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.
Claims8
A portable terminal comprising:
- a first conductor patterned on a board;
- a second conductor patterned on an outer periphery of the first conductor;
- a metal dome electrically connected to the second conductor and transformed responsive to a key being pressed so as to contact the first conductor;
- and
- an elastic supporting member configured to support a supported point of the metal dome in a state of being supported by the second conductor, and elastically move the support point of the metal dome when the key is pressed,
- wherein the elastic supporting member has an elastic index smaller than that of the metal dome.
