Abstract
A flexible, electrically conductive contact for a switch which is actuated upon force being applied thereto includes a first plurality of generally flexible fibers. One portion of the first plurality of fibers is constructed of an electrically nonconductive material. Another portion of the first plurality of fibers is constructed of an electrically conductive material. The flexible, electrically conductive contact further includes a second plurality of generally flexible fibers. One portion of the second plurality of fibers is constructed of an electrically nonconductive material. Another portion of the second plurality of fibers is constructed of an electrically conductive material. The second plurality of fibers is interwoven with the first plurality of fibers in the form of a sheet with the electrically conductive first plurality of fibers in engagement with the electrically conductive second plurality of fibers to form a flexible, electrically conductive sheet.
