Abstract
A camera shutter mechanism comprises opening and closing members sequentially movable to open and closed positions to accordingly effect opening and closing of a shutter aperture to complete an exposure. The opening member engages with a contact member to move the contact member into electrical contact with a stationary contact member during movement of the opening member into its open position and the opening member returns to its initial position during the course of movement of the closing member to its closed position.
