Junction Box Drawing
What is a Small Electrical Junction Box?
A small electrical junction box is a protective enclosure used to house electrical connections, specifically designed to insulate and shield wiring from environmental factors. The WB5-2T-D112 model integrates a KCD1 round waterproof rocker switch, serving as a centralized control point for power distribution in industrial and outdoor settings. It ensures circuit integrity by providing a physical barrier against moisture, dust, and accidental contact.
Product Overview
The WB5-2T-D112 small electrical junction box is engineered for high-performance switching in demanding environments. Featuring a mini KCD1 round waterproof rocker switch, this unit provides a reliable ON-OFF function with high-visibility LED illumination. Certified by ISO9001, CE, VDE, RoHS, SGS, UL, and IP65, FILN ensures each unit meets global safety standards. The core advantage lies in its snap-in installation and 3PIN screw terminals, making it ideal for outdoor lighting, marine equipment, and industrial automation. The bright LED in R/G/Y/B/W colors facilitates rapid status identification in dark industrial workspaces.

Understanding Switch Functions: What is ON-OFF?
| Function Code | Description & Operation |
|---|---|
| ON-OFF (SPST) | Single Pole Single Throw. The most common function for the KCD1 round rocker switch. It maintains its position (maintained action) to either complete or interrupt the electrical circuit. |
| (ON)-OFF (Momentary) | Spring-loaded action where the switch returns to the OFF position immediately after being released. Used for resets or signaling. |

How to Install and Wire a KCD1 Rocker Switch in a Waterproof Junction Box
1. Installing the KCD4 Rocker Switch into the Panel
The KCD4 rocker switch is designed for quick panel mounting with a secure snap-in structure. Follow these steps to properly install the switch into your waterproof junction box panel:
- Locate the standard 22×30mm cut-out on the junction box panel.
- Align the rocker switch with the opening, ensuring correct orientation (ON/OFF marking direction).
- Press the switch firmly into the cut-out until the side retaining clips snap into place.
- Check that the switch sits flush with the panel and does not move or loosen.
This snap-fit design ensures a stable installation without additional screws, making it ideal for industrial and DIY electrical applications.
2. Assembling the Waterproof Junction Box (IP65)
After installing and wiring the rocker switch, complete the assembly of the waterproof junction box to ensure full protection against dust and water.
- Carefully arrange all internal wiring to avoid pinching or interference.
- Place the gasket correctly along the enclosure edge to maintain waterproof sealing.
- Close the junction box lid securely.
- Tighten all enclosure screws evenly to ensure uniform pressure on the seal.
- Firmly tighten the PG9 cable gland nut to compress the sealing ring around the cable.
- Verify that the enclosure meets IP65 waterproof standards with no visible gaps.
Proper assembly is critical to ensure long-term durability, especially in outdoor, humid, or industrial environments.
Detailed 3 Pin Illuminated Rocker Switch Wiring Diagram and Connection Guide
A 3 pin illuminated rocker switch wiring diagram is a fundamental resource for technical personnel designing circuits that require visual status feedback. Unlike standard non-lighted models, an illuminated rocker switch features a built-in lamp that provides instant confirmation of the circuit's state. This guide provides the precise wiring schematic and technical logic required to integrate these components into your power systems.
How to Wire a 3 Pin Illuminated Rocker Switch: Connection Steps
To ensure the internal LED or neon lamp functions correctly alongside your device, follow this specific terminal configuration:
- 1. Power Input (Line Terminal): Connect the positive (+) wire from your power supply to the middle pin of the switch. This terminal acts as the common entry point for the current.
- 2. Load Connection (Device Terminal): Connect the bottom pin to the positive input of your device (e.g., a motor, lamp, or industrial component). When the switch is engaged, current is bridged from the middle pin to this terminal.
- 3. Ground Connection (Lamp Terminal): Connect the top pin (often gold-colored) directly to the negative (-) terminal of the power source. This dedicated connection completes the circuit for the internal light. Without this ground wire, the switch will toggle the device but will not illuminate.
Switch Operation and LED Logic
| Switch State | Device Status | Internal LED Status |
|---|---|---|
| Normal (Off) | OFF (Open Circuit) | OFF (Dark) |
| Press (On) | ON (Closed Circuit) | ON (Illuminated) |
Technical Considerations and Precautions
- Voltage Specificity: Illuminated switches are rated for specific voltages (e.g., 12V DC, 110V AC, or 220V AC). Connecting a low-voltage DC LED switch to high-voltage AC will result in immediate component failure.
- Terminal Identification: Always identify the ground pin (usually brass or gold) before applying power. Incorrectly swapping the positive and ground terminals can lead to a short circuit when the switch is flipped to the "On" position.
- Current Capacity: Verify that the switch’s rated amperage (e.g., 15A 250VAC) is higher than the maximum current draw of your device to prevent terminal overheating or melting.
- Reliable Termination: Utilize high-quality insulated spade connectors or proper soldering to maintain a low-resistance connection, ensuring long-term electrical stability.
