Abstract

An electrical switching assembly. The electrical switching assembly includes an integral handle and rotor unit including an integral rotor portion and a handle portion. The rotor portion is configured to receive one or more conductors and is configured to be received in a line base. The integral handle and rotor unit includes the handle portion and the rotor portion in a one-piece assembly and the integral handle and rotor unit is molded as a single unit and formed from a single rigid insulating material.

First claim

What is claimed is:

1. An electrical switching assembly, comprising:
an integral handle and rotor unit including a rotor portion integral with a handle portion;
wherein the integral handle and rotor unit includes the handle portion and the rotor portion in a one-piece assembly, and
wherein the integral handle and rotor unit is molded as a single unit and formed from a single rigid insulating material;
the rotor portion configured to receive one or more conductors; and
the rotor portion configured to be received in a line base,
wherein a rotor of the rotor portion is arranged in the electrical switching assembly without a retaining mechanism that retains the rotor in predetermined positions or states including an ON state and an OFF state, and
wherein a handle of the handle portion is attached to the rotor in the electrical switching assembly without an attachment mechanism.

2. The electrical switching assembly of claim 1 , comprising:
one or more conductors extending radially through the rotor portion;
one or more orientation features on the rotor portion;
a line base comprising one or more openings configured to receive the one or more orientation features when the rotor portion is oriented in a predetermined position relative to the line base, wherein the rotor portion is configured to be rotatable about a central axis when the rotor portion is received within the one or more openings; and
one or more terminals in the line base, wherein the one or more conductors are configured to electrically contact the one or more terminals in response to rotation of the rotor portion.

3. The electrical switching assembly of claim 2 , wherein one or more orientation features includes one or more curved portions extending from the rotor portion.

4. The electrical switching assembly of claim 2 , wherein one or more orientation features includes a first flat surface.

5. The electrical switching assembly of claim 2 , wherein one or more orientation features includes a first flat surface and a second flat surface.

6. The electrical switching assembly of claim 5 , wherein the first flat surface is parallel to the second flat surface.

7. The electrical switching assembly of claim 2 , wherein the one or more orientation features includes one or more lobes extending from the rotor portion.

8. The electrical switching assembly of claim 7 , wherein one or more lobes extend further from the rotor portion than other elements of the rotor portion.

9. The electrical switching assembly of claim 2 , wherein the line base comprises one or more stops configured to contact the one or more conductors extending through the rotor portion in response to the integral handle and rotor unit rotating to a predetermined position.

10. The electrical switching assembly of claim 2 , wherein the one or more orientation features are configured to prevent the integral handle and rotor unit from being removed from the line base when the integral handle and rotor unit is in a position other than the predetermined position.

11. The electrical switching assembly of claim 2 , wherein the rotor portion includes an extension opposite the handle portion, wherein the line base includes a bore, and wherein the extension is received in the bore.

12. The electrical switching assembly of claim 1 , wherein the integral handle and rotor unit is made of an insulating material.

13. The electrical switching assembly of claim 1 , further comprising an enclosure including an interior and an opening between the interior and an exterior of the enclosure, wherein a line base is within the interior, wherein the rotor portion is received within the opening, and wherein the handle portion is exterior to the enclosure.

14. An electrical switching assembly comprising:
an enclosure including an interior and an enclosure opening extending between the interior and an exterior of the enclosure;
an integral handle and rotor unit including a rotor portion integral with a handle portion, the rotor portion being received in the enclosure opening;
one or more conductors extending radially through the rotor portion;
one or more orientation features on the rotor portion;
a line base within the interior of the enclosure including one or more line base openings configured to receive the one or more orientation features when the integral handle and rotor unit is oriented in a predetermined position relative to the line base, wherein the rotor portion is configured to be rotatable about a central axis when the rotor portion is received within the one or more line base openings; and
one or more terminals in the line base, wherein the one or more terminals are configured to contact the one or more conductors in response to rotation of the integral handle and rotor unit,
wherein a rotor of the rotor portion is arranged in the electrical switching assembly without a retaining mechanism that retains the rotor in predetermined positions or states including an ON state and an OFF state, and
wherein a handle of the handle portion is attached to the rotor in the electrical switching assembly without an attachment mechanism.

15. The electrical switching assembly of claim 14 , wherein the one or more orientation features includes one or more lobes extending from the rotor portion.

16. The electrical switching assembly of claim 15 , wherein one or more lobes extend further from the rotor portion than other elements of the rotor portion.

17. An electrical switching assembly, comprising:
an integral handle and rotor unit including a rotor portion integral with a handle portion;
one or more mounting features on the rotor portion; and
a line base configured to receive the one or more mounting features,
wherein the rotor portion configured to receive one or more conductors, and

wherein the rotor portion configured to be received in the line base,
wherein a rotor of the rotor portion is arranged in the electrical switching assembly without a retaining mechanism that retains the rotor in predetermined positions or states including an ON state and an OFF state, and
wherein a handle of the handle portion is attached to the rotor in the electrical switching assembly without an attachment mechanism.

18. The electrical switching assembly of claim 17 , comprising:
one or more conductors extending radially through the rotor portion;
one or more orientation features as the one or more mounting features on the rotor portion;
one or more openings in the line base that are configured to receive the one or more orientation features when the rotor portion is oriented in a predetermined position relative to the line base, wherein the rotor portion is configured to be rotatable about a central axis when the rotor portion is received within the one or more openings; and
one or more terminals in the line base, wherein the one or more conductors are configured to electrically contact the one or more terminals in response to rotation of the rotor portion.

19. The electrical switching assembly of claim 18 , wherein one or more orientation features includes one or more curved portions extending from the rotor portion.

20. The electrical switching assembly of claim 18 , wherein one or more orientation features includes a first flat surface.
