Rocker Switch Technical Drawing
What is a 120V Rocker Switch with Stainless Steel Surface?
A 120V rocker switch is an electrical control component designed to open or close a circuit through a rocking motion. The FL3-KCD4-0324-21 model features a premium stainless steel surface, providing a modern, high-end aesthetic while ensuring superior durability. This KCD4 rocker switch is specifically engineered for 30x22mm panel cutouts, common in industrial machinery and commercial appliances. The stainless steel face is not only fashionable but also incredibly easy to clean and maintain, making it ideal for environments where hygiene and aesthetics are prioritized. With a DPST 4-pin configuration, it provides secure dual-pole switching for 120V or 220V power systems.
Product Overview
The FILN 120V rocker switch is a versatile power control solution certified by ISO9001, CE, VDE, RoHS, SGS, UL, and IP65. Designed for high-performance applications, this waterproof 4 pin rocker switch supports currents up to 30A, making it suitable for heavy-duty industrial DPST power control. The stainless steel surface rocker switch for appliances offers a split-design with an internal frame for enhanced mechanical stability. Whether utilized in outdoor power tools, kitchen equipment, or medical devices, the illuminated KCD4 rocker switch ensures visibility in dark environments through its R/G/Y/B/W LED options.

The Advantage of Stainless Steel Face & Internal Framing
FILN's KCD4 30x22mm rocker switch is designed for premium performance. The stainless steel surface offers a significant upgrade over standard plastic switches: it is resistant to corrosion, easy to clean, and provides a sleek, modern finish that enhances the value of any device. Furthermore, the split-design with an internal frame provides structural "exoskeleton" support, preventing the switch body from cracking or losing its tension in tight panel cutouts. This internal frame also ensures the IP65 rubber seal remains compressed and effective throughout the switch's lifespan.
Global Applications
Because of its 30A high current rocker switch rating and waterproof outdoor rocker switch capabilities, this KCD4 model is used globally in:
- Food Service: Ovens, air fryers, and coffee machines.
- Industrial Control: Power distribution units and cabinets.
- Outdoor Equipment: Cleaning machines and marine panels.
- Commercial Hardware: Vending machines and POS systems.
Installation Guide
- Panel Cutout: Create a precise 30x22mm opening in the mounting surface.
- Insertion: Push the rocker switch through the panel from the top.
- Snap-In: Utilize the dual-side snap-in clips to lock the switch firmly.
- Wiring: Connect the 4-pin quick terminals according to your circuit requirements.
4 Pin Rocker Switch Wiring Diagram & Connection Guide
A 4 pin rocker switch wiring diagram is essential for managing higher-current loads. These switches are typically Double Pole Single Throw (DPST). Depending on your needs, choose between two wiring options:
Option 1: Light On When Device is Operating (Dependent)
The LED only illuminates when the switch is toggled to the "ON" position.
- Input: Power (+) and (-) to bottom set of pins.
- Output: Device terminals to top set of pins.
Option 2: Switch Light Remains Constantly Lit (Independent)
The LED remains on as long as the power source is connected (Switch Finder Mode).
- Input: Power (+) and (-) to top set of pins.
- Output: Device terminals to bottom set of pins.
