Abstract
A combined fill-flash/flash-defeat switch of simple and inexpensive design does not require the use of mechanical fasteners. Specifically, a camera is provided that includes a camera body, a circuit board attached to the camera body, an electronic flash unit attached to the camera body; and a fill-flash/flash-defeat control switch assembly that is retained in position by the electronic flash unit. The fill-flash/flash-defeat control switch assembly includes an electrical contact mounted to a carrier assembly, and a fill-flash/flash-defeat switch element pivotally mounted to the camera body, wherein a top portion of the carrier assembly is retained by the electronic flash unit. Guide ribs are provided on the camera body that extend through guide openings in the carrier assembly. The carrier assembly includes a post that is captured by the fill-flash/flash-defeat switch, such that lateral movement of the fill-flash/flash-defeat switch applies a force to the post to cause a corresponding movement of the carrier assembly. The circuit board includes an electrical contact group, and the electric contact mounted to the carrier assembly selectively contacts left and right electrical contac…
