Abstract

A mechanism for minimizing electrostatic flashing of a lamp in a flash array by providing a short circuit across the camera socket terminals until flash firing is desired. The mechanism includes an electrically conductive piezoelectric firing spring connected to one socket terminal and an electrically conductive firing spring latch connected to another socket terminal. A short circuit is provided by engagement of the piezoelectric firing spring and firing spring latch until the piezoelectric firing spring is released to move to its piezoelectric crystal striking position.
