Abstract
Abstract A switch mechanism is disclosed as including a body member containing the switching elements for an electrical circuit and a rotary external actuator for producing corresponding rotary motion to the switching elements for placing the switch mechanism into its controlling conditions. The actuator is held in a restrained position upon the body member and also resiliently biased into a controlling condition by a single element, a coil spring.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
A switching mechanism for providing an electrical connection between two conductors associated therewith comprising a body member having a first contact element mounted thereon and connected to one of the conductors, and a second contact element mounted thereon spaced from said first contact element and being connected to the other conductor, an actuator member rotatably mounted on said body member and having a switching element connected thereto and rotatably movable therewith, said actuator member being movable to a first position wherein said movable switching element is out of electrical contact with said contact elements and to a second position wherein said movable switching element is in electrical contact with said contact elements, and a spring member associated with said actuator and arranged to resiliently bias the same to one of said positions, said body member and said actuator each having means for holding a portion of said spring member, respectively, for retaining said actuator on said body member.
Claim 2
Dependent Claim
158 words
A switching mechanism for providing an electrical connection between two conductors associated therewith comprising a body member having a first contact element mounted thereon and connected to one of the conductors, and a second contact element mounted thereon spaced from said first contact element and being connected to the other conductor, an actuator member rotatably mounted on said body member and having a switching element connected thereto and rotatably movable therewith, said actuator member being movable to a first position wherein said movable switching element is out of electrical contact with said contact elements and to a second position wherein said movable switching element is in electrical contact with said contact elements, and a spring member associated with said actuator and arranged to resiliently bias the same to one of said positions, said body member and said actuator each having means for holding a portion of said spring member, respectively, for retaining said actuator on said body member.
Claim 3
Dependent Claim
37 words
The switching mechanism of claim 1 wherein said spring member is a coil spring having one end retained in said holding means of said body member and another end retained in said holding means of said actuator.
Claim 4
Dependent Claim
21 words
The switching mechanism of claim 2 wherein said contact elements are planar in shape and lie in approximately the same plane.
Claim 5
Dependent Claim
25 words

Claim 6
Dependent Claim
156 words
A switching mechanism for providing an electrical connection between two conductors associated therewith comprising a body member having a first fixed contact plate mounted thereon and connected to one of the conductors, and a second fixed contact plate mounted thereon spaced from said first contact plate and being connected to the other conductor, an actuator member rotatably mounted on said body member and having a switching element connected thereto and rotatably movable therewith, said actuator member being movable to a first position wherein said switching element is out of electrical contact with said contact plates and to a second position wherein said element is in electrical contact with said plates, and a spring member associated with said actuator and arranged to resiliently bias the same to one of said positions, said body member and said actuator each having means for holding a portion of said spring member, respectively, for retaining said actuator on said body member.
Claim 7
Dependent Claim
156 words
A switching mechanism for providing an electrical connection between two conductors associated therewith comprising a body member having a first fixed contact plate mounted thereon and connected to one of the conductors, and a second fixed contact plate mounted thereon spaced from said first contact plate and being connected to the other conductor, an actuator member rotatably mounted on said body member and having a switching element connected thereto and rotatably movable therewith, said actuator member being movable to a first position wherein said switching element is out of electrical contact with said contact plates and to a second position wherein said element is in electrical contact with said plates, and a spring member associated with said actuator and arranged to resiliently bias the same to one of said positions, said body member and said actuator each having means for holding a portion of said spring member, respectively, for retaining said actuator on said body member.
Claim 8
Dependent Claim
37 words
