Abstract
Abstract A switching matrix includes a settable matrix adapted for insertion between input and output contact boards. Sliders of insulative material, carrying knife-edged cross contacts, are secured to separate guides in the settable matrix. The cross contacts are adapted to provide an electrical connection between two conductive paths, one associated with the input contact board and one associated with the output contact board.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
45 words
A switching matrix comprising an input contact board and an output contact board, said boards each having a plurality of conductive paths, means for securing said boards in spaced relation, and a settable matrix having means for infinitely varying the setting between said contact boards.
Claim 2
Dependent Claim
45 words
A switching matrix comprising an input contact board and an output contact board, said boards each having a plurality of conductive paths, means for securing said boards in spaced relation, and a settable matrix having means for infinitely varying the setting between said contact boards.
Claim 3
Dependent Claim
65 words
A switching matrix comprising an input contact board and an output contact board, said boards each having a plurality of conductive paths, means for securing said boards in spaced relation, and a settable matrix adapted for insertion between said input and output boards, said settable matrix comprising a plurality of guides and a plurality of slides, each of which is secured to a separate guide.
Claim 4
Dependent Claim
65 words
A switching matrix comprising an input contact board and an output contact board, said boards each having a plurality of conductive paths, means for securing said boards in spaced relation, and a settable matrix adapted for insertion between said input and output boards, said settable matrix comprising a plurality of guides and a plurality of slides, each of which is secured to a separate guide.
Claim 5
Dependent Claim
25 words
The combination set forth in claim 2 in which each of said slides comprises an insulative block and a cross-contact secured to said insulative block.
Claim 6
Dependent Claim
22 words
The combination set forth in claim 3 in which said input contact board and said output contact board are printed circuit boards.
Claim 7
Dependent Claim
46 words
The combination set forth in claim 3 in which said conductive paths are in a straight line, and said plurality of conductive paths associated with said input contact boards are substantially perpendicular with respect to said pluraliTy of conductive paths associated with said output contact board.
Claim 8
Dependent Claim
37 words
The combination set forth in claim 3 in which each of said cross-contacts is adapted to engage simultaneously one conductive path associated with said input contact board and one conductive path associated with said output contact board.
Claim 9
Dependent Claim
37 words
The combination set forth in claim 6 in which each cross-contact comprises two knife edges, one knife edge being engaged with one input conductive path and the other knife edge being engaged with one output conductive path.
Claim 10
Dependent Claim
35 words
The combination set forth in claim 6 in which each of said cross-contact comprises conductive material bent so as to give spring action to those parts of said cross-contact adapted to engage said conductive paths.
Claim 11
Dependent Claim
65 words
The combination set forth in claim 6 in which each of said cross-contacts comprises conductive material bent so as to give spring action to those parts of said cross-contact adapted to engage said conductive paths and two knife edges on said conductive material, one knife edge being engaged with one input conductive path and the other knife edge being engaged with one output conductive path.
