Abstract
A remote light control for homes, offices or factories consists of a radio transmitter which may be carried on the person or in an automobile and a coacting radio receiver which may be installed permanently as a part of the building wiring, or as a portable unit may be plugged into an outlet in the home or other building as an accessory. A step-down transformer and an associated ratchet relay completes the apparatus which controls the lighting circuit into which the invention is installed or with which it is used as a portable accessory. The system effects a saving of energy and adds greatly to the safety and security of home owners and to the insecurity of intruders. The invention is also a great aid to physically handicapped persons who are able to control lights within a building without the necessity of moving from place-to-place.
