ABSTRACT:
An electromagnetic shield is incorporated into a radiotelephone. The radiotelephone includes a printed circuit board having a ground trace extending around an electrical circuit formed on the printed circuit board. The electromagnetic shield is disposed adjacent the printed circuit board for isolating the electrical circuit thereon. Forming a part of the electromagnetic shield is a face, a side wall, and a series of spaced apart spring contacts that extend from the side wall for electrical contact with the ground trace on the printed circuit board. Disposed over the shield is a housing structure that engages the shield and urges the shield against the printed circuit board such that the spring contacts thereof engage and make electrical contact with the ground trace of the printed circuit board.
