Abstract
Abstract A rotary electrical switch comprises a stator supporting conventional stator contacts and having a central aperture to receive a rotor supporting at least one rotor blade of conventional design. The stator has an annular rib encircling said rotor and projecting axially from only one of its faces to axially locate said rotor blade. The rotor has a collar overlapping the opposite face of said stator and having a thickness substantially equal to the axial projection of said rib. Said collar and said rotor blade cooperate to clasp the central portion of said stator therebetween, and said collar adapted to support one or more additional rotor blades.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
In a rotary switch assembly comprising a one piece rotor having opposite sides rotatably mounted in a stator having opposite sides, a contact blade affixed to one side of said rotor, said stator having rib means axially elevated from one side thereof and disposed around said rotor, said contact blade lapping said rib means, said rotor having a collar lapping the opposite side of said stator.
Claim 2
Dependent Claim
66 words
In a rotary switch assembly comprising a one piece rotor having opposite sides rotatably mounted in a stator having opposite sides, a contact blade affixed to one side of said rotor, said stator having rib means axially elevated from one side thereof and disposed around said rotor, said contact blade lapping said rib means, said rotor having a collar lapping the opposite side of said stator.
Claim 3
Dependent Claim
70 words
The switch assembly of claim 1 wherein said contact blade projects radially outwardly from said rotor across and beyond said rib means, the portion of said blade projecting beyond said rib means spaced from said one side of said stator, and including stator contact means affixed to said stator, said contact means havIng a portion projecting into the space between said blade and said one side for wiping said blade.
Claim 4
Dependent Claim
15 words
The rotary switch of claim 1 including a second contact blade affixed to said collar.
Claim 5
Dependent Claim
64 words
The rotary switch of claim 3 in which said second contact blade projects outwardly from said collar in spaced relation to said opposite side of said stator, and including second stator contact means affixed to said stator, said second contact means having a portion projecting into the space between said second blade and said opposite side of said stator for wiping said second blade.
Claim 6
Dependent Claim
43 words
The rotary switch of claim 4 in which said collar supports said second rotor blade a distance from the opposite side of said stator which is substantially equal to the axial elevation of said rib means from said one side of said stator.
Claim 7
Dependent Claim
83 words
In a rotary switch assembly comprising a one piece rotor having opposite sides rotatably mounted in a stator having opposite sides, a feeder conductor affixed to one side of said rotor, feeder contact means affixed to a first side of said stator to wipe said conductor, said stator having rib means axially elevated from said first side and surrounding said rotor, said feeder conductor lapping said rib means, said rotor having a collar lapping the side of said stator opposite said first side.
Claim 8
Dependent Claim
83 words
In a rotary switch assembly comprising a one piece rotor having opposite sides rotatably mounted in a stator having opposite sides, a feeder conductor affixed to one side of said rotor, feeder contact means affixed to a first side of said stator to wipe said conductor, said stator having rib means axially elevated from said first side and surrounding said rotor, said feeder conductor lapping said rib means, said rotor having a collar lapping the side of said stator opposite said first side.
Claim 9
Dependent Claim
33 words
The rotary switch assembly of claim 6 wherein said collar has an axial thickness substantially equal in magnitude to the axial elevation of said rib means from said first side of said stator.
