Abstract
There is provided an elastomeric switching device for use with electrical circuits, such as those on a printed circuit board. The elastomeric switching device comprises an elastomeric pad constructed from a plurality of parallel strips of conductive material between layers of non-conductive or insulating material together with a moveable conductive contact which is aligned with the elastomeric pad. The elastomeric pad is predisposed in contact with the circuits on the printed circuit board. The moveable conductive contact establishes electrical connections between the affected circuits via the conductive strips of the elastomeric pad. The proper alignment and orientation of the elastomeric pad and moveable conductive contact relative to the circuits is maintained by the structural and mechanical features of a housing.
