Abstract
For telephone sets and similar forms of apparatus in which pushbuttons are mounted more or less flush with the outside surface and actuated by pivoting, a series of such pushbuttons are mounted on a shaft secured in a housing. The pushbuttons are mounted on the shaft at one end and at the other end rest on pushbutton switch mechanisms. Each button is identical and interchangeable. Locating formations on buttons and housing interengage to locate the pushbuttons. The switch mechanisms are spring loaded and urge pushbuttons to a non-actuated position. Indicator windows for removable and interchangeable indicators can be provided.
