Integrated spdt or dpdt switch with spdt relay combination for use in residence automation

Abstract

Method and apparatus for integrating one of single and plurality of hybrid SPDT or DPDT switch with one of SPDT and DPDT relay via contactors structured to connect the poles of the relay and the switch directly or via conductive structures including PCB assembly, for operating electrical appliances via the switch manual key and remotely by powering the relay coil having latching or non-latching armature, with a CPU program providing the manual key and the manual keys of each SPDT or DPDT connected in a traveler lines to the integrated switch-relay to switch on-off group of loads and all the loads of home automation network or grid via optical cable, RF, IR in line of sight and bus line.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention is related to electrical automation devices including switches and relays for manual and remote operation of appliances in residences and other buildings.[0003]2. Description of the Prior Art[0004]Switches and relays for switching on-off electrical appliances such as water boiler, air conditioners, heaters, lights and any other electrical equipment and appliances in residences, offices, public building, businesses, restaurants and factories are very well known. The well known relay devices for home automation are commonly installed in the main or a sub electrical cabinet of a given premises. The installed relays are operated via bus lines, RF, or by control signal propagated via the AC power line.[0005]The costs of the prior known automation devices and relays including their installation are very high because the electrical wiring must be changed from its standard commonly applied wiring systems, in whic...

AI Technical Summary

Benefits of technology

The present invention provides a hybrid switch that can be fitted with different key levers and allows for the selection of a wide variety of levers and decorative covers. This solves the difficulty of matching different AC switch designs, their panel colors, and decorations. Additionally, the invention allows for the identification of the on-off status of appliances without requiring the transmission of all the manual switch's positions and the relay's data to the controller. This simplifies data handling and reduces operational complications.

Problems solved by technology

The costs of the prior known automation devices and relays including their installation are very high because the electrical wiring must be changed from its standard commonly applied wiring systems, in which the electrical power is fed via the commonly installed switches in the electrical wall boxes.

Such fundamental basic change in the structured electrical systems became too complex, costly and moreover the complexity is the cause for serious repeated malfunctions of the installed electrical automation systems.

Further, the known home automation devices do not report the power consumed by the individual electrical appliances and do not provide usable data for reporting statistics to the home owners, nor to the yet to be born “smart grid”.
