PIEZOELECTRIC SWITCH Abstract of the Invention A switch is provided wherein a piezoelectric bimorph element is used to provide many separately control- lable, closely spaced switchable contacts. The element includes at least two oppositely extending fingers connected by a common spine. The element spine is mounted to a case with the fingers spaced from an inner case surface. Elec- tronic circuit means are mounted on the element spine for applying a separate electrical potential to each of the element fingers. A separate movable electrical contact is disposed on each of the element fingers spaced from the spine and insulated from the means for applying the separate electrical potentials to the fingers. A separate stationary contact is provided on an inner case surface opposite each of the movable contacts. In operation, a separate electri- cal potential is applied to each of the element fingers for selectively causing each finger to deflect and force its movable contact into electrical connection with the opposing stationary contact.
