US Patent 9832841 Wall-plate-switch system and method

In one example, a wall plate may have or include an electrical circuit. The electrical circuit may include a switch and a light sensor supported on a base in the form of a circuit board. A switch cover may cover the light sensor and selectively move with respect to the base through a first range of motion. The switch cover may actuate the switch, when moving through the first range of motion. Additionally, the switch cover may be transparent or semitransparent to enable light to pass through and reach the light sensor regardless of where the switch cover is within the first range of motion.
