A piezoelectric relay construction in which the active element comprises a bimorph sheet having a substantially "U" shaped perforation therethrough to present an armature section having a free end deflectable within the boundaries of the sheet and a frame section for the armature section. A first contact is mounted on the free end of the armature section and a second contact is mounted in opposition to and spaced apart from the first contact on a conductive clip affixed to the frame section. Remanent polarizations are induced in the piezoelectric layers of the bimorph sheet which are in opposition in the armature section and the frame section of the sheet. Suitable terminals on the frame section interconnected with circuit means including the electrode surfaces of the bimorph sheet are provided for the application of operating voltages. Similarly, additional terminals on the frame section and other circuit means including the contacts and conductive clip provide means for connecting the relay in external circuitry to be controlled.
