Abstract

An apparatus and system disconnects electrical power from an electrical power outlet. Specifically, the apparatus and system disconnects electrical power, such as AC power, from an electrical receptacle and a timer when the timer has expired. More specifically, the apparatus and system for disconnecting electrical power has a plurality of switches to engage a timer circuit. A first switch either engages the timer circuit or bypasses the timer circuit. Upon engaging the timer circuit, a second switch is engaged to supply power to the timer circuit for the duration of a timer. A third switch allows a user to select various timer values to set the duration of the timer. One or more indicators informs a user whether the bypass circuit is engaged or whether the timer circuit is engaged.

Claims

1. An electrical timer apparatus comprising:

a connector to engage AC power from an AC power source;

a female electrical receptacle for engaging a male electrical plug;

a timer circuit comprising a timer selector for selecting a timed interval and a momentary switch for completing the timer circuit, wherein the timer circuit provides electrical power to the female electrical receptacle and to the timer circuit when the momentary switch is engaged and further wherein the timer circuit disconnects electrical power from the female electrical receptacle and the timer circuit when the timed interval elapses;

a bypass circuit for providing electrical power to the female electrical receptacle when the bypass circuit is completed with the AC power; and

a switch to select either the timer circuit or the bypass circuit.

2. The electrical timer apparatus of claim 1 wherein the timer circuit comprises an electrical timer wherein the electrical timer provides the selectable timed interval.

3. The electrical timer apparatus of claim 1 wherein the timer circuit comprises a relay for allowing electrical power to flow to the female electrical receptacle and to the timer circuit when the timer circuit is selected via the switch, the timed interval is selected via the timer selector, and the momentary switch is engaged completing the timer circuit and further wherein the relay disconnects the electrical power from the female electrical receptacle and the timer circuit when the timed interval elapses.

4. The electrical timer apparatus of claim 1 wherein the timer circuit comprises an electrical timer wherein the electrical timer provides the selectable timed interval and further wherein the timer circuit comprises a relay for allowing electrical power to flow to the female electrical receptacle during the timed interval and further wherein the relay disconnects the electrical power from the female electrical receptacle and the timer circuit when the timer elapses.

5. The electrical timer apparatus of claim 1 wherein the timer selector comprises a plurality of selectable timed intervals.

6. The electrical timer apparatus of claim 1 wherein the connector to engage AC power from an AC power source is a male electrical plug to engage a female electrical receptacle.

7. The electrical timer apparatus of claim 1 further comprising a remote control apparatus wherein the switch, timer selector and momentary switch are operational remotely from the electrical timer switch apparatus.

8. The electrical timer apparatus of claim 1 further comprising:

an indicator showing when AC power flows to the female electrical receptacle.

9. The electrical timer apparatus of claim 1 further comprising:

an indicator showing when the bypass circuit is selected via the switch.

10. The electrical timer apparatus of claim 1 further comprising:

a DC power supply for powering the electrical timer circuit when the timer circuit is selected via the switch.

11. A system for disconnecting electrical power from an AC power source to a device requiring AC power for operation;

the system comprising;

an AC power source;

a device requiring AC power;

an electrical timer apparatus comprising;

a connector to engage AC power from an AC power source;

a female electrical receptacle for engaging a male electrical plug;

a timer circuit comprising a timer selector for selecting a timed interval and a momentary switch for completing the timer circuit, wherein the timer circuit provides electrical power to the female electrical receptacle and to the timer circuit when the momentary switch is engaged and further wherein the timer circuit disconnects electrical power from the female electrical receptacle and the timer circuit when the timed interval elapses;

a bypass circuit for providing electrical power to the female electrical receptacle when the bypass circuit is completed with the AC power; and

a switch to select either the timer circuit or the bypass circuit,

wherein the device is plugged into the female electrical receptacle of the electrical timer apparatus and the electrical timer apparatus is connected to the AC power source.

12. The system of claim 11 wherein the timer circuit comprises an electrical timer wherein the electrical timer provides the selectable timed interval.

13. The system of claim 11 wherein the timer circuit comprises a relay for allowing electrical power to flow to the female electrical receptacle and to the timer circuit when the timer circuit is selected via the switch, the timed interval is selected via the timer selector, and the momentary switch is engaged completing the timer circuit and further wherein the relay disconnects the electrical power from the female electrical receptacle and the timer circuit when the timed interval elapses.

14. The system of claim 11 wherein the timer circuit comprises an electrical timer wherein the electrical timer provides the selectable timed interval and further wherein the timer circuit comprises a relay for allowing electrical power to flow to the female electrical receptacle during the timed interval and further wherein the relay disconnects the electrical power from the female electrical receptacle and the timer circuit when the timer elapses.

15. The system of claim 11 wherein the timer selector comprises a plurality of selectable timed intervals.

16. The system of claim 11 wherein the connector to engage AC power from an AC power source is a male electrical plug to engage a female electrical receptacle.

17. The system of claim 11 further comprising a remote control apparatus wherein the switch, timer selector and momentary switch are operational remotely from the electrical timer apparatus.

18. The system of claim 11 further comprising:

an indicator showing when AC power flows to the female electrical receptacle.

19. The system of claim 11 further comprising:

an indicator showing when the bypass circuit is selected via the switch.
