Pressure sensitive switch device

A pressure sensitive switch device, comprising:

• a membrane;
• a first conductive wire disposed on a bottom surface of the membrane;
• a second conductive wire disposed on the bottom surface of the membrane and separated from the first conductive wire;
• a pressure sensitive layer disposed on the bottom surface of the membrane and located between the first conductive wire and the second conductive wire, wherein the pressure sensitive layer contacts the first conductive wire and the second conductive wire, and the first conductive wire is electrically connected to the second conductive wire by the pressure sensitive layer;
• and
• an elastic body located over the pressure sensitive layer, comprising:
• a deformation portion located on the membrane, and the deformation portion and the membrane forming an accommodating space;
• and
• a protruding portion extended from the deformation portion and protruding toward the pressure sensitive layer, and the deformation portion being configured to generate deformation to drive the protruding portion to move in the accommodating space,
• wherein the pressure sensitive layer receives a pressing force from the protruding portion to generate a switch signal corresponding to the pressing force, and the switch signal is related to a variation of the pressing force.
