Waterproof Inline Switch 30A High Current Switch IP65 KCD4 Rocker Switch | FILN
Détails du produit
The waterproof inline switch from FILN combines a heavy-duty 30A KCD4 rocker switch with a sealed protective enclosure for electrical control in outdoor, marine, RV, automotive, industrial, and other moisture-prone environments. Unlike multi-switch waterproof boxes, this version uses a single switch opening, providing a compact inline control solution when only one high-current switch is required.
The enclosure is designed to protect the switch and wiring connection from dust, water spray, humidity, and accidental contact. With an IP65 waterproof design, PG9 cable gland, 4-pin screw terminals, and 30A high-current switching capability, this waterproof inline switch is suitable for applications where reliable switching and environmental protection need to be combined in one compact assembly.
Quick Answer: This waterproof inline switch is a single-hole waterproof switch assembly using a 30A KCD4 rocker switch. It is designed for inline electrical control where the switch, wiring terminals, and cable entry need additional protection from outdoor moisture and dust. 30AHigh-Current Switching IP65

What Is a Waterproof Inline Switch?
A waterproof inline switch is an electrical switching assembly designed to be installed directly along a wiring route rather than mounted as an exposed switch on a control panel. The protective enclosure surrounds the switch and wiring area, helping reduce exposure to water, dust, humidity, and accidental mechanical contact.
This FILN version combines a 30A KCD4 rocker switch with a sealed enclosure. The single-hole configuration is particularly useful when an application needs one independent ON-OFF control instead of a multi-switch control box.
Why Use an Inline Waterproof Switch?
- Provides a protected switching point along an electrical cable or equipment wiring route.
- Helps protect switch terminals from outdoor moisture, dust, and water spray.
- Combines a high-current 30A rocker switch with a protective enclosure.
- Uses a single switch opening for a compact and simple installation.
- Suitable for equipment where a conventional exposed rocker switch is not sufficiently protected.
- Can be supplied for OEM and B2B applications with customization options.
Single-Hole Waterproof Switch Design
The main difference between this version and a double-opening waterproof switch box is the number of switch positions. This product is designed around one KCD4 rocker switch, creating a more compact control solution for equipment that only requires one ON-OFF function.

How to Install a Waterproof Inline Switch
1. Install the KCD4 Rocker Switch
The KCD4 rocker switch uses a snap-in mounting structure. Confirm the required 22×30mm mounting cut-out and align the switch with the correct ON/OFF orientation before pressing it into position.
- Confirm the 22×30mm panel opening.
- Align the KCD4 rocker switch with the opening.
- Press the switch into the opening until the retaining clips engage.
- Check that the switch is firmly seated and does not move excessively.
2. Connect the 4-Pin Screw Terminals
Route the cable through the PG9 waterproof cable gland before completing the wiring. Strip approximately 5–7mm of insulation and secure the conductors in the screw terminals.
- Insert the cable through the PG9 cable gland.
- Strip approximately 5–7mm of insulation.
- Loosen the screw terminals.
- Insert the exposed conductor into the appropriate terminal.
- Tighten the screw securely.
- Verify the circuit connection before energizing the system.
3. Seal the Waterproof Enclosure
After wiring, arrange the internal cables carefully and make sure the sealing components are correctly positioned before closing the enclosure.
- Arrange the internal wiring without pinching the cables.
- Check the enclosure gasket and sealing surfaces.
- Close the waterproof enclosure.
- Tighten the enclosure screws evenly.
- Tighten the PG9 cable gland to compress the cable seal.
- Inspect the enclosure for visible gaps before use.
Waterproof Inline Switch Wiring Guide
A 4-pin rocker switch can be configured for different illumination behaviors depending on the internal lamp connection and the selected electrical circuit. Always confirm the actual terminal configuration and lamp voltage of the supplied switch before wiring.
Option 1: LED Turns On When the Device Is Operating
In a dependent illumination configuration, the LED indicates that the switched load is active. When the rocker switch is turned ON, the load circuit is energized and the indicator illuminates.
- Input: Connect the power source to the appropriate input terminals.
- Output: Connect the switched output terminals to the load.
- Operation: The LED illuminates when the switch completes the active circuit.
Figure 1: Example wiring for LED illumination during device operation.
Option 2: LED Remains On as a Switch Finder
In an independent illumination configuration, the internal LED can remain illuminated while power is available. This configuration is useful when the switch needs to remain visible in dark environments.
- Power connection: Connect the lamp circuit according to the supplied switch's internal wiring configuration.
- Load connection: Connect the device to the switched terminals.
- Operation: The LED remains illuminated independently of the switched load when correctly configured.

How to Choose the Right Waterproof Inline Switch
| Selection Factor | What to Check |
|---|---|
| Current Rating | Confirm that the load current is within the switch's rated capacity. This version supports up to 30A under the specified rating conditions. |
| Switch Opening | Choose the single-hole configuration when only one rocker switch is required. |
| Protection Rating | IP65 is suitable for dust-tight protection and protection against water jets under specified test conditions. |
| Cable Entry | PG9 cable gland provides a sealed cable entry for the enclosure. |
| LED Voltage | Confirm the required LED voltage and AC/DC configuration before ordering. |
| Connection Method | 4-pin screw terminals provide a secure mechanical connection for the specified configuration. |
How Does a Waterproof Inline Switch Work?
A waterproof inline switch combines three basic functions: electrical switching, cable connection, and environmental protection. The rocker switch controls the electrical circuit, while the enclosure surrounds the switch and connection area. A cable gland provides a controlled cable entry point and helps maintain the enclosure's protection against external contaminants.
In this configuration, the 30A KCD4 rocker switch provides the switching function, while the waterproof housing provides an additional physical barrier around the electrical components. This makes the assembly useful when a conventional exposed rocker switch would be difficult to protect from moisture or dust.
What Does IP65 Mean?
An IP65-rated enclosure is designed to be dust-tight and protected against water jets from any direction under the applicable test conditions. IP65 does not mean the product is designed for continuous underwater immersion. Applications involving submersion require a product with an appropriate immersion protection rating.
Why Is the Single-Hole Design Useful?
A single-hole waterproof inline switch avoids unnecessary unused switch positions. It is a practical configuration for machines, vehicles, marine equipment, outdoor devices, and electrical assemblies that require only one protected ON-OFF control.
