  • Bypass device for amplifier
    Patent number: 6455788
    Abstract: A bypass switch (155) for use in an electronic device (125) includes a substrate (205) on which first, second, and third terminals (215, 220, 235) are mounted and an electrically conductive primary element (250), having first and second opposing ends, mounted to a bottom surface of the substrate (205) and electrically coupled to the first terminal (215) at its first end and to the second terminal (220) at its second end. The switch (155) also includes an electrically conductive bypass element (255), having first and second opposing ends, mounted to the bottom surface of the substrate (205) and electrically coupled to the third terminal (235) at its first end and vertically aligned, at its second end, with the second end of the primary element (250). A switch actuator (225) is mechanically coupled to the bypass element (255), extends through the substrate (205), and has an actuating surface (290) accessible at a top surface, opposite the bottom surface, of the substrate (205).
    Type: Grant
    Filed: June 28, 2001
    Date of Patent: September 24, 2002
    Assignee: Scientific-Atlanta, Inc.
