Abstract
Abstract An electrical swtich construction having a self-contained and completely operable electrical switch assembly disposed in a protective envelope and having leads extending from the assembly and projecting externally through an opening in one end of the envelope. A removable end closure is carried by the envelope and closes the opening of the one end thereof, the end closure having apertures therethrough and removably receiving the leads therethrough whereby the self-contained switch assembly is adapted to be carried by the end closure away from the protective envelope when the end closure is removed from the one end of the protective envelope and the self-contained switch assembly is adapted to be removed from the end closure solely by pulling the leads out of the apertures thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
In an electrical switch construction having an electrical switch assembly disposed in a protective envelope and having lead means extending from said assembly and projecting externally from said envelope out through opening means in one end of said envelope, the improvement comprising a removable end closure carried by said envelope and closing said opening means of said one end thereof, said end closure having aperture means therethrough and removably receiving said lead means therethrough whereby said switch assembly is adapted to be carried by said end closure away from said protective envelope when said end closure is removed from said one end of said protective envelope and said switch assembly is adapted to be removed from said end closure by pulling said lead means out of said aperture means thereof, said protective envelope comprising a one-piece member, said protective envelope having integral clip means thereon holding said lead means adjacent to said protective envelope.
Claim 2
Dependent Claim
154 words
In an electrical switch construction having an electrical switch assembly disposed in a protective envelope and having lead means extending from said assembly and projecting externally from said envelope out through opening means in one end of said envelope, the improvement comprising a removable end closure carried by said envelope and closing said opening means of said one end thereof, said end closure having aperture means therethrough and removably receiving said lead means therethrough whereby said switch assembly is adapted to be carried by said end closure away from said protective envelope when said end closure is removed from said one end of said protective envelope and said switch assembly is adapted to be removed from said end closure by pulling said lead means out of said aperture means thereof, said protective envelope comprising a one-piece member, said protective envelope having integral clip means thereon holding said lead means adjacent to said protective envelope.
Claim 3
Dependent Claim
159 words
In an electrical switch construction having an electrical switch assembly disposed in a protective envelope and having lead means extending from said assembly and projecting externally from said envelope out through opening means in one end of said envelope, the improvement comprising a removable end closure carried by said envelope and closing said opening means of said one end thereof, said end closure having aperture means therethrough and removably receiving said lead means therethrough whereby said switch assembly is adapted to be carried by said end closure away from said protective envelope when said end closure is removed from said one end of said protective envelope and said switch assembly is adapted to be removed from said end closure by pulling said lead means out of said aperture means thereof, said protective envelope comprising a one-piece member, said protective envelope having integral locating surface means thereon, said locating surface means comprising an elongated tapering abutment on said protective envelope.
Claim 4
Dependent Claim
159 words
In an electrical switch construction having an electrical switch assembly disposed in a protective envelope and having lead means extending from said assembly and projecting externally from said envelope out through opening means in one end of said envelope, the improvement comprising a removable end closure carried by said envelope and closing said opening means of said one end thereof, said end closure having aperture means therethrough and removably receiving said lead means therethrough whereby said switch assembly is adapted to be carried by said end closure away from said protective envelope when said end closure is removed from said one end of said protective envelope and said switch assembly is adapted to be removed from said end closure by pulling said lead means out of said aperture means thereof, said protective envelope comprising a one-piece member, said protective envelope having integral locating surface means thereon, said locating surface means comprising an elongated tapering abutment on said protective envelope.
Claim 5
Dependent Claim
172 words
In a method of making an electrical switch construction having an electrical switch assembly disposed in a protective envelope and having lead means extending from said assembly and projecting externally from said envelope out through opening means in one end of said envelope, the improvement comprising the steps of forming a removable end closure to be carried by said envelope and close said opening means of said one end thereof, forming said end closure with aperture means therethrough, removably disposing said lead means through said aperture means whereby said switch assembly is adapted to be carried by said end closure away from said protective envelope when said end closure is removed from said one end of said protective envelope and said switch assembly is adapted to be removed from said end closure by pulling said lead means out of said aperture means thereof, forming said protective envelope to comprise a one-piece member, and forming said protective envelope with integral clip means thereon for holding said lead means adjacent to said protective envelope.
Claim 6
Dependent Claim
172 words
