Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
269 words
A slide switch, comprising: (a) a casing formed in a hollow box shape with an open top; (b) a plurality of fixed contacts disposed on an internal bottom surface of said casing; (c) a plurality of terminals extending outside of said casing, each one of said terminals being electrically connected to one of said fixed contacts; (d) a cover mounted to close said open top of said casing, said cover comprising a hole opposed to said fixed contacts; (e) a slide member disposed inside said casing, comprising a control portion protruding out through said hole in said cover; (f) a movable contact portion made of a resilient electrically conducting material which has at least one leg portion directed toward said internal bottom surface of said casing such that said movable contact portion is elastically loaded against said internal bottom surface of said casing to thereby produce a biasing force on said slide member to impel it in a direction toward said cover; (g) said movable contact portion being slidable with said control portion of said slide member to selectively electrically connect said leg portion of said movable contact portion with said fixed contacts to connect a combination of said fixed contacts with each other; (h) a seal member interposed between an internal side of said cover and a side of said slide member facing said internal side of said cover, said seal member being squeezed between said slide member and said cover to provide a seal between an inside of the casing and outside thereof, a periphery of said seal member being clamped between said cover and said casing.
Claim 2
Dependent Claim
269 words
A slide switch, comprising: (a) a casing formed in a hollow box shape with an open top; (b) a plurality of fixed contacts disposed on an internal bottom surface of said casing; (c) a plurality of terminals extending outside of said casing, each one of said terminals being electrically connected to one of said fixed contacts; (d) a cover mounted to close said open top of said casing, said cover comprising a hole opposed to said fixed contacts; (e) a slide member disposed inside said casing, comprising a control portion protruding out through said hole in said cover; (f) a movable contact portion made of a resilient electrically conducting material which has at least one leg portion directed toward said internal bottom surface of said casing such that said movable contact portion is elastically loaded against said internal bottom surface of said casing to thereby produce a biasing force on said slide member to impel it in a direction toward said cover; (g) said movable contact portion being slidable with said control portion of said slide member to selectively electrically connect said leg portion of said movable contact portion with said fixed contacts to connect a combination of said fixed contacts with each other; (h) a seal member interposed between an internal side of said cover and a side of said slide member facing said internal side of said cover, said seal member being squeezed between said slide member and said cover to provide a seal between an inside of the casing and outside thereof, a periphery of said seal member being clamped between said cover and said casing.
Claim 3
Dependent Claim
25 words
A slide switch according to claim 1, wherein substantially all of said periphery of said seal member is clamped between said cover and said casing.
Claim 4
Dependent Claim
93 words
A slide switch according to claim 1, further comprising a detent means for retaining said slide member at predetermined positions relative to said casing, said detent means causing said slide member to move away from a surface of said seal member during sliding action of said slide member, said detent means comprising a rib on said slide member formed with at least one bump and a ridge on an internal side of said cover formed with at least one bump which cooperates with said bump formed on said rib on said slide member.
Claim 5
Dependent Claim
80 words
A slide switch according to claim 3, wherein when said slide member is positioned at positions other than said predetermined positions, said at least one bump on said rib on said slide member and said at least one bump on said ridge on said internal side of said cover cooperate to bias said slide member away from said internal side of said cover so as to release said seal member from being squeezed between said slide member and said cover.
