are marked with PWR, ACC, and GND, while others only use numbers. If the switch has an LED, you also need to know whether the light is powered by the load, by a separate backlight circuit, or by the vehicle\u2019s dash light system.<\/p>\n\n\n\n

That is where many DIY wiring jobs go wrong.<\/p>\n\n\n\n

A rocker switch is one of the most common electrical switches used in vehicles, boats, appliances, control panels, power strips, and industrial equipment. It is popular because it is easy to operate, gives clear ON\/OFF feedback, and can be used in many low-voltage and high-voltage applications.<\/p>\n\n\n\n

In this guide, we\u2019ll explain what a rocker switch is, how it works, the different types available, how to wire a rocker switch safely, and how to troubleshoot common problems.<\/p>\n\n\n\n

We\u2019ll also cover lighted rocker switches, pin configurations, relay wiring, IP ratings, and the key things to check before buying one.<\/p>\n\n\n\n
