<p>A film type switch is disclosed, in which a first key switch is turned on at the same position with a substantially slight press force (about 2Og ~ 8Og) which corresponds a force needed when a certain finger is softly placed on the same key, and a second switch is turned on when a strong force (over about 15Og) is applied as strong as a metal dome is transformed. When not pressed, it recovers based on a tensional force and elastic force of the film. With the above construction, the keys can be very conveniently used when a game is played or a multimedia-related edit and operation are performed, and a cursor is moved.</p> |
