Piezoelectric triggering device support in camera flasher - has anvils mounted on holder with convex head section through hole

摘要

A support system is used to hold a piezoelectric crystal. This crystal is used in a piezoelectric triggering device for the flasher of a camera. The piezoelectric crystals are installed in a tubular insulation holder. Both sides of the crystals (2) are supported on anvils (3, 4), which are themselves supported in a holder (1). The anvils are held in position by spring loading and one produces the ignition. The ignition anvil has a spherical shaped surface (4a) which extends through a hole (1b) in the support.
