The circuit includes a first connecting pole configured for placement within a first wire reception hole of the duplex receptacle electrical outlet. The first wire reception hole is in electrical contact with a hot wire connection of the duplex receptacle electrical outlet. A second connecting pole is configured for placement within a second wire reception hole of the duplex receptacle electrical outlet. The second wire reception hole is in electrical contact with a neutral wire connection of the duplex receptacle electrical outlet. A control circuit is connected to the first connecting pole and the second connecting pole. ## Claims ### Claim 1 A circuit board for use with a duplex receptacle electrical outlet, the duplex receptacle electrical outlet having a first power receptacle and a second power receptacle, the circuit board comprising: a first connecting pole configured for placement within a first wire reception hole of the duplex receptacle electrical outlet, the first wire reception hole being in electrical contact with the first power receptacle of the duplex receptacle electrical outlet, wherein the first wire reception hole is on a different side of the duplex receptacle electrical outlet than is the first power receptacle; a second connecting pole configured for placement within a second wire reception hole of the duplex receptacle electrical outlet, the second wire reception hole being in electrical contact with the second power receptacle of the duplex receptacle electrical outlet, wherein the second wire reception hole is on a different side of the duplex receptacle electrical outlet than is the second power receptacle; a relay connected between the first connecting pole and the second connecting pole, wherein the relay, in response to a control signal, electrically connects or disconnects the first connecting pole and the second connecting pole; a control circuit that generates the control signal; and, a receiver, connected to the control circuit that receives communication for the control circuit; wherein when circuit board is mounted on the duplex receptacle electrical outlet, the circuit does not cover the first power receptacle or the second power receptacle. ### Claim 2 (depends on 1) A circuit board as in claim 1, additionally comprising: a status light, controlled by the control circuit, that indicates whether the duplex receptacle electrical outlet is functional. ### Claim 3 A circuit board for use with a duplex receptacle electrical outlet, the duplex receptacle electrical outlet having a first power receptacle and a second power receptacle, the circuit board comprising: a first connecting pole configured for placement within a first wire reception hole of the duplex receptacle electrical outlet, the first wire reception hole being in electrical contact with a hot wire connection of the duplex receptacle electrical outlet, wherein the first wire reception hole is on a different side of the duplex receptacle electrical outlet than is the first power receptacle; a second connecting pole configured for placement within a second wire reception hole of the duplex receptacle electrical outlet, the second wire reception hole being in electrical contact with a neutral wire connection of the duplex receptacle electrical outlet, wherein the second wire reception hole is on a different side of the duplex receptacle electrical outlet than is the first power receptacle; a control circuit connected to the first connecting pole and the second connecting pole; and, a status light, controlled by the control circuit, that indicates whether the duplex receptacle electrical outlet is functional; wherein the circuit board is adapted to be mounted on the duplex receptacle electrical outlet without covering the first power receptacle or the second power receptacle. ### Claim 4 (depends on 3) A circuit board as in claim 3, additionally comprising: a third connecting pole configured for placement within a third wire reception hole of the duplex receptacle electrical outlet, the second wire reception hole being in electrical contact with a second hot wire connection of the duplex receptacle electrical outlet; and, a relay connected between the first connecting pole and the third connecting pole, wherein the relay, in response to a control signal from the control circuit, electrically connects or disconnects the first connecting pole and the third connecting pole. ### Claim 5 (depends on 4) A circuit board as in claim 4, additionally comprising: a wireless receiver, connected to the control circuit that receives wireless communication for the control circuit. ### Claim 6 (depends on 3) A circuit board as in claim 3, additionally comprising: a wireless receiver, connected to the control circuit that receives wireless communication for the control circuit. ### Claim 7 A circuit board for use with a duplex receptacle electrical outlet, the duplex receptacle electrical outlet having a first power receptacle and a second power receptacle, the circuit board comprising: a first connecting pole configured for placement within a first wire reception hole of the duplex receptacle electrical outlet, the first wire reception hole being in electrical contact with a hot wire connection of the duplex receptacle electrical outlet, wherein the first wire reception hole is on a different side of the duplex receptacle electrical outlet than is the first power receptacle; a second connecting pole configured for placement within a second wire reception hole of the duplex receptacle electrical outlet, the second wire reception hole being in electrical contact with a neutral wire connection of the duplex receptacle electrical outlet, wherein the second wire reception hole is on a different side of the duplex receptacle electrical outlet than is the first power receptacle; a control circuit connected to the first connecting pole and the second connecting pole; and, a wireless receiver, connected to the control circuit that receives wireless communication for the control circuit; wherein the circuit board is adapted to be mounted on the duplex receptacle electrical outlet without covering the first power receptacle or the second power receptacle. ### Claim 8 (depends on 7) A circuit board as in claim 7, additionally comprising: a third connecting pole configured for placement within a third wire reception hole of the duplex receptacle electrical outlet, the second wire reception hole being in electrical contact with a second hot wire connection of the duplex receptacle electrical outlet; and, a relay connected between the first connecting pole and the third connecting pole, wherein the relay, in response to a control signal from the control circuit, electrically connects or disconnects the first connecting pole and the third connecting pole. ### Claim 9 (depends on 8) A circuit board as in claim 8, additionally comprising: a status light, controlled by the control circuit, that indicates whether the duplex receptacle electrical outlet is functional. ### Claim 10 (depends on 7) A circuit board as in claim 7, additionally comprising: a status light, controlled by the control circuit, that indicates whether the duplex receptacle electrical outlet is functional.
