View page
US Patent:
42912016, Sep 22, 1981
Filed:
Apr 9, 1979
Appl. No.:
6/028166
Inventors:
Walter R. Johnson - Simi Valley CA
Gary M. Petaja - Sierra Madre CA
Assignee:
American Telecommunications Corporation - El Monte CA
International Classification:
H04M 150
H04M 123
US Classification:

Abstract:
A push-button assembly in which a cluster of push-buttons arranged in a circle or in a rectangular matrix, when depressed, engage a common plate positioned beneath the push-buttons. The plate is pivotally supported at its center by a spring which urges the plate towards the push-buttons. When any of the push-buttons is depressed it engages the plate at a point spaced from the central pivot. This causes the plate to tilt about its outer periphery, compressing the spring and actuating a common switch.
