US4281232A — Small illuminating switch

Claim 1

Independent Claim 361 words

An illumination-type small sized toggle lever switch comprising: a housing having at least one open end; main contact contained in the housing and having at least one first movable contact element and at least one first fixed contact element; a cover member mounted on the open end of the housing said cover member including a cover mounted on the open end of the housing and a sleeve mounted on said cover; a movable operating handle comprising a cylindrical member having a hollow interior space extending longitudinally therethrough, said movable operating handle having two open ends, one open end being disposed within said housing and the other open end projecting from said sleeve; an illuminator having terminals and being disposed in said hollow interior space and at said open end of said movable operating handle projecting from said sleeve; a convertor member disposed at the other end of the movable operating handle for making or breaking the main contacts; second movable contact elements fitted to the convertor member; lead wires having bare end portions and extending in said interior space of said movable operating handle therethrough for electrically connecting said illuminator to said second movable contact elements; an insulating member being contained in said hollow interior space of said movable operating handle, said insulating member having at least two through bores through which said lead wires are led so as to be electrically connected with said illuminator; said convertor member being formed with a through opening into which said open end of the movable operating handle is fitted, and said lead wires being passed through said opening so as to be connected with said second movable contact elements; said movable operating handle consisting of a first cylindrical member and a second cylindrical member, said first cylindrical member containing said illuminator and said insulating member; said movable operating handle having a swivel portion which is received by a swivel receiver formed on the inner wall of said sleeve so that the handle can be swiveled about the swivel receiver portion as a fulcrum; and second fixed contact elements disposed within the housing and which the second movable contact elements are brought into contact.

Claim 2

Dependent Claim 361 words

An illumination-type small sized toggle lever switch comprising: a housing having at least one open end; main contact contained in the housing and having at least one first movable contact element and at least one first fixed contact element; a cover member mounted on the open end of the housing said cover member including a cover mounted on the open end of the housing and a sleeve mounted on said cover; a movable operating handle comprising a cylindrical member having a hollow interior space extending longitudinally therethrough, said movable operating handle having two open ends, one open end being disposed within said housing and the other open end projecting from said sleeve; an illuminator having terminals and being disposed in said hollow interior space and at said open end of said movable operating handle projecting from said sleeve; a convertor member disposed at the other end of the movable operating handle for making or breaking the main contacts; second movable contact elements fitted to the convertor member; lead wires having bare end portions and extending in said interior space of said movable operating handle therethrough for electrically connecting said illuminator to said second movable contact elements; an insulating member being contained in said hollow interior space of said movable operating handle, said insulating member having at least two through bores through which said lead wires are led so as to be electrically connected with said illuminator; said convertor member being formed with a through opening into which said open end of the movable operating handle is fitted, and said lead wires being passed through said opening so as to be connected with said second movable contact elements; said movable operating handle consisting of a first cylindrical member and a second cylindrical member, said first cylindrical member containing said illuminator and said insulating member; said movable operating handle having a swivel portion which is received by a swivel receiver formed on the inner wall of said sleeve so that the handle can be swiveled about the swivel receiver portion as a fulcrum; and second fixed contact elements disposed within the housing and which the second movable contact elements are brought into contact.

Claim 3

Dependent Claim 31 words

A small illuminating switch as set forth in claim 1, wherein said converter member is formed with first bores with a step, into which the second movable contact elements are fitted.

Claim 4

Dependent Claim 35 words

A small illuminating switch as set forth in claim 2, wherein said second movable contact elements each have an elastic tongue which abuts against the step formed in the first bores of the converter member.

Claim 5

Dependent Claim 76 words

A small illuminating switch as set forth in claim 2, wherein said converter member has a second bore cut into the surface thereof facing the first movable contact element, into which a telescopic slider is slidably fitted, with a coiled spring interposed between the slider and the bottom of the bore so that the telescopic slider projects from that surface and resiliently bears against the first movable contact element to make or break the main contacts.

Claim 6

Dependent Claim 18 words

A small illuminating switch as set forth in claim 4, wherein said first movable contact element is oscillatable.

Claim 7

Dependent Claim 47 words

A switch as set forth in claim 1, wherein said insulating member is made of elastic material, the terminals of the illuminator and the bare end portions of said lead wires being inserted into said through bores of said insulating member to make contact with each other.

Claim 8

Dependent Claim 24 words

A small illuminating switch as set forth in claim 6, wherein the cross section of the through bores of the insulating member is gourd-shaped.

Claim 9

Dependent Claim 24 words

A small illuminating switch as set forth in claim 6, wherein the cross section of the through bores of the insulating member is rectangular.

Claim 10

Dependent Claim 24 words

A small illuminating switch as set forth in claim 6, wherein the cross section of the through bores of the insulating member is circular.

Claim 11

Dependent Claim 43 words

A small illuminating switch as set forth in claim 6, wherein said insulating member has at least two small holes for securing the bare end portions of the lead wires thereto, said bare end portions being connected with the terminals of the illuminator.
