Abstract

A switching matrix includes at least one array (22) of piezoelectric relays having cantilevered drive elements (24) which preferably are in the form of a unitary, comb-shaped structure of piezoceramic material. Each drive element carries adjacent its free end at least one movable contact (50,52) such as a single or double bridge, for engagement with one or more fixed contacts (56,58) in either single or double throw fashion. The fixed contacts may be mounted on housing walls enclosing the relay array or on a separate substrate also mounting the drive element unitary structure. Row (R) and column (C) conductors or conductor pairs are connected into the relay contacts by non-intersecting conductor runs printed on the surfaces of the housing walls or on the substrate. <IMAGE>
