  • Dome switch structure for a portable terminal
    Patent number: 8269124
    Abstract: Disclosed is a portable terminal, including, a first conductor formed on one surface of a board and having a contact surface, a second conductor formed at an outer periphery of the first conductor and having a support surface, and a metal dome supported by the support surface and transformed responsive to a key being pressed so as to contact the contact surface, wherein the contact surface is located at a position lower than the support surface so as to increase a transformation stroke of the metal dome.
