4-Pin Rocker Switch Wiring Diagram & Connection Guide
A 4-pin rocker switch wiring diagram helps installers understand the relationship between the switch circuit and the internal LED circuit. Depending on the specific switch configuration, the LED can be wired for dependent illumination or independent illumination.
Option 1: LED On When the Device Is Operating
In this configuration, the internal LED illuminates when the rocker switch is in the ON position and the connected device is operating.
- Input: Connect the power source to the appropriate input terminals.
- Output: Connect the switched output terminals to the load.
- LED Logic: The LED operates together with the switched circuit.
Figure 1: Wiring configuration for LED illumination when the device is operating.
Option 2: LED Remains On When Power Is Available
This configuration can be used when the switch needs to remain visible in a dark environment. The LED is powered independently from the switched load according to the applicable terminal configuration.
- Power: Connect the LED circuit to the appropriate power terminals.
- Load: Connect the equipment to the switched output terminals.
- LED Logic: The LED can remain illuminated while the switch is connected to the power source.

Operation Logic Comparison
| Configuration | Switch State | Device | LED |
|---|---|---|---|
| Dependent | OFF | OFF | OFF |
| ON | ON | ON | |
| Independent | OFF | OFF | ON |
| ON | ON | ON |
Wiring & Safety Notes
- Verify the actual terminal layout and wiring diagram for the specific switch before connecting power.
- Confirm the internal LED voltage matches your electrical system before applying power.
- Do not exceed the manufacturer's rated current and voltage.
- Use properly rated and insulated connectors for high-current applications.
- Disconnect power before installation or maintenance.
Industry Knowledge
How Does a Rocker Switch Work?
A rocker switch uses a pivoting actuator mechanism. Pressing one side changes the internal contact position, opening or closing the electrical circuit. In a high-current rocker switch, the contact system and terminal structure are designed to carry the specified electrical load.
Why Choose an Aluminum Rocker Switch?
An aluminum actuator provides a durable metal surface with a clean, premium appearance. It is suitable for equipment where the switch needs to withstand frequent operation while maintaining a professional appearance.
