Abstract
Abstract An electric switch for connecting one or more of a plurality of leads on one side of an insulating substrate to a lead on the other side of the substrate. The switch includes a conductive contact member having a pin rotatably engaged in a hole in the substrate. The pin having a first end extending out of the first side of the substrate and having a head eccentrically connected thereto. The pin of the contact member is electrically connected to a lead on a second side of the substrate. Means are provided on the contact member for rotating the contact member head between the plurality of leads selectively to contact one or more of the leads on the first substrate side with the head to electrically connect the selected lead through the pin with the lead on the second substrate side.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
An improved electric switch including a substrate made of insulating material, said substrate having a first and a second side and being provided with at least one passage therethrough between said first and second side, a plurality of first conductive leads provided on said first side of said substrate, at least one second conductive lead provided on said second side of said substrate, said improvement comprising; at least one conductive contact member having a pin rotatably engaged in said substrate passage, said pin having a first end extending out of said first side of said substrate with a head eccentrically connected thereto, said pin being electrically connected to said second conductive lead, and said contact member including means for rotating said contact member head between said plurality of first conductive leads to selectively contact said contact member head with at least one of said first conductive leads, electrically connecting said selected first conductive lead with said second conductive lead through said contact member head and pin.
Claim 2
Dependent Claim
166 words
An improved electric switch including a substrate made of insulating material, said substrate having a first and a second side and being provided with at least one passage therethrough between said first and second side, a plurality of first conductive leads provided on said first side of said substrate, at least one second conductive lead provided on said second side of said substrate, said improvement comprising; at least one conductive contact member having a pin rotatably engaged in said substrate passage, said pin having a first end extending out of said first side of said substrate with a head eccentrically connected thereto, said pin being electrically connected to said second conductive lead, and said contact member including means for rotating said contact member head between said plurality of first conductive leads to selectively contact said contact member head with at least one of said first conductive leads, electrically connecting said selected first conductive lead with said second conductive lead through said contact member head and pin.
Claim 3
Dependent Claim
27 words
An improved electric switch as claimed in claim 1 in which said head of said contact member includes a substantially circular shape normal to the pin axis.
Claim 4
Dependent Claim
51 words
An improved electric switch as claimed in claim 1 in which the surface of said substrate formed by said passage in said substrate is metallized and said metallized surface is connected to said second conductive lead to produce an electrical contact between said contact member pin and said second conductive lead.
Claim 5
Dependent Claim
50 words
An improved electric switch as claimed in claim 1, in which there are a plurality of said contact members each engaged in a separate substrate passage, and a plurality of second conductive leads, with each of said contact members being connected to a different one of said second conductive leads.
Claim 6
Dependent Claim
44 words
An improved switch as claimed in claim 4 in which at least a pair of said first conductive leads are rectilinear and spaced parallel from each other, at least one passage and its contact member being located between said pair of first conductive leads.
Claim 7
Dependent Claim
48 words
An improved switch as claimed in claim 4 in which at least a pair of said first conductive leads are arranged in concentric arcs of a circle spaced from each other, at least one passage and its contact member being located between said pair of first conductive leads.
Claim 8
Dependent Claim
64 words
An improved switch as claimed in claim 4 in which one of said first conductive leads has a semi-circle shape, another of said first conductive leads having an enlarged end pad, said pad arranged in the center of and spaced from said semi-circle, at least one passage and its contact member being located between said pad and said semi-circle of said first conductive leads.
