The Diode Dynamics D-Switch 8-Channel Switch Panel (DD8373) from Nomadic Supply Company® gives full, customized control over any 12V accessory. Unlike other switch panels, our engineers have tailored the D-Switch to be the most functional and effective controller possible while keeping the unique needs of lighting setups in mind. Our Diode Dynamics D-Switch 8-Channel Switch Panel provides a clean installation, unrivaled in-app customization, and the quality you expect from Diode Dynamics. Take your vehicle’s setup to the next level with the Diode Dynamics D-Switch. The Diode Dynamics D-Switch features four 30A outputs and four 15A outputs, putting it solidly into the “serious” category for total power delivery, but it’s packed with all kinds of other features to customize your setup!
Trail-ready control just hit a whole new level. The D-Switch is now Apple CarPlay compatible, giving you seamless control of your offroad lights and powered accessories right from your vehicle’s touchscreen. Whether you’re dialing in your setup at camp, managing lights on the trail, or cleaning up the clutter in the cab, the D-Switch delivers a more integrated way to run your setup. Already running a D-Switch? Existing owners can unlock Apple CarPlay compatibility with a quick app update, no new hardware required. With powerful customization, clean integration, and now Apple CarPlay compatibility, the D-Switch continues to set the standard for modern auxiliary lighting control.
Apple CarPlay and Android Auto Compatibility:
The D-Switch now gives you even more ways to control your setup with compatibility for Apple CarPlay and Android Auto. Once your D-Switch is configured through the Bluetooth App, you can access your custom button layout directly from your vehicle’s infotainment screen for convenient in-dash control of all nine channels. Custom button names, images, unit names, and button colors carry over from the app, giving you a familiar control experience whether you’re using the physical controller, your phone, or your vehicle’s display.
Dedicated Backlight Channel:
While there are many 8-button controllers on the market, the D-Switch stands apart with a 9th button dedicated to the backlight bus bar. The backlight bus provides eight extra outputs for your accent lights, allowing you to connect all of your backlit accessories without using up any of your main outputs. With just the press of a button, you can now activate all of your backlights at once! This is a game-changer for any rig with multiple lights installed.
Dynamic Channel Assignment:
The Diode Dynamics D-Switch is designed to give you complete control over your vehicle’s setup with eight customizable output channels. Unlike traditional switch panels that are one-to-one, meaning Channel 1 is always tied to Button 1, the D-Switch allows you to group and configure multiple output channels per button, allowing you to control multiple outputs with a single button. You can also power a single output with the different strobing patterns that are included. For example, you can program one button to strobe light and another to run that same light at full power. Whether you’re running Diode Dynamics off-road lighting or any other 12V accessories, the D-Switch allows you to customize each button to do exactly what you need.
Fast, Responsive Bluetooth App:
To activate and use the D-Switch, you can use the included controller, or control it using your phone through the Bluetooth App. That’s where you’ll configure and customize things as well. Say goodbye to switch panel apps that lag, freeze, or don’t connect. The Diode Dynamics D-Switch Bluetooth app for iOS and Android delivers instant response and easy programming with no loading screens or connection delays for a seamless and fast experience, every time.
OEM Signal Integration:
The Diode Dynamics D-Switch includes four trigger wires, along with a dedicated Ignition wire for added flexibility. This allows you to control your whole setup using vehicle signals, for a completely integrated experience. The ignition wire can be wired into an OEM ignition source and will activate the D-Switch when the ignition is turned on. It will also shut things down when the ignition is turned off. No need to manually turn your panel off! If you want to use any outputs without the ignition turned on, no worries – you can still turn the controller on manually at any time. The three trigger wires provide seamless integration with any of your vehicle’s 12V factory signals, such as high beams, fog lights, or reverse lights. This allows you to activate your outputs automatically-no buttons or switches. With some simple programming, your entire setup can operate like it’s fully integrated into your vehicle. Lastly, the Night Mode wire can be used to activate certain outputs, such as dimming outputs, or adjusting settings for low-light conditions. This trigger also adjusts the brightness of the controller’s backlighting automatically when driving at night.
Solid-State, Durable Design:
Built for extreme durability, the D-Switch features a solid-state design with no mechanical relays to wear out, or physical fuses to replace. The hub is encapsulated with an aluminum heatsink, ensuring superior heat dissipation. The D-Switch is IP67-rated for weather resistance and is backed by a 3-year limited warranty, ensuring long-term reliability and performance. Whether you’re off-roading or on the road, it’s built to withstand whatever you throw at it.
