Claim Text:
1. A push-button structure assembled to an enclosure of a game controller, comprising: a circuit board, a top surface of the circuit board defining a plurality of conductive contacts; a conductive adhesive mounted on the circuit board, several portions of a top of the conductive adhesive protruding upward to form a plurality of elastic hollow touching portions, each touching portion being disposed corresponding to one of the conductive contacts of the circuit board, an inside of each touching portion being equipped with a conducting portion, and a bottom of the conducting portion being exposed to a bottom of the touching portion; a base column having an assembling portion, a bottom end of the assembling portion being mounted to the circuit board through the conductive adhesive and located among the touching portions of the conductive adhesive and the conductive contacts of the circuit board, a top surface of the assembling portion being concaved downward to form a receiving groove; a splinter mounted to a top end of the base column, the splinter having a base plate, several portions of an outer periphery of the base plate meandering outward to form a plurality of zigzag elastic arms, a free end of the elastic arm being bent upward to form a fastening piece; and a button body disposed to the splinter, the base column and the conductive adhesive to make the splinter located between the button body and the base column, the button body together with the splinter, the base column, the conductive adhesive and the circuit board being assembled to the enclosure, and a top end of the button body projecting beyond a top surface of the enclosure, the button body having a base portion, a middle of a bottom surface of the base portion protruding downward to form a supporting pillar, a bottom end of the supporting pillar being received in the receiving groove of the base column, a periphery of the bottom surface of the base portion defining a plurality of pressing pillars, distal ends of the pressing pillars protruding beyond a bottom of the supporting pillar, several portions of an outer periphery of the bottom surface of the base portion protruding downward to form a plurality of propping plates, each propping plate being located between two of the pressing pillars and being corresponding to one of the fastening pieces of the splinter, a bottom surface of the pressing pillar abutting against a top surface of the touching portion of the conductive adhesive, the propping plate hooking a top end of the fastening piece of the elastic arm to keep a balance of the button body.
