Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A rotary switch comprising: a recessed body with resilient fixed contacts located in the periphery of the recess; a cover plate with an enlarged opening therein covering the recess; means for holding the cover plate in place on the body; a set of rotary contacts located in the recess; a single piece integrally formed rotating carrier member including a rounded end portion having means around the circumference thereof for receipt of the rotary contacts, an enlarged shaft portion extending from the rounded end portion, journaled in the cover plate opening, and a handle portion axially extending from the shaft portion, the handle portion having a dimension substantially equal to or less than the diameter of the enlarged shaft portion whereby when assembled or disassembled the handle portion can be passed through the cover plate opening.
Claim 2
Dependent Claim
135 words
A rotary switch comprising: a recessed body with resilient fixed contacts located in the periphery of the recess; a cover plate with an enlarged opening therein covering the recess; means for holding the cover plate in place on the body; a set of rotary contacts located in the recess; a single piece integrally formed rotating carrier member including a rounded end portion having means around the circumference thereof for receipt of the rotary contacts, an enlarged shaft portion extending from the rounded end portion, journaled in the cover plate opening, and a handle portion axially extending from the shaft portion, the handle portion having a dimension substantially equal to or less than the diameter of the enlarged shaft portion whereby when assembled or disassembled the handle portion can be passed through the cover plate opening.
Claim 3
Dependent Claim
26 words
A rotary switch as set forth in claim 1, wherein the diameter of the shaft portion is less than the diameter of the rounded end portion.
Claim 4
Dependent Claim
59 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein for receipt of the carrier member, a circumferential groove extending partially around the Periphery of the carrier member, and a stationary tab means extending into said circumferential groove limiting the angular rotary movement of the carrier member.
Claim 5
Dependent Claim
69 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein for receipt of the carrier member, a circumferential groove extending partially around the periphery of the rounded end portion of the carrier and a tab means extending inwardly from the opening in the insulating plate into said groove limiting the angular rotary movement of the carrier member.
Claim 6
Dependent Claim
85 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein for receipt of the carrier member, a circumferential groove extending partially around the periphery of the rounded end portion of the carrier and a tab means extending inwardly from the opening in the insulating plate into said groove limiting the angular rotary movement of the carrier member, the diameter of the shaft portion being less than the diameter of the rounded end portion.
Claim 7
Dependent Claim
88 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein to journally receive the rounded end portion of the carrier, a circumferential groove extending partially around a portion of the rounded end portion of the carrier, and a tab means extending inwardly from the opening in the insulating plate into said groove limiting the angular movement of the carrier member, the diameter of the shaft portion being less than the diameter of the rounded end portion.
Claim 8
Dependent Claim
29 words
A rotary switch as set forth in claim 1, wherein the handle portion dimension is the width which is substantially equal to the diameter of the enlarged shaft position.
Claim 9
Dependent Claim
38 words
A rotary switch as set forth in claim 1, wherein the handle portion extends along a diameter line of the enlarged shaft a diameter distance whereby the handle portion freely slides through the opening in the cover plate.
Claim 10
Dependent Claim
108 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein to journally receive the rounded end portion of the carrier, a circumferential groove extending partially around a portion of the rounded end portion of the carrier, and a tab means extending inwardly from the opening in the insulating plate into said groove limiting the angular movement of the carrier member, the diameter of the shaft portion being less than the diameter of the rounded end portion, and the handle portion dimension being the width which is substantially equal to the diameter of the enlarged shaft portion.
Claim 11
Dependent Claim
78 words
A rotary switch as set forth in claim 1, including an insulating plate positioned under the cover plate with an opening therein for receipt of the carrier member, a circumferential groove extending partially around the periphery of the carrier member, and a stationary tab means extending into said circumferential groove limiting the angular rotary movement of the carrier member, the handle portion dimension being the width which is substantially equal to the diameter of the enlarged shaft portion.
