Rocker Switch Drawing
What is a Wired Rocker Switch?
A wired rocker switch is a pre-terminated electrical control component featuring integrated lead wires for simplified installation. This KCD4 series model uses a pivoting "rocker" mechanism to manage power flow. Unlike standard terminal switches, this version comes with 15cm wires that are internally sealed with epoxy resin, providing superior IP65 waterproof protection and a "plug-and-play" experience for industrial wiring systems.
Industrial Product Overview
The FILN FL3-KCD4-0125-21 is a high-performance wired rocker switch designed for rapid deployment in demanding environments. Featuring a standard 30x22mm rectangular mounting hole and a framed design, it offers a sleek transparent plastic surface that is both fashionable and easy to clean. This switch is pre-wired with 4 leads, allowing for immediate connection without crimping terminals. With certifications like UL, CE, VDE, and ISO9001, it supports 5V-24V or 110V-220V applications. The illuminated KCD4 design ensures high visibility in dark environments, while the sealed tail design provides excellent moisture resistance for outdoor use.

Why Choose Wired Framed Rocker Switches?
FILN's wired rocker switch with a white frame provides the ultimate combination of aesthetics and functionality.
Superior Sealing & Safety
The tail of this switch is glue-sealed to prevent moisture ingress through the wiring path. This, combined with the IP65 rating, makes it perfect for outdoor panels. The framed design ensures the switch sits flush, hiding uneven panel cutouts.
Modern Style & Ease of Use
The transparent plastic surface is not only stylish but also remarkably easy to maintain. Unlike matte finishes, it doesn't trap oils. The illuminated KCD4 design provides a bright guide in pitch-black conditions, unlike non-lighted black switches which are better suited for versatile, well-lit panel designs.
Industrial & Commercial Applications
This wired rocker switch is widely used in power control for any electrified equipment requiring a reliable ON-OFF toggle:
- Outdoor Equipment: Marine dashboards, irrigation controls.
- Commercial Kitchens: Deep fryers, ovens, and blenders.
- Medical Systems: Sterilizers, nursing beds.
- Power Distribution: PDU units, industrial control boxes.
- Transportation: RV auxiliary lighting, bus interior controls.
Complete Rocker Switch Wiring Diagram and Connection Guide
A 4 pin rocker switch wiring diagram is essential for managing higher-current loads or providing clear visual feedback in electrical systems. These switches are typically Double Pole Single Throw (DPST) or specialized single-pole configurations that allow the internal lamp to function independently or in synchronization with the connected device. Depending on your requirements, rocker switch wiring can be configured for either "Independent Illumination" (Always On) or "Dependent Illumination" (On when Device is Active).
Option 1: Light On When Device is Operating (Dependent Illumination)
This configuration is ideal when you need a visual status indicator to show that the equipment is currently powered. In this mode, the internal LED only illuminates when the switch is toggled to the "Press" position.
- Input Connection: Connect the positive (+) and negative (-) wires from the power source to the bottom set of pins.
- Output Connection: Connect the positive and negative terminals of your device to the top set of pins.
- Logic: When the switch is closed, current flows through the device and simultaneously completes the internal circuit for the LED lamp.
Figure 1: Wiring for LED illumination during device operation.
Option 2: Switch Light Remains Constantly Lit (Independent Illumination)
This setup is useful for locating the switch in dark environments (such as vehicle dashboards or industrial control panels). The internal LED remains on as long as the power source is connected, regardless of the device status.
- Input Connection: Connect the power source positive (+) and negative (-) wires to the top set of pins (where the internal lamp is internally bridged).
- Output Connection: Connect the device terminals to the bottom set of pins.
- Logic: The LED is powered directly by the input line, while the rocker mechanism acts as a gatekeeper only for the current flowing to the device.

Comparison of Operation Logic
| Configuration Type | Switch State | Device Status | LED Status |
|---|---|---|---|
| Dependent (Option 1) | Normal | OFF | OFF |
| Press | ON | ON | |
| Independent (Option 2) | Normal | OFF | ON |
| Press | ON | ON |
Technical Considerations & Safety Notes
- Pin Orientation: 4-pin rocker switches usually have two parallel circuits. Ensure you are wiring the positive and negative on the correct pairs to avoid a short circuit.
- Voltage Matching: Check if the internal lamp is designed for 12V DC or 110V/220V AC. Using an AC lamp on a DC circuit will result in no light, while the reverse may cause the lamp to explode.
- Amperage Ratings: Most 4-pin industrial switches (like the KCD4 series) support up to 15A-30A. Verify that your total load does not exceed the manufacturer's specification.
- Termination: Use high-quality 6.3mm female spade connectors. Ensure they are fully insulated to prevent accidental contact between adjacent terminals.
Snap-In Installation Steps
- Panel Cutout: Prepare a 30mm x 22mm rectangular hole in your mounting panel.
- Switch Placement: Pass the 15cm lead wires through the hole first.
- Secure Mounting: Push the switch body into the cutout. The snap-in side clips will lock it firmly to the panel.
- Final Wiring: Connect the 4 pre-stripped wires to your power source and load according to the wiring diagram. No terminal crimping required!
