Overview Upgrade your vehicles setup with the Diode Dynamics D-Switch! Dedicated Backlight Channel. Unlike other 8-button controllers, the D-Switch includes a 9th button for the dedicated backlight bus bar, providing eight extra outputs for accent lighting. Activate all backlit accessories with a single press, freeing up main outputs for other functions. Dynamic Channel Assignment. Unlike one-to-one switch panels, the D-Switch allows multiple output channels per button, giving you complete control over your setup. You can also assign multiple functions of an output to different buttons, such as configuring one button for flashing and another for full power of the same light. Fast, Responsive Bluetooth App. Control and configure settings using the Bluetooth app for iOS and Android, which delivers instant response, no lag, and seamless programming. OEM Signal Integration. Three trigger wires are included to automatically activate your outputs with vehicle signals such as high beams, fog lights, or reverse lights. The ignition wire powers the controller when the vehicle starts, shutting it down automatically when turned off. The Night Mode wire adjusts output settings and controller brightness for low-light conditions. Solid-State, Durable Design. No mechanical relays to wear out or physical fuses to replace!
