What are 12 Volt Rocker Switches?
12 volt rocker switches are specialized electromechanical components designed to control the flow of electricity within low-voltage DC circuits, commonly found in automotive, marine, and industrial battery-powered systems. The FL3-KCD4-030-23 model is a 30X22MM rectangular switch that utilizes a "rocking" mechanism to transition between circuit states. These switches are engineered for high-capacity loads, supporting up to 30A 250VAC, making them ideal for heavy-duty power management. Whether configured as a standard ON-OFF or a complex 6-pin DPDT ON-OFF-ON, these switches provide reliable tactile feedback and optional LED illumination for status indication in dark environments.
Product Overview
The FILN 12 volt rocker switches series represents the industry standard for KCD4 rectangular switches. Featuring a robust 30X22MM mounting size, this switch is designed for seamless snap-in installation. Our products carry prestigious international certifications, including ISO9001, CE, VDE, RoHS, SGS, UL, and IP65, ensuring safety and performance compliance across global markets. These 6-pin switches are frequently utilized in industrial machinery, kitchen appliances, and automotive dashboards. The split-body design allows for maximum heat dissipation and handles high-current surges up to 30A. The integrated LED light (available in R/G/Y/B/W) acts as a high-visibility locator, enhancing operational safety in low-light conditions.

Industrial & Household Applications
From 12v marine systems to high-voltage industrial control panels, 12 volt rocker switches are ubiquitous. They serve as the primary power interface for water dispensers, air fryers, and medical diagnostic equipment. In the automotive sector, they are the backbone of RV lighting and winch control systems.
Installation & 6-Pin Wiring Guide
- Panel Cutout: Prepare a precise 30X22MM rectangular opening.
- Snap-In Mounting: Insert the switch from the front; the side clips will lock it securely.
- Central Power: Connect the positive feed to the middle terminals (Common).
- Load Connection: Connect Device 1 to the top pins and Device 2 to the bottom pins.
- LED Grounding: For lighted models, connect the negative terminal to the ground pin to activate the internal lamp.
Complete 6 Pin Rocker Switch Wiring Diagram and Connection Guide
A 6 pin rocker switch wiring diagram is a vital resource for complex electrical systems requiring the simultaneous control of two separate circuits or the reversal of motor polarity. This 6-pin configuration typically functions as a Double Pole Double Throw (DPDT) switch. It is frequently used in industrial machinery, automotive power windows, and marine equipment where multi-device management is required from a single control point. This wiring schematic is universal and applies to both illuminated (lighted) and non-illuminated 6-pin rocker switches.
How to Wire a 6 Pin Rocker Switch: Connection Steps
According to the technical schematic, a 6-pin switch features two independent columns of terminals. Follow these steps to ensure a correct and safe connection for both lighted and non-lighted models:
- 1. Central Power Input: Connect the positive (+) wires from your power source to the middle pair of pins. These terminals act as the common feed for the entire switch.
- 2. Device 1 Connection (Up Position): Connect the top pair of pins to the terminals of your first device (Device 1). When the rocker is toggled to the "Up" position, the circuit to Device 1 is closed.
- 3. Device 2 Connection (Down Position): Connect the bottom pair of pins to your second device (Device 2). Toggling the switch to the "Down" position redirects power to this device.

4. Grounding and Illumination:
- For Illuminated Switches: The negative (-) wire must be connected to the dedicated ground pin (often indicated by a different color or label) to power the internal LED. In many DPDT configurations, the lamp remains lit to act as a locator light.
- For Non-Illuminated Switches: Connect the negative (-) wires from both Device 1 and Device 2 directly back to the negative terminal of the power supply. The switch body itself does not require a ground connection.
Switch Operation and Load Logic
| Switch State | Device 1 Status | Device 2 Status | LED Status (If Lighted) |
|---|---|---|---|
| UP Position | ON (Active) | OFF | ON |
| Normal (Middle) | OFF | OFF | ON (Constant) |
| DOWN Position | OFF | ON (Active) | ON |
Technical Considerations and Precautions
- DPDT Versatility: Because a 6-pin switch handles two independent poles, it can be used for dual-circuit control or to create a polarity-reversal circuit (enabling forward and reverse motor directions).
- Voltage and Amperage: Ensure the switch is rated for your load. Industrial 6-pin switches (like the KCD4 series) are often rated for 15A 250VAC. Overloading terminals can lead to contact welding.
- Internal Lamp Compatibility: If using an illuminated rocker switch, confirm whether the lamp is rated for DC (12V/24V) or AC (110V/220V) to avoid damaging the internal indicator.
- Terminal Security: Use insulated crimp connectors. Given the pin density, insulation is critical to prevent accidental bridging and short circuits between the two poles.

How Does a 6-Pin DPDT Rocker Switch Work?
A Double Pole Double Throw (DPDT) rocker switch operates as two separate switches controlled by a single actuator. Internally, a pivoting metal "rocker" bridges the connection between the common center pins and either the top or bottom output pins. In a 12 volt rocker switches configuration, this allows for the simultaneous control of two different circuits or the reversal of polarity for DC motors, which is essential for winches and linear actuators. The use of silver alloy contacts ensures that the switch can handle high inrush currents without "welding" the contacts together.

Frequently Asked Questions (FAQ)
1. What is the difference between a 3-pin and 6-pin 12V rocker switch?
A 3-pin switch is usually SPST (Single Pole) used for simple ON-OFF. A 6-pin switch is DPDT (Double Pole), allowing it to control two circuits or reverse motor polarity.
2. Can I use this 12 volt rocker switch for 220V AC applications?
Yes, the KCD4 model is rated for up to 250VAC at 30A. However, ensure the internal LED voltage matches your power source.
3. How do I wire a 6-pin illuminated rocker switch?
Connect power to the center pins. Output to the top/bottom pins. The specific ground terminal must be connected to the negative line to light the LED.
4. What does the "Momentary" (ON) function mean?
A momentary switch stays active only while you hold it down. Once released, it springs back to the OFF position.
5. Is the KCD4 switch waterproof for marine use?
This specific model is not natively waterproof but can achieve IP65 rating when paired with our custom-fit rubber waterproof cover.
6. What is the maximum current this switch can handle?
The FILN KCD4 heavy-duty series can handle a maximum current of 30A 250VAC.
7. Do you offer custom wire harnesses for these switches?
Yes, FILN provides full customization, including pre-soldered wires and specific connectors (XH, Molex, etc.).
8. Why is the 30X22MM size so common?
It is a global industrial standard size for rectangular rocker switches, ensuring compatibility with most pre-existing panel cutouts.
9. Can the LED light stay on even when the switch is OFF?
Yes, by wiring the LED power pins directly to the constant power source, it can function as a permanent locator light.
10. Does FILN provide certifications for export?
Yes, we provide CE, UL, RoHS, and VDE certificates required for European and North American markets.
