Rocker Switch Drawing
What is a Boat Rocker Switch?
A boat rocker switch is a heavy-duty electrical toggle designed specifically for marine environments, such as yachts and ships. The KCD4 series features a robust rectangular body and a SIDE LIGHTS symbol illuminated surface, allowing operators to identify functions quickly via laser-etched icons that glow when active. This 5-pin configuration is optimized for 12V-24V systems, ensuring reliable power management for bilge pumps, lighting, and navigation equipment.
Industrial Yacht Switch Overview
The FILN FL3-KCD4-0401-21L is a premium boat rocker switch featuring a standard 1.46"×0.83" (37mm×21mm) mounting cutout. This model is distinguished by its high-quality ABS+PC black actuator surface with a SIDE LIGHTS laser-etched symbol that illuminates in a brilliant Blue Dual LED. Built for the marine industry, it offers a 2-position ON-OFF SPST function with a 5-pin terminal layout at the rear. The illuminated KCD4 design provides critical visibility in dark cabins or night-time sailing, while the smooth surface is fashionable and easy to clean, resisting salt spray and industrial grime.

Details: Internal Switch Mechanism
This rocker switch is made from high-quality ABS and PC materials and features a strong internal mechanism designed for long-lasting performance. It has been tested to endure 10,000 presses during normal use, ensuring reliable and consistent operation for your accessories.
Professional Installation Steps
- Cutout Preparation: Create a 37mm x 21mm (1.46" x 0.83") rectangular hole in the yacht's dashboard.
- Switch Positioning: Align the switch actuator with the "SIDE LIGHTS" symbol facing the desired orientation.
- Snap-In Mounting: Push the switch body into the hole from the front. The side-mounted dual clips will lock the switch firmly.
- Wiring: Connect your wires to the 5-pin terminals. Use the provided 14AWG wires for high-current paths.
Professional 5 Pin Rocker Switch Wiring Diagram Guide
A 5-pin rocker switch is a versatile Single Pole Double Throw (SPDT) switch commonly used in marine and automotive applications. It features built-in LEDs that can be configured to act as status indicators or dashboard backlights. Below is the technical breakdown of the pin layout and the two primary wiring methods.
Pin Terminal Layout Definitions:
- Pin 2: Main Power Input (+)
- Pin 3: Load Output to Device (+)
- Pin 6: Positive Terminal for LED Indicator (+)
- Pin 7: Ground Terminal for LED (-)
- Pin 8: Jumper Terminal (Commonly jumped to Pin 7 for dual LED grounding)
Option 1: Light On with Switch
In this configuration, the switch LED only illuminates when the connected device is powered ON. This is ideal for identifying active loads.
- Connect the Power (+) source to Pin 2.
- Connect Pin 3 to the positive terminal of your device.
- Bridge Pin 6 to Pin 3. This ensures the LED only receives power when the switch is closed.
- Connect Pin 7 to the Negative/Ground (-) terminal.
- Jump Pin 8 to Pin 7 to complete the internal LED circuit.
Option 2: Constant Background Light
The LED remains illuminated as long as the battery is connected. This is perfect for "Background Lighting" to locate switches in total darkness.
- Connect the Power (+) source to Pin 2.
- Connect Pin 3 to the positive terminal of your device.
- Bridge Pin 6 to Pin 2. This provides the LED with constant power regardless of switch position.
- Connect Pin 7 to the Negative/Ground (-) terminal.
- Jump Pin 8 to Pin 7 to ensure both internal icons have a ground path.
Technical Note: Always use a 14-16 AWG wire for high-current accessories and ensure an inline fuse is installed between the power source and Pin 2 for maximum safety compliance (UL/CE standards).
