Abstract
An electrical switch responds to acoustic inputs. A microphone integrated into the electrical switch generates electrical signals in response to the acoustic inputs. A network interface integrated into the electrical switch provides addressable communication with controllers, computers, and other networked devices. The electrical switch may thus be installed or retrofitted into the electrical wiring of all homes and businesses. Users may thus speak voice commands, which are received by the electrical switch and sent for voice control of appliances and other automation tasks.
Claims20
An electrical switch, comprising:
- a toggle switch adapted for a connection to an electrical power, wherein switching of the toggle switch from a first position to a second position creates one or more sounds that overlap with one or more audible frequencies of a human voice;
- a microphone;
- a hardware processor;
- and
- a memory device, the memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations comprising:
- converting the electrical power into a direct current electrical power for use in powering the microphone;
- filtering an analog output signal generated by the microphone, the filtering comprising filtering out the one or more sounds that are created by the switching of the toggle switch from the first position to the second position, the filtering resulting in a filtered analog output signal;
- converting the filtered analog output signal into a digital signal;
- and
- sending the digital signal via a network to a network address associated with a controller.

An electrical switch, comprising:
- a housing retaining a switch assembly therein, wherein the switch assembly is adapted for physical connections to conductors of an electrical power distribution system, and wherein electrical switching by the switch assembly creates one or more sounds that overlap with one or more audible frequencies of a human voice;
- a microphone at least partially housed within the housing, the microphone having a sensory element;
- a hardware processor housed within the housing;
- and
- a memory device housed within the housing, the memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations comprising:
- converting an alternating current electrical power when present on the conductors into a direct current electrical power for use in powering the microphone;
- filtering analog output signal generated by the microphone, the filtering comprising filtering out the one or more sounds that are created by the electrical switching, the filtering resulting in a filtered analog output signal;
- converting the filtered analog output signal into a digital signal;
- and
- sending the digital signal via a network to a network address associated with a controller.
