Thin film switch

A thin-film press key, comprises:

• a thin film switch, further comprising:
• a bottom thin film, having at least one bottom electric conductor mounted on a top surface thereof;
• a top thin film, being disposed above the bottom thin film while spacing from the bottom thin film by a specific interval, and configured with at least one top electric conductor on a bottom surface thereof corresponding in position to the at least one bottom electric conductor while enabling the corresponding top and bottom electric conductors to be spaced from each other by a specific interval;
• and
• at least one extrusion, disposed on a top surface of the top thin film corresponding in position to the at least one top electric conductor while arranging the same to be protruding out from the top surface by a specific height;
• and
• a press key, disposed above the thin film switch at a position corresponding to the at least one extrusion;
• wherein, when the press key is being pressed, the press key is forced to press on at least one extrusion, and thereby, the top thin film is brought along to be depressed by the pressing so as to enable the at least one top electric conductor to engage with the corresponding at least one bottom electric conductor for constructing an electrical conduction.
