Abstract

Abstract The invention is an improved electrical outlet of the kind normally found in household walls. These outlets usually have two slotted, prong holes, and a circular grounding hole. The improvement lies is providing the outlet with the ability to be set into one of three possible modes-normal, inoperable and "switched." In the normal mode the outlet functions in the normal way. In the inoperable mode the outlet provides no power at all. In the switched mode, the outlet may be operable or inoperable depending on the condition of an external switch located somewhere else in the home or building. The mode may be set by inserting a specially shaped key designed to fit into the prong holes of the outlet to thereby turn a special pivoting assembly located between the contact points and the back wall of the outlet assembly. The pivoting assembly may be pivoted in the manner of a lever resting in a fulcrum in one of three directions depending on which portion of the special key is depressed. Pivoting the assembly in a certain direction changes the power of the "hot" prong either grounding it, making it hot or connecting to the "switched" power supply.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 152 words
An electrical power outlet having three modes of operation comprising: outlet box having a neutral prong recess and a hot prong recess being, said neutral prong recess in connection with a neutral electrical power source, a hot power source having a hot terminal point near the back of said power outlet, a neutral power source having a neutral terminal point near the back of said outlet and a switched power source having a switched terminal point near the back of said power outlet, said hot prong recess having a hot prong contact point near the back of said recess, a means for contacting said hot prong contact point with one of each of said: hot terminal point, neutral terminal point and said switched terminal point, said switched power source in connection with an external switching means for supplying either no power or hot power depending on the condition of said external switch.
Claim 2
Dependent Claim 152 words
An electrical power outlet having three modes of operation comprising: outlet box having a neutral prong recess and a hot prong recess being, said neutral prong recess in connection with a neutral electrical power source, a hot power source having a hot terminal point near the back of said power outlet, a neutral power source having a neutral terminal point near the back of said outlet and a switched power source having a switched terminal point near the back of said power outlet, said hot prong recess having a hot prong contact point near the back of said recess, a means for contacting said hot prong contact point with one of each of said: hot terminal point, neutral terminal point and said switched terminal point, said switched power source in connection with an external switching means for supplying either no power or hot power depending on the condition of said external switch.
Claim 3
Dependent Claim 106 words
The apparatus of claim 1 wherein said enabling means comprises a triangular shaped disk, said disk located between said hot prong contact point and said back wall of said outlet, said disk fixed for pivoting movement in one of three directions, said disk having a peripheral contacting strip on each of said sides of said triangular shape, said contacting strips in close proximity to said hot terminal point, said neutral terminal point and said switched terminal point, so that said hot prong contact point may be connected to each of said hot power, no power and switched power supplies through the pivoting movement of said disk.
