Abstract
Abstract A moving contact arrangement, for a relay, for example, which allows for selective normally open and normally closed contact orientation with respect to fixed contacts by rotative movement between two opposite positions of a bridging bar carrying the moving contacts about an axis substantially parallel to and coextensive with a straight line connecting the moving contacts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
A movable contact arrangement for a switch device comprising: a moving contact carrier arranged for reciprocating movement with respect to a switch housing; said carrier supporting a moving contact bridging bar assembly for association with spaced, fixed contact surfaces located proximate either extremity of said bridging bar and supported by the housing; the contact surfaces of said bridging bar and the fixed contact surfaces extending substantially transverse to the direction of movement of said carrier; said assembly being rotatable in place and with respect to said carrier about an axis substantially parallel to and coextensive with a straight line connecting the contact surfaces of said bridging bar so as to relocate the bridging bar with respect to the fixed contact surfaces and thereby selectively provide a normally open or a normally closed contact orientation.
Claim 2
Dependent Claim
134 words
A movable contact arrangement for a switch device comprising: a moving contact carrier arranged for reciprocating movement with respect to a switch housing; said carrier supporting a moving contact bridging bar assembly for association with spaced, fixed contact surfaces located proximate either extremity of said bridging bar and supported by the housing; the contact surfaces of said bridging bar and the fixed contact surfaces extending substantially transverse to the direction of movement of said carrier; said assembly being rotatable in place and with respect to said carrier about an axis substantially parallel to and coextensive with a straight line connecting the contact surfaces of said bridging bar so as to relocate the bridging bar with respect to the fixed contact surfaces and thereby selectively provide a normally open or a normally closed contact orientation.
Claim 3
Dependent Claim
43 words
The arrangement of claim 1 wherein said bridging bar moving contact assembly includes a sleeve which is disposed in an opening contact carrier so as to allow for rotation of said assembly about the axis to thereby cause relocation of said bridging bar.
Claim 4
Dependent Claim
14 words
The arrangement of claim 2 wherein said sleeve and said opening are substantially cylindrical.
Claim 5
Dependent Claim
18 words
The arrangement of claim 3 wherein said sleeve includes means to be engaged for causing the rotAtion thereof.
Claim 6
Dependent Claim
35 words
The arrangement of claim 4 wherein said means comprises a tool engaging portion provided on an end face of said sleeve which is substantially parallel with the plane of movement of said moving contact carrier.
Claim 7
Dependent Claim
56 words
The arrangement of claim 4 wherein said means comprises a first gear portion associated with said sleeve, a second gear portion in driving engagement with said first gear and including an extension disposed so as to be engageable proximate a surface of said moving contact carrier which is substantially transverse to the plane of its movement.
Claim 8
Dependent Claim
52 words
The arrangement of claim 4 wherein said engagement means is operable from without said switch housing with said moving contact carrier remaining in place with respect to the housing and the fixed contact surfaces thereof to cause the contact surfaces of said bridging bar to be rotated about the fixed contact surfaces.
Claim 9
Dependent Claim
40 words
The arrangement of claim 2 wherein positioning means are provided to positively locate said bridging bar moving contact assembly in said moving contact carrier in the two extreme positions which allows for the normally open and normally closed contact orientations.
Claim 10
Dependent Claim
28 words
The arrangement of claim 8 wherein the positioning means are in the form of stops disposed between said moving contact carrier and said bridging bar moving contact assembly.
Claim 11
Dependent Claim
28 words
The arrangement of claim 8 wherein the positioning means are in the form of detents disposed between said moving contact carrier and said bridging bar moving contact assembly.
