Electronic switching device and system

An electronic wave switch device for controlling a load, the device comprising:

• a housing assembly including a front cover assembly having a user interface, a back body assembly, a ground clip extending from the back body assembly, and a plurality of terminals configured to be coupled to an AC power source and the load, wherein the housing assembly is configured to be inserted into and mate with a frame coupled to a device wall box;
• and
• a circuit assembly disposed inside the housing assembly coupled to the plurality of terminals, the circuit assembly comprising a printed circuit board, the printed circuit board including a sensor coupled to a processor, wherein the sensor is configured to receive and detect an input stimulus in response to movement of an object a predetermined distance from the sensor, and wherein the processor is configured to propagate a switch actuation command in response to detecting the input stimulus, wherein the circuit assembly is electrically referenced to the ground clip, wherein the ground clip is positioned to engage with the frame when the housing assembly is mated with the frame.
