Shielded switch

An EMI shielded keypad comprising:

• a printed circuit board, comprising:
• a plurality of metal traces having an exposed portion on a first surface of said printed circuit board;
• and
• a ground pad on the first surface of the printed circuit board;
• and
• a cover attached to the first surface of the printed circuit board said cover comprising;
• a flexible non-conductive essentially planar surface having an attaching face;
• a dome centered over the exposed portion of said plurality of metal traces;
• and
• a conductive coating on the attaching face of the planar surface, wherein the conductive coating is silver, said conductive coating contacting the ground pad;
• whereby pressing the dome onto the plurality of metal traces causes electrical conduction between the traces.

A radiotelephone having a receiver, a transmitter, an antenna connected to the receiver and the transmitter, and a processor controlling the radiotelephone, said radiotelephone comprising:

• a rectangular housing;
• a visual display on one surface of said housing controlled by said processor;
• and
• a EMI shielded keypad on said one surface of said housing controlled by said processor, wherein said EMI Shielded keypad comprises, a printed circuit board having a plurality of exposed conductors, a flexible non-conductive cover attached to the printed circuit board said cover having a bubble over the plurality of exposed conductors and Said cover having a conductive coating on the surface adjacent the printed circuit board, wherein the conductive coating is selectively applied to the bubble and the bubble is electrically isolated from the rest of the conductive coating.

A radiotelephone having a receiver, a transmitter, an antenna connected to the receiver and the transmitter, and a processor controlling the radiotelephone, said radiotelephone comprising:

• a rectangular housing;
• a visual display on one surface of said housing controlled by said processor;
• and
• a EMI shielded keypad on said one surface of said housing controlled by said processor, wherein said EMI shielded keypad comprises, a printed circuit board having a plurality of exposed conductors, a flexible non-conductive cover attached to the printed circuit board, said cover having a bubble over the plurality of exposed conductors and said cover having a conductive coating on the surface adjacent the printed circuit board, wherein the conductive coating is silver.
