Abstract
Abstract A linear switch assembly comprises a planar plate secured to the inner wall of a housing for a light source. A carriage member has a first slot positioned within the edge of the plate member and a second shorter slot on a top adjacent surface. The plate has an extending rigid rod positioned within the second slot to allow the carriage to move along the plate member in a linear direction. Associated with the carriage member are first and second lamp assemblies each having an associated actuatable switch. As the carriage is moved the rod coacts with an operating lever associated with each switch to actuate the switch when the associated lamp assembly is moved into a proper position whereby power is supplied to each lamp assembly only when at the proper operating position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
224 words
A switch assembly for selecting one of a first and second lamp assembly, comprising: (a) a carriage member having a first slot in one sidewall thereof, with said slot directed from the top to the bottom surface of said member, said member having a second slot in an adjacent sidewall with said second slot parallel to said first slot and of a shorter length, (b) a planar rigid plate member with one edge of said member positioned within said first slot to allow said carriage member to move along said planar member as guided by said edge, (c) an extending rod secured to said planar plate member and extending through said second slot for defining a linear path of motion for said carriage member, (d) first and second actuatable switching means positioned on said carriage member with said first switching means located near one end of said second slot and said second switching means located near the opposite end of said second slot, with said switching means adapted to be actuated by said rod when said carriage member is moved along said planar member, (e) first and second lamp assemblies each associated with a separate one of said switches whereby when said carriage is moved along said planar member a separate one of said switching means is actuated to illuminate said associated lamp assembly.
Claim 2
Dependent Claim
224 words
A switch assembly for selecting one of a first and second lamp assembly, comprising: (a) a carriage member having a first slot in one sidewall thereof, with said slot directed from the top to the bottom surface of said member, said member having a second slot in an adjacent sidewall with said second slot parallel to said first slot and of a shorter length, (b) a planar rigid plate member with one edge of said member positioned within said first slot to allow said carriage member to move along said planar member as guided by said edge, (c) an extending rod secured to said planar plate member and extending through said second slot for defining a linear path of motion for said carriage member, (d) first and second actuatable switching means positioned on said carriage member with said first switching means located near one end of said second slot and said second switching means located near the opposite end of said second slot, with said switching means adapted to be actuated by said rod when said carriage member is moved along said planar member, (e) first and second lamp assemblies each associated with a separate one of said switches whereby when said carriage is moved along said planar member a separate one of said switching means is actuated to illuminate said associated lamp assembly.
Claim 3
Dependent Claim
24 words
The switch assembly according to claim 1, further including an extending arm coupled to said carriage assembly for moving the same along said edge.
Claim 4
Dependent Claim
58 words
The switch assembly according to claim 1, further including top and bottom detent coacting means located on said carriage assembly for defining a first and second position indicative of actuating said first and second lamp assemblies, with detent means positioned on said planar member indicative of said first and second positions by coacting with said detent coacting means.
Claim 5
Dependent Claim
87 words
The switch assembly according to claim 1, wherein each of said actuatable switching means is associated with a separate lever, with one of said levers positioned near the top end of said second slot and the other lever near the bottom end of said slot, each of said levers when coacted adapted to operate said associated switching means, with said levers as positioned adapted to coact with said rod when said carriage member moves along said planar member to select either said first or second lamp assembly.
Claim 6
Dependent Claim
156 words
The switch assembly according to claim 2, wherein said detent coacting means located on said carraige member includes first and second apertures located on the surface of said carriage member with said first aperture near the top end of said second slot and the second aperture located near the bottom end of said second slot, a spring located in each aperture with a ball positioned on said spring near the top of said aperture to cause said ball to roll as said carriage is moved along said planar member, with first and second recesses positioned on said planar member defining a first and second carriage position to cause one ball to be pushed via said spring into one of said recesses for said first position indicative of selecting a first lamp assembly and to cause said other ball to be pushed into said second recess for said second position indicative of selecting the second lamp assembly.
Claim 7
Dependent Claim
42 words
The switch assembly according to claim 1, wherein said planar plate member is an "L" shaped bracket, with one arm of said bracket manifesting said planar plate member with the outer edge thereof positioned within said first slot of said carriage member.
Claim 8
Dependent Claim
26 words
The switch assembly according to claim 1, wherein each of said first and second lamp assemblies includes an associated socket for accomodating a high intensity lamp.
Claim 9
Dependent Claim
108 words
The switch assembly according to claim 1, further including a hollow housing with said planar plate member rigidly positioned within said housing to allow said carriage member to move along said planar member within said housing, said housing having a slot in a sidewall thereof with a control arm positioned in said slot and coupled to said carriage member, said housing further having an aperture in a surface adjacent to said sidewall with said aperture positioned with respect to said carriage assembly to propagate light therethrough whereby when said carriage is in said first or second position said aperture propagates light from said first or second lamp assemblies.
Claim 10
Dependent Claim
49 words
The switch assembly according to claim 1, wherein when said carriage member is moved along said planar member said lamp assemblies are positioned so that said rod will actuate said associated switching means to illuminate said associated lamp always at the same position with respect to said planar member.
Claim 11
Dependent Claim
40 words
The switch assembly according to claim 8, further including a fiber optic cable coupled to said furface of said housing and having its optical axis aligned with said aperture to allow said cable to receive light propagating through said apperture.
