What are Junction Boxes Electrical with Rocker Switches?
Junction boxes electrical are protective enclosures designed to house wiring connections and control interfaces, shielding them from environmental hazards such as moisture, dust, and physical impact. When integrated with a rocker switch or metal push button, these units serve as centralized control points for industrial and outdoor machinery. The WB1-2T-FLM19 model specifically combines a rugged black polymer housing with a high-performance 19mm metal button, offering a localized power management solution that ensures both electrical safety and operational durability in demanding environments.
Product Overview
The WB1-2T-FLM19 is a premium waterproof junction box with switch designed by FILN for high-current industrial applications. This unit features a 19mm metal rocker switch (push-button style) capable of handling up to 20A. Certified with ISO9001, CE, VDE, RoHS, SGS, UL, and IP65, it provides a safe enclosure for momentary metal button control boxes and latching illuminated switch boxes. Whether used in outdoor lighting, marine power distribution, or industrial machinery, this black waterproof junction box 12v/220v offers superior protection. The bright LED ring illumination (available in R/G/Y/B/W) ensures high visibility in dark or complex industrial settings

INSTALLATION GUIDE
- Prepare the junction box panel by ensuring the 19mm hole is pre-drilled.
- Insert the metal push button switch through the front of the panel.
- Secure the switch from the back using the provided hex nut.
- Connect the 4PIN wire harness to your power source and load.
- Assemble the waterproof junction box to complete the installation.
4 Pin Push Button Switch Wiring Diagram
A 4-PIN switch consists of two parts: Switch Contacts (to control the device) and LED Terminals (marked with + and -). Below are two ways to wire the LED indicator.
- Horizontal Pins: The switch mechanism (Power In / Load Out).
- Vertical Pins (+ / -): The LED indicator light terminals.
Method 1: LED Synchronized with Device (On when Active)
Logic: The button light only turns ON when the device is running. It serves as a "Status Indicator."
- Wiring: Connect LED (+) to the Output side of the switch. LED (-) to Power Negative.
- Applications: Power start buttons, car fog lights, industrial machinery.
- Benefit: Saves power; provides visual feedback that the system is active.
Figure 1: LED turns ON only when button is pressed
Method 2: LED Always ON (Backlight Mode)
Logic: The button light stays ON constantly as long as there is power, regardless of the button position.
- Wiring: Connect LED (+) directly to the Power Positive. LED (-) to Power Negative.
- Applications: Dark environments, hallway switches, standby power indicators.
- Benefit: Allows you to find the switch easily in total darkness.

| Mode | LED Status (Idle) | LED Status (Pressed) |
|---|---|---|
| Sync (Status) | OFF | ON |
| Always ON (Backlight) | ON | ON |
INDUSTRY KNOWLEDGE
What is a Junction Box Electrical System?
A junction box is an enclosure housing electrical connections, designed to protect them from weather and accidental contact. In our configuration, combining a waterproof-junction-box-with-switch provides a ready-to-use control station that prevents short circuits caused by moisture or dust ingress.
Momentary vs. Latching: Which do you need?
| Feature | Momentary (Pulse) | Latching (Maintain) |
| Action | Springs back when released | Stays in place when pressed |
| Common Use | Horns, Doorbells, PC Reset | Light Switches, Main Power |
