Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
An illuminating switch apparatus comprising: a case 10; a light source 29 disposed on said case 10; a plurality of switches 12, 13 disposed on said case 10 and spaced from said light source 29, each of said plurality of switches 12, 13 comprising a bearing portion 15 and switch operating members 23, 31 pivotally disposed on said bearing portions 15 about an axis, said switch operating members 23, 31 defining light conducting paths 23b; and a light conducting body 25 disposed on said case 10 comprising a plurality of arms extending from a point adjacent said light source 29 to said switch operating members 23, 31, said arms having an upper surface projecting portion 27 and at least one reflecting surface 25a, 26 such that light from said light source 29 is reflected by said at least one reflecting surface 25a, 26 and through said upper surface projecting portion 27 such that said light is directed through said light conduction paths 23b.
Claim 2
Dependent Claim
163 words
An illuminating switch apparatus comprising: a case 10; a light source 29 disposed on said case 10; a plurality of switches 12, 13 disposed on said case 10 and spaced from said light source 29, each of said plurality of switches 12, 13 comprising a bearing portion 15 and switch operating members 23, 31 pivotally disposed on said bearing portions 15 about an axis, said switch operating members 23, 31 defining light conducting paths 23b; and a light conducting body 25 disposed on said case 10 comprising a plurality of arms extending from a point adjacent said light source 29 to said switch operating members 23, 31, said arms having an upper surface projecting portion 27 and at least one reflecting surface 25a, 26 such that light from said light source 29 is reflected by said at least one reflecting surface 25a, 26 and through said upper surface projecting portion 27 such that said light is directed through said light conduction paths 23b.
Claim 3
Dependent Claim
55 words
An apparatus of claim 1 wherein said each of said switch operating members 23, 31 comprises an elongated structure disposed radially from said axis, said light conduction paths 23b extending through said elongated structure from a first point adjacent said bearing portions 15 to a second point at an extreme end of said elongated structure.
Claim 4
Dependent Claim
53 words
An apparatus of claim 2 wherein each of said plurality of switches 12, 13 further comprise a pair of projecting portions 23a spaced to define a gap therebetween, said gap being disposed adjacent said light conducting paths 23B such that said upper surface projecting portion 27 is disposed between said projecting portions 23a.
Claim 5
Dependent Claim
22 words
An apparatus of claim 1 wherein the number of switches 12, 13 illuminated by said light source 29 is three or more.
