Portable electronic apparatus and key pad thereof

A key pad, used for a portable electronic apparatus, the portable electronic apparatus comprising a panel having a capacitive touch surface, the portable electronic apparatus providing a virtual keyboard interface on the capacitive touch surface, the virtual keyboard interface having a plurality of touch positions, the key pad being capable of being placed on the capacitive touch surface corresponding to the virtual keyboard interface, the key pad comprising:

• a flexible insulation pad disposed on the capacitive touch surface, the flexible insulation pad having a plurality of through holes, each through hole corresponding to one of the touch positions;
• a plurality of conductive keycaps disposed above the flexible insulation pad, each conductive keycap corresponding to one of the through holes;
• and
• a plurality of conductive contact parts, each conductive contact part being connected to one of the conductive keycaps, each conductive contact part and the capacitive touch surface forming a gap therebetween, wherein each conductive keycap is capable of being pressed such that the corresponding conductive contact part contacts the corresponding touch position through the corresponding through hole.
