Title: Quartz oscillator mountings

Abstract: A quartz crystal oscillator element including a substrate of quartz crystal having a plurality of oscillatable parallel prongs extending in a longitudinal direction of the substrate. Parallel metallic electrodes are disposed on each of the prongs thereof. The oscillator element is adhered to a supporting pedestal at a portion of the substrate thereof remote from the prongs. In the embodiment of the invention the electrodes comprise beam leads extending from an end of the substrate for receiving electrical connections to the electrodes. The beam leads are electrically connected to lead pins of additional pedestals so that the substrate bear pressure which develops during electrical connections to the beam leads.
