US Patent 8173920 Load control device having a modular assembly

A load control device has a modular assembly to allow for easy adjustment of the aesthetic and the color of the load control device after installation. The load control device comprises a user interface module and a base module. The user interface module includes an actuation member for receiving a user input and a visual display for providing feedback to the user. The base module has a controllably conductive device and a controller for controlling the amount of power delivered from an AC power source to an electrical load. A connector of the base module is adapted to be coupled to a connector of the user interface module, such that the controller is operatively coupled to the actuation member and the visual display.
