Battery switches are used to control the flow of electricity to different parts of a boat, such as lights, pumps, and electronics. The Perko battery switch is a popular choice for boaters because it is easy to install and use. In this article, we will provide a wiring diagram for the Perko battery switch and answer some frequently asked questions about its operation.

| Red | Positive Battery Cable | BOTH or 1 |
| Yellow | Accessory Power | BOTH or 2 |
| Black | Negative Battery Cable | All Positions |
To wire the switch, follow these steps:
Step 1: Disconnect the Battery
Before beginning any electrical work, always disconnect the battery by removing the negative cable.
Step 2: Mount the Switch
Choose a location for the switch that is easily accessible and close to the battery. Mount the switch using the included template and screws.
Step 3: Connect the Cables
Connect the red positive battery cable to the “C” terminal on the switch and run a new cable to the starter motor. Connect the yellow accessory power cable to the “1” or “2” terminal on the switch and run a new cable to the fuse panel. Connect the black negative battery cable to the “B” terminal on the switch and run a new cable to the engine block.
Step 4: Test the System
Reconnect the battery and test the system by turning the switch to the different positions. Make sure all accessories and electronics are functioning properly.
