  • Push-button dial assembly for telephones
    Patent number: 4291201
    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.
