Abstract
A piezoelectric oscillator is described comprising a piezoelectric element, e.g. a tuning fork (10), and a casing (20) formed by a pair of glass plates (22,24). The inner surfaces of the plates have recesses (26,27) that define a housing (28) in which the tuning fork (10) is located, and a pedestal (22a) to which the tuning fork (10) is secured. The inner surface of one of the plates (22) carries a conductive track (30), in the region of the pedestal (22a). This plate (22) is also formed with a hole (44) opening onto the conductive track (30) which seals it off.
