Switched receptacle device with LED indication
View Patent ↗A switched receptacle device with led indication made up of a standard two-outlet receptacle that has two respective hot terminals and two respective neutral terminals, a resistor electrically connected to a first outlet neutral terminal; an LED having a first lead and a second lead electrically connected by the LED first lead in series with the resistor, and the second lead electrically connected to a first outlet hot terminal; and a rectifier diode electrically connected in parallel across the LED first lead and second lead, whereby the LED is activated whenever a switch has energized a hot terminal.
1. A switched receptacle system with a light emitting diode (LED) indication comprising:
a wall switch constructed and arranged to be embedded into a wall; and
a residential grade receptacle device disposed in electrical communication with the wall switch, the device having:
a top receptacle portion comprising a first two-prong outlet and a second two-prong outlet;
a bottom receptacle portion comprising:
a first outlet hot terminal electrically connected to the first outlet, the first outlet hot terminal constructed and arranged to (i) receive power from a power source when the wall switch is turned on and (ii) become non-energized when the wall switch is turned off;
a first outlet neutral terminal electrically connected to the first outlet;
a second outlet hot terminal electrically connected to the second outlet, the second outlet hot terminal constructed and arranged to receive power from the power source regardless of whether the wall switch is turned on or is turned off; and
a second outlet neutral terminal electrically connected to the second outlet;
a resistor electrically connected to the first outlet neutral terminal;
an LED comprising a first lead electrically connected in series with the resistor, and a second lead electrically connected to the first outlet hot terminal; and
a rectifier diode electrically connected in parallel across the LED first lead and second lead, whereby the LED (i) is activated whenever the wall switch is turned on indicating that the first outlet hot terminal is receiving power from the power source, and (ii) is deactivated whenever the wall switch is turned off indicating that the first outlet hot terminal is non-energized.
2. The system of claim 1 , wherein the resistor is a nominal 33 k-ohm resistor.
3. The system of claim 2 , wherein the resistor is a 33 kΩ, ½ W, 5% tolerance resistor.
4. The system of claim 1 , wherein the LED is a 30 mA LED.
5. The system of claim 4 , wherein the LED is a 5 mm, 2.1 V 30 mA LED.
6. The system of claim 1 , wherein the first outlet and second outlet are co-planar with the top receptacle portion, the top receptacle portion further comprising a through hole for receiving the LED perpendicular to the plane of first outlet and second outlet.
7. The system of claim 6 , the bottom receptacle portion further comprising a recess for receiving the LED and the rectifier diode within.
