Abstract
Abstract An array of pushbuttons is formed as a one-piece molding with interconnecting flexible strips which allow for individual movement of each pushbutton. This process results in pushbutton switch assemblies which are economical and which may be placed in subscriber telephone sets without danger of misplacement of individual pushbuttons.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
49 words
A pushbutton arrangement including as components thereof a plurality of arrayed pushbuttons, a plurality of flexible strips each interconnecting certain of said pushbuttons and a surrounding frame, said components integrally formed as a single unit with said strips sufficiently flexible and configured to enable depressive operation of each pushbutton.
Claim 2
Dependent Claim
49 words
A pushbutton arrangement including as components thereof a plurality of arrayed pushbuttons, a plurality of flexible strips each interconnecting certain of said pushbuttons and a surrounding frame, said components integrally formed as a single unit with said strips sufficiently flexible and configured to enable depressive operation of each pushbutton.
Claim 3
Dependent Claim
