For a basic SPST switch, you will usually find two terminals, often marked "30" and "87". A successful installation requires careful planning, the right tools, and strict adherence to safety protocols to prevent short circuits or component failure.
How to Wire Rocker Switch Terminal: Understanding Terminal Codes and Connections
Switches are typically labeled with terminal codes that define their electrical behavior. Terminal Code General Meaning Function 30 Power Input Connected to the positive battery source or a fused power line.
87 Output Connected to the device; receives power when the switch is activated. Wiring a rocker switch correctly is a fundamental skill for anyone working on automotive electrical systems, marine applications, or custom electronics projects.

In more complex SPDT switches, a third terminal labeled "87a" or "87b" becomes available, allowing the circuit to switch between two different outputs. Using the correct gauge wire is equally important; a switch rated for 10 amps cannot handle the load of a high-drain accessory without overheating.
