<p>A metal dome sheet (10) provided with a metal dome (8) which, when elastically deformed by push operation of a key top (16) provided on a board (2), becomes electrically connected to a contact (6) and which, when the key top is released from the push operation, is restored from the deformation to break the electrical connection between the metal dome and the contact. The metal dome sheet (10) has an elastic push projection (12) for transmitting push force applied from the key top (16) side to a top section (8a) of the metal dome (8).</p> |
