Title: Bypass device for amplifier

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). A downward force exerted upon the actuating surface (290) of the actuator (225) forces the second end of the bypass element (255) away from the second end of the primary element (250), thereby electrically decoupling the bypass element (255) and the third terminal (235) from the first and second terminals (215, 220).
