Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
194 words
A remote control apparatus for home lighting and the like comprising a portable radio signal transmitter adapted for manual operation at a remote point, a coacting radio signal receiver adapted for placement in a home or the like having contacts which close upon reception of a radio signal by the receiver, a step down transformer having a primary coil adapted for coupling to a source of alternating house current and a secondary coil having first and second terminals, one secondary coil terminal coupled with one contact of said receiver, a ratchet relay having first and second terminals, a normally open contact, a normally closed contact and a common contact, one terminal of the ratchet relay being coupled with the second terminal of said transformer secondary coil and the secondary terminal of the ratchet relay being coupled with a second terminal of said receiver, a house lighting circuit including a manual light switch having a pair of contacts which are electrically coupled to said normally open and normally closed ratchet relay contacts, and said house lighting circuit having a conductor coupled with said common contact of the ratchet relay, said common contact having power thereon.
