Title: Electrical switch assembly

Abstract: An electrical switch assembly for use in a photographic camera of a type having a plane shutter mechanism which is composed of leading and trailing shutter members cooperating to each other to define an exposure opening, through which exposure opening each frame of a photosensitive film is exposed to the incoming light carrying an image of an object to be photographed. The switch assembly comprises a pair of spaced contact members and a carrier lever carrying a pivotable switching lever. The carrier lever is moved from one position to another upon completion of travel of the leading shutter member at which time the switching lever is, if the trailing shutter member has not yet been moved in pursuit of the leading shutter member, pivoted to force one contact member to the other to complete the circuit.
