ABSTRACT:
A camera with a built-in electronic flash has a spring-driven high energy lever that is pivoted for initiating shutter opening and for translating a switch closing member to close a normally open shutter-flash synchronization switch. When the switch reopens, it translates the switch closing member in reverse. Then, during film winding a metering cam is rotated to pivot the high energy lever in reverse. The switch closing member is adapted to be pivoted temporarily of the way of the high energy lever to allow the high energy lever to be returned past the switch closing member to an original or home position.
