FILN Inline Cord Box Waterproof Switch 30A KCD4 Aluminum Rocker

Convenience and safety in power control often mean having a switch right where you need it, but what happens when a wall-mounted panel is not an option? For portable equipment, power tools, and outdoor lighting, you need control directly on the power line. However, typical cheap, plastic cord switches are flimsy, low-amperage, and certainly not waterproof. They represent a significant weak point, prone to failure from water, dust, or simple wear and tear.

This is where a professionally engineered solution is required. You need a heavy-duty Inline Cord Box Waterproof Switch designed to withstand real-world use.

We are proud to introduce the FILN KCD4 model, the ultimate inline control solution. This product combines the go-anywhere convenience of a cord switch with the immense power (30A), rugged durability (IP66), and premium style (brushed aluminum) of a high-end industrial component.

What is an Inline Cord Box Waterproof Switch?

An Inline Cord Box Waterproof Switch is a specialized, fully sealed enclosure designed to be integrated directly along a heavy-duty electrical cable. Unlike a surface-mounted junction box, which terminates wiring on a wall or panel, an inline switch interrupts the cord itself.

This allows you to add a robust, safe, and reliable ON-OFF switch to any existing power cord. The process is simple: you cut the cord, wire each end to the secure terminals inside the box, and seal the unit. The result is a seamless, factory-quality switch that gives you direct control over any device plugged in at the end of the line. This approach eliminates the need for extra electrical boxes or complex panel wiring, providing control exactly where it’s needed most.

Built for Heavy-Duty Performance

This FILN model is engineered from the ground up to handle demanding tasks and harsh environments.

Massive 30A Power Handling

This is not a lamp switch. The internal KCD4 aluminum rocker switch is rated for a massive 30 Amps. This high-current capacity means this Inline Cord Box Waterproof Switch can safely manage the power draw of professional equipment without overheating or failing. It is ideal for controlling:

• High-power industrial tools and machinery
• Large water pumps and compressors
• Professional-grade pressure washers
• Heavy-duty outdoor and landscape lighting

IP66 Weatherproof Durability

The rugged enclosure is sealed to an IP66 rating, offering complete protection for the internal wiring. This means the unit is fully dust-tight and can withstand powerful water jets from any direction. This level of durability makes it the perfect switch for outdoor job sites, marine applications, workshops, and any environment where moisture and debris are a constant concern.

Secure Cord Grip & Strain Relief

A key feature of any quality inline switch is its cable entry points. The watertight cable glands on this box not only keep moisture out, but they also grip the cord securely. This provides critical strain relief, ensuring the cable cannot be accidentally pulled out or put stress on the internal electrical connections.

Premium Design & User-Friendly Features

While built for toughness, this Inline Cord Box Waterproof Switch also incorporates high-end features for a superior user experience.

Multiple Brushed Aluminum Face Options

The powerful 30A rocker switch features a stylish and durable aluminum face. To match your equipment or aesthetic preference, it is available in three different brushed metal finishes. This allows you to choose a look that ranges from ruggedly industrial to professionally sleek, a significant upgrade over standard plastic switches.

Optional LED Status Illumination

For enhanced safety and convenience, the switch can be configured with a built-in LED indicator light. Available in five colors (Red, Green, Yellow, Blue, and White), the light provides a clear, at-a-glance “power on” status—a critical feature when operating powerful machinery from a distance.

Fast and Secure Screw Terminals

Inside the sealed enclosure, the switch is equipped with heavy-duty screw terminals. This allows you to easily and securely attach the wires of the power cord, ensuring a solid, reliable connection that can safely handle the full 30A current and withstand vibration.

Applications & Use Cases

The unique inline design of this switch opens up a world of practical applications:

• For Professionals: Add a waterproof switch directly to the power cord of a concrete mixer, a high-power tile saw, or an industrial vacuum for convenient control on the job site.
• For Outdoor Use: Create your own custom, heavy-duty switched extension cord for managing landscape lighting, pond pumps, or outdoor event equipment.
• For the Workshop: Install a convenient ON/OFF switch on the cord of a table saw, drill press, or other stationary power tool that has an awkwardly placed factory switch.

Stop settling for flimsy cord switches that can’t handle the job. Take direct, safe, and reliable control of your heavy-duty equipment.
