Abstract

Electrical devices, such as electrical switch devices, include a printed circuit board (PCB) that includes a communication circuit configured to communicate with a remote device and a processing circuit, a magnet, and a magnetic sensor configured to sense a magnetic field emanating from the magnet, where rotation of the handle between a first position and a second position causes rotational motion of at least one of the magnet and the magnetic sensor, the rotational motion repositioning the magnet and the magnetic sensor relative to each other, and where the magnetic sensor is configured to sense the repositioning and output a signal to the processing circuit indicative of a position of the handle.

First claim

What is claimed is:

1 . An electrical switch device for supplying power to a load, the electrical switch device comprising:
a printed circuit board (PCB), the PCB comprising a communication circuit configured to communicate with a remote device and a processing circuit; a handle configured to rotate between a first position and a second position; a load switch arranged and configured to open and close to selectively supply power to the load; a magnet; and a magnetic sensor configured to sense a magnetic field emanating from the magnet; wherein rotation of the handle between the first position and the second position causes rotational motion of at least one of the magnet and the magnetic sensor, the rotational motion repositioning the magnet and the magnetic sensor relative to each other, and wherein the magnetic sensor is configured to sense the repositioning and output a signal to the processing circuit indicative of a position of the handle.

2 . The electrical switch device of claim 1 , wherein rotation of the handle between the first position and the second position causes the load switch to open and close.

3 . The electrical switch device of claim 1 , further comprising a component configured to rotate based on rotation of the handle between the first position and the second position, wherein the magnet is coupled to the component.

4 . The electrical switch device of claim 3 , wherein rotation of the handle between the first position and the second position causes rotational motion of the magnet to move the magnet closer to, or farther from, the magnetic sensor.

5 . The electrical switch device of claim 3 , wherein the component is a handle shaft, and wherein the magnet is disposed at least partially embedded in the handle shaft.

6 . The electrical switch device of claim 1 , further comprising a stop plate disposed between the magnet and the magnetic sensor, wherein the stop plate comprises an opening, and wherein when the handle is positioned in the first position, the magnet is closer to the opening of the stop plate than when the handle is positioned in the second position.

7 . The electrical switch device of claim 6 , wherein based on the handle being in the first position, the magnet is in one position that is at least partially aligned with the opening of the stop plate, and wherein based on the handle being in the second position the magnet is in another position that is out-of-alignment with the opening of the stop plate.

8 . The electrical switch device of claim 7 , wherein the magnetic sensor is configured to sense the magnetic field emanating from the magnet in the one position based on the handle being in the first position, wherein the intensity of the magnetic field emanating from the magnet as sensed by the magnetic sensor is greater when the handle is in the first position and the magnet is in the one position as compared to when the handle is in the second position and the magnet is in the another position.

9 . The electrical switch device of claim 8 , wherein the one position, in which the magnet is at least partially aligned with the opening of the stop plate, corresponds to an OFF position in which the load switch is open, and wherein the another position, in which the magnet is out-of-alignment with the opening of the stop plate, corresponds to an ON position in which the load switch is closed to provide the power to the load.

10 . The electrical switch device of claim 6 , wherein the stop plate comprises material with a shielding property that shields the magnetic field sensor from the magnetic field emanating from the magnet when the handle is positioned in the second position, and wherein the opening of the stop plate is positioned and configured such that when the handle is positioned in the first position, the magnetic field sensor senses the magnet field emanating from the magnet passes through the opening in the stop plate.

11 . The electrical switch device of claim 1 , wherein the electrical switch device comprises a stacked board arrangement in which the magnet, the magnetic sensor, and the PCB are provided in a stacked configuration coupled together and at least partially enclosed in a cover of the electrical switch device.

12 . The electrical switch device of claim 1 , wherein the load switch is configured to accept a plurality of input power phase conductors, and wherein the electrical switch device further comprises a current sensor configured to sense a respective level of current through each phase conductor of the plurality of input power phase conductors and communicate, via a PCB of the current sensor, the sensed respective level of current through each phase conductor to another component of the electrical switch device.

13 . The electrical switch device of claim 12 , further comprising a clip coupled to the current sensor, the clip configured to maintain one or more conductors proximate the current sensor.

14 . An electrical device comprising:
a cover subassembly configured for operatively coupling with a handle, the cover subassembly comprising:
a printed circuit board (PCB), the PCB comprising a communication circuit configured to communicate with a remote device and a processing circuit;
a magnet; and
a magnetic sensor configured to sense a magnetic field emanating from the magnet;
wherein the cover subassembly is configured such that rotation of the handle between the first position and the second position causes rotational motion of at least one of the magnet and the magnetic sensor, the rotational motion repositioning the magnet and the magnetic sensor relative to each other, and wherein the magnetic sensor is configured to sense the repositioning and output a signal to the processing circuit indicative of a position of the handle.

15 . The electrical device of claim 14 , wherein the cover subassembly further comprises a component configured to rotate based on rotation of the handle between the first position and the second position, wherein the magnet is coupled to the component.

16 . The electrical device of claim 15 , wherein the cover subassembly is configured such that rotation of the handle between the first position and the second position causes rotational motion of the magnet to move the magnet closer to, or farther from, the magnetic sensor.

17 . The electrical device of claim 15 , wherein the component is a handle shaft, and wherein the magnet is disposed at least partially embedded in the handle shaft.

18 . The electrical device of claim 14 , wherein the cover subassembly further comprises a stop plate disposed between the magnet and the magnetic sensor, wherein the stop plate comprises an opening, and wherein the cover subassembly is configured such that when the handle is positioned in the first position, the magnet is closer to the opening of the stop plate than when the handle is positioned in the second position.

19 . The electrical device of claim 18 , wherein the cover subassembly is configured such that the magnet is in one position that is at least partially aligned with the opening of the stop plate based on the handle being in the first position, and the magnet is in another position that is out-of-alignment with the opening of the stop plate based on the handle being of the second position.

20 . The electrical device of claim 19 , wherein the magnetic sensor is configured to sense the magnetic field emanating from the magnet in the one position based on the handle being in the first position, wherein the in
