Structure of computer key switch

A computer key switch comprising:

• a printed circuit board;
• a locating plate spaced above said printed circuit board, said locating plate having a key body slot;
• a key body mounted on said printed circuit board and extended out of said locating plate through said key body slot, said key body comprising an outward bottom flange retained between said printed circuit board and said locating plate, two downward stop rods on two opposite sides of said key body respectively stopped against said locating plate at the top, a center through hole through a flat top surface of said key body disposed centrally therein, two opposite pin holes and two opposite retaining holes through the flat top surface of said key body, and alternatively spaced around said center through hole;
• a rubber cone made gradually smaller toward the top and received within said key body, said rubber cone comprising an annular top flange extended into the center through hole of said key body and a conductive rubber on the inside spaced above said printed circuit board;
• a key cap mounted on said key body at the top, said key cap comprising a bottom plunger stopped against the annular top flange of said rubber cone, two opposite bottom rods respectively inserted into the two opposite pin holes on said key body, and two opposite bottom hooks respectively hooked in the two opposite retaining holes on said key body;
• and
• said printed circuit board including two opposite pin holes and two opposite through holes for passing therethrough the bottom rods and bottom hooks of said key cap as said key cap is depressed;
• whereby when the annular top flange of said rubber cone is squeezed by the bottom plunger of said key cap, said rubber cone is deformed, and the conductive rubber of said rubber cone is moved down to connect with a switch on said printed circuit board, and a circuit is triggered.
