ABSTRACT:
A shielded switch structure is disclosed. The switch structure is adapted for use in a system which is susceptible to being affected by electromagnetic radiation. The structure includes a conductive flexible sheet disposed adjacent to a plurality of switch contacts. The sheet is operable to enable a force applied to the sheet to actuate selected switch contacts. The shielded switch structure is mounted on a postage meter conductive housing. The housing includes a recessed area adapted to receive the keyboard. The conductive flexible sheet is positioned above the conductive housing recessed area and of a size so that the margins of the flexible sheet physically engage non recessed areas of the housing.
