Abstract
801,471. Piezoelectric transducers. SIMMONDS, L. E. May 29, 1956 [June 3, 1955], No. 16629/56. Class 40 (8). [Also in Group XXXVII] A piezodynamic relay comprises two rectangular bi-morph crystals, each of which is fixed at three of its corners, a reed L being connected to the free corners Q<SP>11</SP>, Q<SP>111</SP>, so that movement of the free corners in opposite directions on the application of a voltage to the crystals causes the reed to engage a fixed contact K or K<SP>1</SP> depending on the polarity of the voltage. The crystal may be of quartz, Tourmaline, Seignette salt or ceramic.
